Greetings sir, I have included them, https://fxdreema.com/shared/GGffw17Vb
great thanks.
For number 3 "If the remaining trade hits the SL then you want a reverse trade (a sell in your example), but I don't understand the new % and TP to be applied. Can you please provide a numercial example.",
it is just to extend/modify stops of SL&TP of the new reverse position,
if it were buying at 50pips SL and 50pips TP and then hit the stop loss, lt should then sell with new stops extend by say 50% of old trade, that means the new stops will be 75pips each SL/TP.
Regards.
