Mt 4 supertrend

I want to create an MT4 code on XAUUSD for broker compatible for 2 decimal symbols. For trading , we should follwing trend filter as supertrend 10 3. For buy signal , it will take buy entry for 150 pips target. if price falls below then it should average the entry with below combinmation. Entry lot- 0.02. Next averaging lots 0.04, 0.08, 0.03, 0.06, 0.12,0.04,0.08,0.16,0.05,0.10,0.20a nd so on. ALso, keep averaging TP 150 points above avg value. Keep on averaging loosing position till the trend is on the same side. if the trend flips and there are open position, open equal amount of hedge position. again target of 150 points and averaging at 500 points. Keep two seperate counter for running profit and hedging profit. Obce the postion enters in hedging mode, calculate hedging profit. If hedging profit 1.02 X floating loss, then exit all open position. and start new trades as per the trend again.
