A Simple Martingale EA ( Buy ) Some Special Function, Buy in Pair at Same time on another Pair

Example;  Buy EurUsd, at the same time - Buy on UsdJpy.

"I need it to have an option in the EA, to choose the currency pairs, in which the Buy will be made respectively."

I will illustrate how the EA should close trades
*No StopLoss.
*First target is $1
*When the first trade is losing -1$, the Ea needs to make Buys 0.02 trades, on both pairs; eurusd and usdjpy

*Always look at the negative balance of the account, not points.
When there is negative -1$, the next martingale will be made when it is -2$.
Like this;
-1$ > buy 0.02 at eurusd and usdjpy
-2$ > buy 0.04 at eurusd and usdpjy
-4$ > buy 0.06 at eurusd and usdjpy
-8$ > buy 0.08 at eurusd and usdjpy
so on and on.

All trades must be closed when the first one is closed, so all trades close in profit.
When it close, Start all from the beginning.
