Modification of current ea trailbea

I need to modify the attached ea in order to:

- cut unnecessary part of the code like hidden stop loss, code of last position in multiple position management, wait until macd new signal, second trailer both in single and multiple position.

- review the code of the  ea to check what  causes the ea to be very slow in back testing

- adjust martingale logic: today multiple applied only to 1st lot for all positions after the 1st one. IN future  multiple, as alternative option and in addition to the present one,  should be:

- applicable also to all lots after the first one: Multiple X 1st lot, multiple X 2nd lot, multiple X 3rd lot.... up to maximum level allowed

-  incremental of 1st lot: example first lot  0,03, incremental 0,01: lots should be 0.03, 0.04,0.05......

 Candidate should apply showing understanding of the job and suggestions how to do it.
