Why these two
Most people searching for politician trades want the trades themselves, not an essay about them, so the tracker puts the filings in a table and our guide on tracking politician stock trades covers the background. The calculator exists because position sizing is the piece of risk management most people skip, and it is simple arithmetic once someone lays it out.
When you want to take an idea further, the ChartingLens chart app has the full charting side: indicators, drawing tools including long and short position tools, alerts, and the Politicians and hedge fund panels.
