ChartingLens combines charting, AI research, and smart alerts into one platform — but with so much packed in, new users often don't know where to start. This guide is the shortest path from "just signed up" to running a real trading workflow. We'll walk through the same three-step loop we use ourselves: find a trade, research it with AI, then set an alert so you never miss the entry.

The flow is the same whether you're swing trading, day trading, or investing for the long term. By the end of this guide you'll know what every feature does and exactly when to use it.

Your first 5 minutes: Sign in (it's free, no card required), type a ticker into the search bar at the top, and load a chart. Then open the AI Chat on the right sidebar and ask "Give me a quick read on this stock." That single prompt shows you most of what makes ChartingLens different — try it before reading any further.

The 3-Step Workflow at a Glance

1

Find a Trade

Use AI Buy Signals, the Stock Screener, Hedge Fund Holdings, an AI scan of your watchlist, or the AI Pattern Screener to surface ideas worth looking at

2

Research It

Use the AI Chat, CL Score, and stock info to backtest, check news, and validate the setup

3

Set Your Alert

Drop a price, indicator, or trendline alert so the platform watches the trade for you 24/7

Three steps. That's the whole loop. Let's break each one down.

Step 1: Finding a Trade

Before you can trade anything, you need to know what to trade. ChartingLens gives you five different ways to surface opportunities, each suited to a different style.

AI Buy Signals

Best for: Quick discovery

Let the Algorithm Do the Work

AI Buy Signals is a curated list of stocks that our proprietary algorithm has flagged. Each stock on the list is either actively in a trade (meaning the algorithm has identified a current setup and is tracking it) or being watched for a potential entry soon.

The system scans the market using the CL Score, historical pattern matching, and technical momentum to rank opportunities by confidence. You get a list sorted by the stocks most likely to move, along with the algorithm's win rate and average gain for each signal based on historical data.

How to use it: Open AI Buy Signals from the sidebar, browse the ranked list, and click any stock to load its chart. From there, you move to Step 2 and research it further before deciding to take the trade.

Stock Screener

Best for: Custom criteria

Find Stocks That Match Your Exact Setup

If you have a specific set of criteria you look for in a trade, the Stock Screener lets you build your own filter. This is for traders who already know what they want and just need the platform to surface stocks that match.

You can filter using two types of criteria:

What makes this screener different is the dual-timeframe mode. You can set technical criteria on two different timeframes simultaneously. So if you want a stock where the MACD is bullish on both the daily and the weekly chart, you can filter for exactly that. This is useful for confirming that a setup aligns across timeframes before committing to a trade.

Two shortcuts worth knowing: curated presets give you one-click scans like "$3-10 High RVOL Gappers" and "Short Squeeze Candidates", and Screener Loadouts let you save an entire filter setup under a name so your go-to scan is one click every morning — synced to your account.

How to use it: Open the Stock Screener tab at the bottom of the app, set your fundamental and technical filters, choose your timeframe(s), and hit Run Scan. Click any result to load the chart.

Hedge Fund Holdings

Best for: Following smart money

See What Legendary Investors Are Buying

Every quarter, institutional investors with over $100M in assets are required to file a 13F form with the SEC disclosing their holdings. ChartingLens tracks 18 of these investors, including Warren Buffett, Michael Burry, Ray Dalio, Stanley Druckenmiller, and more, and lets you browse their portfolios in real time.

Every holding carries a recent-buy badge — NEW BUY, BOUGHT +X%, or SOLD −X% — so you can see at a glance exactly what changed since the previous quarter, and a Recent Changes view filters the entire list down to just the moves.

The Performance view goes a step further: for each fund it estimates the portfolio's return since its latest filing, benchmarks it against SPY to show real alpha, and assigns a risk score. Click any fund card for the deep dive — sector mix, concentration, this quarter's new buys and trims, and which positions are driving the returns. So before you copy a legendary investor's trade, you can check whether their recent picks are actually working.

And the overlap detection cross-references all tracked investors and highlights stocks that multiple hedge fund managers are buying simultaneously. When several of the world's best investors are independently loading up on the same stock, it gives you a strong signal about where institutional capital is flowing.

