Overlay QQQ and SPY on the P&L chart, with correlation
+420 lines (estimated)The cumulative P&L chart now draws QQQ and SPY too: the left axis is cumulative P&L in dollars, the right axis each index's % change from the first day of the range. Each index can be switched on or off in the legend (remembered in the browser), and hovering shows that day's P&L and both indexes' change. So the lines line up the curve is now on a trading-day axis: days without a closed trade keep the P&L flat. Below the chart is a correlation table: Pearson r between realized P&L and the index return, per day and per week (only days or weeks with realized P&L), with a note on how to read it. It works on every broker page, the summary and any chosen range. Daily closes come from Yahoo Finance's public data, cached in the database and retried at most every 10 minutes; if they cannot be fetched the page falls back to the plain P&L chart with a notice. The share image is unchanged and still shows only the P&L curve.
