Hello I'm testing the scripting language to randomly open position, then increase the lot size based on the amount of positions I have open already and if the sum of the positions are losing.
The issues are 2:
1) I cannot seem to open more than 1 of the smallest tradeable unit in oanda fxtrade, regardless of the amount of Lots I insert(Lots = 1, Lots = 6 etc etc.)
2) therefore going back to the code when there are more than 5 positions open it doesn't increase the lot size as it should, therefore it doesn't continue trading.

I need the script to do exactly what I've tried described below. I'm aware that there are different ways to open lot sizes, but i wanted to see if zorro is capable of doing it this way.

This is the code for the lot size opening:

Any help will be greatly appreciated.
Code:
function run()
{
  StartDate = 2016;
  BarPeriod = 5; 
  LookBack = 500;
  Hedge = 5:

if (WinTotal < 0*PIP)
	if(NumOpenTotal < 5)
	{
		Lots = 1;
	} 
	if((NumOpenTotal > 6) and (NumOpenTotal < 10)) 
	{
		Lots = 2;
	}
	if((NumOpenTotal > 11) and (NumOpenTotal < 15))
	{
		Lots = 3;
	}

  if(NumOpenTotal == 0) { 
    if(random() < 0)
      enterShort();
    else 
      enterLong();
  }
}
