I've tried to copy/paste from source the Take Profit indicator renamed TP, set the CustomIndicator = true, CTRL+I and no error message. In back testing the TP does not work but original Take Profit it is working.

Can you help me please ?

I want to have a custom TP where the TP value to be calculated base on internal logic not a fix value like the original one. I have started with first step, copy the original one base on your source code and no success.

Thank you,
