Given that your average win is nearly your limit at $200 (+$195)
and your average loss is dang close to -$200 at -$185, it'd be a sweet thing to bump that upside TP to $250 and dump that SL down to $175, and see what happens. I know your playing, so if I missed some rule or R:R convention to which your ascribing that was mentioned above, "Apologies."
But, "Nice Thread!"
R:R is 'average' price curvature dependent .. If you bump up the TP and drop SL , its not optimized for tick reversions or spikes. Through testing found 16 ticks : 16 ticks achieves the best results at those time intervals and signals.