Real example: We noticed that both Michael Burry and Warren Buffett had bought UNH (UnitedHealth Group) in the same quarter. That overlap signal led to a trade that returned over 80% in a single week. Overlaps don't guarantee results, but they are one of the strongest conviction signals you can find.
How to use it: Open Hedge Fund Managers from the sidebar, browse individual portfolios or switch to the Performance or overlap views. Click any holding to load the chart.

Scan Your Watchlist With AI Premium

Best for: Working your own list

Let the AI Pick the Best Setup From Stocks You Already Follow

If you already keep a watchlist, you don't have to check every chart on it one by one. Open the AI Chat and ask:

"Can you look at My Growth Watchlist and tell me which ticker is likely the best opportunity?"

The AI evaluates every symbol on the list and comes back with the strongest candidate and the reasoning behind it — so your morning routine goes from twenty chart-checks to one question.

You can also rank the list by any of 17 fundamental metrics. Ask things like:

How to use it: Build a watchlist (you can bulk-import a comma-separated ticker list), then reference it by name in the AI Chat. The AI fetches live data for every symbol before answering.

AI Pattern Screener Premium

Best for: Trading classic chart patterns

Scan the Entire Market for Chart Patterns With One Question

Chart patterns are one of the oldest edges in trading — the hard part has always been finding them. Flipping through hundreds of charts hunting for a clean double bottom is a full-time job. The AI Pattern Screener does it in about a minute: ask the AI Chat in plain English and it runs live pattern detection on real price data across 2,000+ liquid US stocks — or just your watchlist.

Try prompts like:

It detects double tops and bottoms, head & shoulders (and inverse), triangles, wedges, channels, and flags on any timeframe from 15-minute to weekly. Progress streams into the chat while the scan runs, and every result shows the pattern's direction (bullish or bearish) and freshness — including a "forming now" tag for setups completing on the current bars. Click any symbol to load its chart, then ask the AI to "add Master Chart Patterns" to see the exact pattern drawn on the candles.

Scans stick to liquid, major-exchange names, so every hit is a stock you can actually trade — no pink sheets, no stale tickers.

How to use it: Open the AI Chat and ask for a pattern in plain English. Say "the market" (or nothing) to scan everything, or name a watchlist to scan just your list. Prefer clicking to typing? The same detection engine also powers the Chart Pattern filter in the Stock Screener, where you can combine it with every fundamental and technical filter.

Step 2: Researching Your Trade With AI

You've found a stock that looks interesting. Now you need to decide whether to actually trade it. This is where the AI Chat becomes your most important tool.

Open the AI Chat from the right sidebar. It is a chat box that understands your chart — when you ask a question, it can read what's on screen, run backtests, draw lines, and pull live news. You talk to it in plain English, no setup or scripting required. It can even operate the platform for you — add symbols to your watchlist, switch timeframes, or rank your entire watchlist by any of 17 fundamentals, just by asking. There are two models: the free model handles indicators, technical questions, and backtests, while the premium model Premium adds live web search for real-time news, earnings, and market data, plus Pine Script conversion.

Backtesting a Strategy

AI Chat

Test Your Strategy Before You Risk Real Money

One of the most powerful features of the AI Chat is natural language backtesting. Instead of writing code or configuring complex settings, you just describe your strategy in plain English.

For example, you could type: "Backtest a strategy that buys when RSI crosses above 30 and MACD crosses bullish, and sells when RSI hits 70."

The AI will apply the strategy to the stock's historical data, draw all the relevant indicators on your chart, and return stats including win rate, average gain, and total trades. You can see exactly where the strategy would have entered and exited.

Find Best Timeframe Premium: After backtesting, use the "Find best timeframe" feature to see which timeframe your strategy performs best on. The AI will test it across multiple timeframes and give you a summary explaining why a particular one outperforms, whether it is because of less noise, stronger trend signals, or better risk-to-reward ratios.
AI Signal Tournament Premium: Not sure which strategy to test? Ask: "Can you give me an indicator that has buy and sell signals?" The AI backtests seven classic signal strategies — EMA crossover, MACD cross, RSI mean reversion, Bollinger bounce, Stochastic cross, Supertrend flip, and Donchian breakout — on your exact symbol and the timeframe you're currently on, then shows you the full list ranked by win rate, total return, and profit factor so you can see which signals actually perform best on your chart. Apply or save the winner in one click.

