I am looking for someone to automate my strategy on ninja trader

I would like to benefit from your expertise which consists in adding to my automatic strategy which is on ninjatrader this code I want you to show me how and where precisely I must add it in the line code of my automated ninjatrader strategy for it to work I don't know if you need to make any changes to make it work on ninjatrader I'm not a computer expert but the only thing I know is that it's done in C# language like the ninjatrader base

in terms of how the strategy works:

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 the trader equivalent of what we lost to (= 2 lots) if we win we are in +1
