TradeView with sample trades. Your fills are drawn straight onto real candles.
Reviewing numbers alone only goes so far. TradeView pulls up the candlestick chart for the window a trade happened in and marks the entry and exit, so you can see what you acted on and where you should have left.
You can also pick a period and sweep through every trade in it. Put winners and losers side by side and the repeating entry pattern becomes visible.