Checking the News

Ask the AI Chat about recent news for any stock. This is useful when a stock has made a big move and you want to understand why before deciding whether the move is likely to continue or reverse. Simply ask something like "What's the latest news on TSLA?" and the AI will give you a summary of recent events and catalysts.

Asking About a Position You Already Hold

AI Chat

Answers That Adapt to What You're Actually Asking

The AI doesn't give the same canned analysis to every question — it reads your intent and changes the entire shape of its answer:

Every direct "is it a buy" question gets a verdict-first answer — the call comes first, the supporting analysis after, so you're never hunting for the conclusion.

Support and Resistance Levels

AI Chat

Get Key Levels Drawn Directly on Your Chart

Ask the AI for support and resistance levels on any stock and it will identify the key price levels and draw them directly on your chart. You can even ask for levels on specific dates or timeframes.

This helps you identify where to enter a trade, where to set your stop loss, and where to take profits. Instead of eyeballing levels, you get AI-calculated zones based on price action and volume data.

Screenshot AI Analysis

Already have drawings on your chart? Trendlines, support/resistance zones, Fibonacci retracements? Use the Screenshot AI feature to capture your chart and ask the AI to analyze it. Ask things like:

The AI analyzes the visual chart, including your drawings, and gives you feedback. It is like having a second set of eyes on every trade.

Smart Money Concepts

Ask the AI to "detect Smart Money Concepts" on any chart and it will plot Fair Value Gaps, order blocks, and supply/demand zones directly onto your candles. If SMC isn't your style, you can ask for any other technical concept the same way — the AI handles all the drawing for you.

Building Custom Indicators in Plain English Premium

AI Chat

If You Can Describe It, the AI Can Build It

Beyond the 40+ built-in indicators, you can ask the AI to build any indicator you can describe:

Every rule you specify is honored exactly — the AI generates the indicator, runs it against your actual chart data, and self-corrects before you ever see the Apply button. That includes conditional colors: describe a line that turns red in overbought and green in oversold, and that's what you get, bar by bar.

Every AI-built indicator updates live as new candles form, shows its parameters in the pane legend with a settings gear to tweak them, and can be saved to your personal library — cloud-synced, so your custom toolkit follows you to any device. Popular presets (RSI, MACD, Bollinger, Stochastic, ATR, SMA, EMA) apply instantly without using an AI credit.

Comparing Multiple Tickers at Once

Deciding between several candidates? Ask something like "Compare NVDA, AMD, and AVGO — which has the best setup right now?" The AI pulls full data for every ticker in the request — price action, support/resistance, analyst targets, growth, and news — for up to 20 tickers in a single question, and answers with a real side-by-side comparison instead of analyzing just the first name.

Converting Pine Script Indicators Premium

AI Chat

Bring Your Favorite Indicators With You

Have an indicator written in Pine Script that you don't want to trade without? Paste the source code directly into the AI Chat and it converts the script into a live, native chart indicator — plots, boxes, zones, trend lines, and labels all render through the charting engine, and the script's input settings stay editable from the indicator legend.

The converter validates its own output by dry-running the indicator against your live chart data before showing you the Apply button, and tells you honestly if any part of the script had to be approximated. Once applied, you can save it to your indicator library and reuse it on any chart, on any device.

Saving a Strategy as a Live Alert

Ran a backtest you really like? After the results come back, you can activate the same strategy as a live alert in one click. The AI keeps watching the market and sends you a notification (email if you're premium Premium) the moment your next buy or sell signal fires — no need to re-run the backtest yourself.

CL Score

Quick Read

Get a Bull/Bear Score in One Glance

The CL Score is a proprietary rating from 0 to 100 that summarizes the technical health of any stock. It factors in trend strength, momentum, volume confirmation, and support/resistance levels.

The CL Score is visible in the stock info panel on the sidebar. Use it as a quick sanity check after your other research: if everything else looks good but the CL Score is low, it might be worth waiting for conditions to improve.

