hello, if there is a buy entry @1.0000 but the market goes down and on the next candle it starts @0.9700 which means the martingale will double the entry but the wont close all on profit, there will be a loss depending on the big candle. so i want the same pips in T/P but the lot size should change.

Martingale
how can I set up a martingale that calculate the body of the candle and set the T/P accordingly without moving the 30pips T/P?
it must calculate the body of a candle and when it takes the new trade it must be based on body of the candle.

thanks in advance.
