Real feedback from the ChartingLens community
"The AI signals are surprisingly accurate. I've caught several trades early that ended up being solid winners. Honestly, the backtester alone is worth the premium subscription."
"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."
"The insider trading data with cluster detection is something I check every single morning now. Knowing when multiple executives are buying their own stock gives me so much more confidence in my trades."
Latest improvements and new features
Massive AI Assistant release. Every custom indicator the AI generates now has a ☆ Save button that adds it to your personal library — a new Saved category in the Indicators menu that syncs across devices via Firestore, with info, edit (rename/redescribe), and delete actions on every entry. Every AI chat card (indicator, backtest, S/R levels) is now a proper toggle — clicking Add flips to "Remove from Chart", and a new Selected / All charts pill toggle lets you target the active pane or fan out across every chart in your layout (auto-locks in single-chart mode, live-unlocks the moment you switch to multi-chart). Switching chart panes live-updates every chat-card button so labels always reflect the active chart's state. AI prompts now correctly route through the selected chart's symbol and OHLC data — no more asking for AAPL S/R levels while looking at AAPL and getting back levels for whatever symbol chart 1 was showing. S/R lines drawn by the AI persist to Firestore as proper horizontal drawings (labels and all), so they survive page refresh just like a manually-drawn line. Plus the old "you can apply once, then it locks for an upgrade prompt" behavior on indicators and backtests is gone — removing what you added is no longer premium-gated.
Big day. The AI Assistant got a full architectural rebuild — the regex-based "guess what the user wants" intent detection that broke every time someone phrased a request slightly differently is gone, replaced with native function calling. "Apply an indicator that shows buy/sell signals", "throw on a VWAP", "build me something that highlights gaps", "lets try the RSI version instead" — whatever you say, it just works. Plus the chat now renders proper bold, headings, and lists (no more raw asterisks/hashes), every response gets thumbs up/down feedback, and buy/sell indicator requests offer 3-4 strategy options with both signal arrows AND the underlying lines visible. The AI Buy Signals panel got a redesign too — every signal now shows a color-coded Day N badge (clickable for details), a "Triggered at $X · now $Y (±%)" price-drift line, and a ⚠ Stale flag for 7+ day-old signals that have already moved more than 5%, with the exit rules (+10% TP / -5% SL / 28d max hold) summarized at the top. And the symbol search dropdown now shows your recently-viewed symbols at the top instead of generic bellwethers, persistent across devices via Firestore.
Chart any interval you want — not just the presets. A new "+" button on the timeframe selector lets you pick "every N minutes / hours / days / weeks", so 2h, 45m, 3h, 8h, 2d are all one click away. Bars are aggregated client-side from the closest base interval, so OHLC and volume stay accurate at any custom bucket size. Available on every chart in floating and docked selector modes.