You can also ask the AI Chat general questions about market sentiment, sector performance, or anything else you need to build conviction before entering a trade.

Step 3: Never Missing an Opportunity

You have found a trade and done your research. Maybe the stock isn't quite at your entry level yet, or you are waiting for a specific technical signal to trigger. This is where alerts come in, so you don't have to sit and watch the chart all day.

ChartingLens alerts run in the background every five minutes even when your browser is closed, so you can walk away and let the platform watch the trade for you.

Price Alerts

The simplest alert type. Set a target price level and get notified when the stock crosses it. Right-click anywhere on the chart to quickly set a price alert at that exact level, or use the alerts panel in the sidebar. Great for entries, exits, or just keeping an eye on a stock you are interested in.

Indicator Alerts

Multi-Condition

Trigger on Technical Signals, Not Just Price

If your trading strategy is based on technical indicators, you can set alerts that trigger when specific conditions are met. Supported indicators include:

You can combine multiple conditions into a single alert and even set conditions across different timeframes. All conditions must be true at the same time for the alert to trigger, so you get precise, high-conviction signals.

The fastest way to set one: click the "+" button directly on an indicator pane (RSI, MACD, Stochastic, ADX) to drop an alert at that exact value — with an editable value box to fine-tune the level before you set it. Every alert also has a trigger mode (once or every time), candle-close or live-price evaluation, an optional expiration, and a custom message.

Example: Set an alert for when MACD crosses bullish on the daily chart AND RSI is below 40 on the weekly chart. You will only be notified when both conditions are true simultaneously.

Trendline Alerts Premium

Advanced

Get Notified When Price Breaks Your Trendline

Draw a trendline on your chart, then right-click it to set an alert. You have two trigger modes:

The candle close mode is especially useful for avoiding false breakouts. A quick wick through a trendline does not trigger the alert. Only a confirmed close on your chosen timeframe (1-hour, daily, weekly, etc.) will fire the notification.

Pro tip: Combine this with the AI Chat. Ask the AI to draw support/resistance or trendlines for you, then set a trendline close alert on the daily timeframe. You will be notified only on a confirmed break, giving you a high-probability entry signal without staring at the chart.

Custom Indicator Signal Alerts

New

Alert on Your Own Indicator's Buy/Sell Signals

This is where alerts and the AI assistant meet. Ask the AI to build a custom indicator with buy and sell signals — for example, "Build an RSI indicator that marks a buy at the 30 value and a sell at the 70 value" — and once it's on your chart, click the bell icon in the indicator's legend. Pick whether you want buy signals, sell signals, or both, choose your notification channels, and ChartingLens will alert you the moment your indicator prints a new signal on a closed bar.

Signal alerts are checked live while ChartingLens is open and the indicator is on your chart — leave a tab running and any strategy you can describe in plain English becomes a hands-off signal watcher.

Prompts to try — any custom indicator that draws buy/sell markers gets the alert bell. Paste one of these into the AI Chat, apply the result, then click the bell:
  • "Build an RSI indicator that marks a buy at the 30 value and a sell at the 70 value" — the classic oversold/overbought reversal watcher
  • "Make an indicator that marks a buy when the 9 EMA crosses above the 21 EMA and a sell when it crosses back below" — trend-following crossover signals
  • "Mark a buy when MACD crosses bullish while RSI is below 40, and a sell when MACD crosses bearish" — a two-condition confirmation setup, so you're only pinged on higher-conviction signals
  • "Give me buy arrows when price touches the lower Bollinger Band and sell arrows when it reaches the middle band" — mean-reversion entries with a defined exit
  • "Create an indicator that marks a buy when price closes above the 20-day high and a sell when it closes below the 10-day low" — a Donchian-style breakout watcher for swing entries
Each of these becomes a live indicator on your chart first — so you can see exactly where its signals would have fired historically before you decide to arm the alert.
Pro tip: Run the AI Signal Tournament first to find which signal strategy has actually performed best on your exact chart, apply the winner, then arm a signal alert on it. You've gone from idea to backtested, alert-monitored strategy in three prompts.

All alerts show up as in-app notifications with sound, and premium users also receive email notifications Premium so you can stay informed even when you are away from your computer.

