That should work. I am doing essentially the same and it works for me.
I don't see where you are setting BuyPrices, but I don't think this
affects the results.

OC = ParamField("Trade price", field = 0 );
BuyPrice = SellPrice = ShortPrice = CoverPrice = OC

Also you are not setting this and maybe that is the problem:
SetOption("UsePrevBarEquityForPosSizing",False);

Hi,

This should be simple but I am obviously missing something...

I want to limit position size in a portfolio backtest and have the 
following code:

//-------------------------------------
SetFormulaName("LastWeek");                //name in backtest report
SetBarsRequired(4000,1);                   //needed line 
SetTradeDelays(1, 1, 1, 1);               //open & close trades delay
SetOption( "initialequity", 100000 );        //initial capital
PositionSize = 10000;                       //trade size
RoundLotSize = 10;
SetOption( "MaxOpenPositions", 10 );        //max trades open
SetOption( "PriceBoundChecking", 1 );       //trade within days bar

//--------------------------------------

However when I run the backtest the AA results show trades entered 
that exceed $10,000 in value.

What am I missing here?

regards
Chris
