thanks sir, I appreciate your help

thank you for answering .
firstfull sorry for my bad english
yes I used this strategy manually and it works as long as your wining trades are 50% of 20 consecutive trades and risk to reward ratio 1/1. I am talking about scalping trades 30pip sl 30 pips tp . you just need 2 consecutive trades to close the sequence and start again with minlot . ah I use this strategy on range bars . don't tell me that you can't find 2 consecutive range bars

Can someone help me to add this martingale strategy?
the principle is simple: - When you lose the next trade will be the same size - When you have a gain after one or more losses the following trade will size the previous accumulated losses Suppose we start to lose one lot (-1), we still trade 1 lot we still lost (-2), then we win the next position in one lot (-1), now we're going to add the equivalent of what we lost to (= 2 lots) if we win we are in +1
For example, let’s say that we have a sequence of trades like this,

• Loss 1 lot, loss 1 lot , loss 1 lot , loss 1 lot , win 1 lot, now we are in -3 lots; we enter with 4 lots if it wins we are in +1 if it loses we enter again with 4 lots until we get a wining trade then the following trade will size the previous accumulated losses +1 unite
