[amibroker] Scale out affects initial positionssize

["Thomas" <tzg@xxxxxxxxxxxxxxxxxxx>]

hello,

i have some troubles with scale out. I have defined some rules to 
scale out and basically the code works. However it also affects the 
positionsize at entry. When a trade has any scale out, than the 
positionsize is also reduced. I can't find the reason. Does anyone 
know some possible reasons that i could check ?
This is the part at the end of my code:

PositionSize = -RiskAmount * MarginDeposit / RiskPerContract;
SetPositionSize(ScaleAmount, IIf( Buy == sigScaleOut, 
spsPercentOfPosition, spsNoChange ) );
SetPositionSize(ScaleAmount, IIf( Buy == sigScaleIn, 
spsPercentOfPosition, spsNoChange ) );
SetPositionSize(ScaleAmount, IIf( Short == sigScaleOut, 
spsPercentOfPosition, spsNoChange ) );
SetPositionSize(ScaleAmount, IIf( Short == sigScaleIn, 
spsPercentOfPosition, spsNoChange ) );

and this is the part inside my trading loop:

if(E_USDRdiff[i] == 0.25 AND IRstatus == 0)
{ IRstatus = 0.25; ScaleAmount[i] = 25; Buy[i] = sigScaleOut; }
else if(E_USDRdiff[i] >= 0.50 AND IRstatus == 0)
{ IRstatus = 0.50; ScaleAmount[i] = 50; Buy[i] = sigScaleOut; }
else ScaleAmount[i] = 0;

Regards
Thomas
