MFE minus realized R is the giveback metric
Giveback = MFE - realized R on winners, and MFE on losers (open profit you never banked). Example: 30 winners, mean MFE 2.40R, mean realized 0.70R, mean giveback 1.70R. At $500, that is $850 left on the table per winner, $25,500 per 30. Losers: 20 tickets with mean MFE 0.55R then -1.00R is another $5,500 of unbanked scalp. TP1 at 1.50R on 40% volume would have captured part of both tails.
If mean MFE is only 0.90R, your 3.0R TP2 is fantasy. Put TP2 at 1.10R or change the strategy. Do not "hold for 3R" against a 0.90R MFE histogram.
Calibrating TP1 to TP4 from MFE percentiles
Use 40th percentile MFE for TP1, 60th for TP2, 75th for TP3, 90th for a runner. Gold H1 book: 1.4R, 2.1R, 3.0R, 4.2R. Volume slices 40/30/20/10. 24/7 MT5 Bot Control executes those slices with 0.01 lot rounding and a BE-plus-buffer after TP1 so MFE cannot fully return through entry after you already saw 1.4R.
