Custom martingale EA MT4

Hi 

EA must have magic number and can work in multiple currency individually , no indicator required 

EA need to open one long and one short position to test the market tp is 5 pip , 

Start lot is 0.01 

So one order will reach TP and will close and need to open another order with Same open direction 

for example if is uptrend direction and long order hit the TP. EA need to open another short position with bigger size 

If goes up next 5 pip need to open another position with bigger size , so we are betting on wrong direction with bigger size 

so what is the bigger size 

so every next order size must be calculated accordance current total lose or current opens lot size , for example if we are in losing $100 with current positions , next position size must be 2 lot x 5 pip to would be $100TP , if last position hit the TP need to close all position togheter and again one long and one short to test the market
