I want to modify current EA

I currently have 2 EAs I will like to modify and ADD the following functionalities:

Currently EA opens positions once all signals have triggered a buy or sell condition and then EA opens after close of each candle depending settings made in EA.

I want to include:

Reverse mode

TRUE - EA will open a sell order instead of a BUY order and vice versa.

FALSE - EA will open trades as normal.

Averaging instructions similar to martingale

Position 1 will TP after 5 pips (just example, it can be any number of pips)

Position 2 will open after position 1 is in -20 pips (can be any pips).

When position 2 opens, TP for position 1 will be modified to same TP for position 2, for example 10 pips but can be changed.

For positions 3 and above, TP will be modified to 30 pips (can be changed) for all opened positions (including old and new ones), that means all previously opened positions  will have same TP as new position opened.

Will have max average position to open.

Will have max spread.

Full instructions will be given to developer that applies.
