These may not be all the errors, but just a couple in quick look
At the sigscale you should use BuyPrice
Buy[i] = sigScaleOut;
BuyPrice[i] = FirstProfitTarget + PriceAtBuy;
and at teh exit you need to use Sell
if(Exit == 2)
{
Sell[i] = 1;
In your short section make sure you use Short and Cover, not Buy and Sell