Bonus: Practice Mode & Charting Toolkit

The three-step workflow above is the core loop. Everything below supports it — and the first one (Bar Replay) might be the most underrated feature on the platform.

Bar Replay & Paper Trading Premium

Practice

Trade Past Markets Like It's Live

Bar Replay rewinds any chart to a past date and steps forward candle by candle. You can place real long or short orders with stop losses and take profits, and your P&L is tracked just like a live trade — except no money is on the line.

Use the random date button to jump to a moment in history you don't recognize. That's the only honest way to test your chart-reading skills, since you can't peek at what happens next.

Why it matters: Real traders rarely get enough screen time on real setups. Bar Replay lets you compress months of practice into an afternoon — the F1-simulator equivalent for chart reading.
★★★★★

"I've used a lot of platforms over the years and features like the AI Chat auto-drawing support and resistance and the plain-English backtester are things I've never seen anywhere else. They genuinely feel like magic."

— Sarah K., Day Trader (2 years on ChartingLens)

Charting Toolkit

Everything you need to actually read a chart is built in. Most of these are free.

Strategy Simulator

Want to know whether an entry idea works across the whole market, not just one chart? The Strategy Simulator tests an entry strategy (RSI oversold, 20-day breakout, golden cross — or a random-entry control group to keep you honest) with your exit rules across the entire ~1,900-symbol stock universe in seconds, and lets you compare two runs side by side to A/B test your ideas.

Everything is cloud-saved and syncs between your devices in real time: draw a trendline on your desktop and it appears on your phone within a second — same for watchlist edits, indicators, saved layouts, and recent searches. And a saved layout now captures your entire workspace — chart arrangement, symbols, timeframes, every indicator (including custom AI-built ones) and all your drawings — so loading it brings back exactly the setup you saved.

Frequently Asked Questions

ChartingLens offers five main discovery tools. AI Buy Signals surfaces stocks the algorithm is actively tracking or watching for entry. The Stock Screener lets you define custom fundamental and technical filters, including across two timeframes, with saveable loadouts and one-click presets. Hedge Fund Holdings shows what 18 legendary investors are buying through their SEC 13F filings, with performance tracking since each filing, recent-buy badges, and overlap detection to find stocks multiple investors are loading up on. The AI Pattern Screener scans 2,000+ liquid US stocks for classic chart patterns — just ask "What stocks have a double top on the 1h chart?" And you can ask the AI Chat to scan your own watchlist — "Can you look at My Growth Watchlist and tell me which ticker is likely the best opportunity?" — for an instant ranked read on the stocks you already follow. Start with AI Buy Signals for quick ideas, or use the Stock Screener if you have specific criteria.
The AI Chat backtests strategies you describe in plain English and draws the results on your chart, fetches recent news and explains why a stock moved, calculates and draws support/resistance levels, and analyzes screenshots of your chart to give visual feedback on your setup. It also converts pasted Pine Script into live native indicators, runs a Signal Tournament that ranks seven classic strategies on your exact chart, builds custom indicators from plain-English descriptions, and can operate the platform for you — switching symbols, managing watchlists, and ranking them by fundamentals. You can also ask general questions about market sentiment, sectors, or trading concepts.
Yes. ChartingLens runs an alert checker in the background every five minutes using a server-side process. This means your price alerts, indicator alerts, and trendline alerts are being monitored even when you are not on the platform. Premium users receive email notifications when alerts trigger, so you never miss a signal regardless of whether your browser is open.
The CL Score is a proprietary technical analysis rating from 0 to 100. It combines trend strength, momentum indicators, volume confirmation, and support/resistance analysis into a single number. A high score (70+) indicates bullish technical conditions, while a low score (below 40) suggests bearish conditions. Think of it as a quick health check for any stock's technicals. You can see it in the stock info panel on the sidebar.
Yes. The core charting platform, including charts, indicators, drawing tools, and watchlists, is completely free. The AI Buy Signals, AI Chat, CL Score, and stock screener are available with limited free usage, and you can earn additional free access through the daily login streak rewards. Premium unlocks unlimited access to all features plus email alert notifications for $14.99 per month.
