Enter your entry, stop, and exit. Returns the trade's R-multiple, dollar P&L, and percent return. R is the universal language of trade journaling - a +2R win is a +2R win whether you traded 100 shares of a $50 stock or one E-mini contract. Track the average R across hundreds of trades to know if your edge is real.
