[amibroker] How to reset POSITIONSIZE

["Werner" <WKRAG@xxxxxxxxxxx>]

Hi there,

the following is my backtest for trading a portfolio of 10 stocks
according to some BUY and SELL rules. Thanks to Yuki, Fred and Graham,
I have figured out how to do this now. 

SetOption ("MaxOpenPositions", 10);

PositionSize = -100 / 10 ;  // trade a portfolio of 10 stocks
PositionScore = C;            // prefer the highest priced stocks

Buy  = MyBuyConditions; 
Sell = MySellConditions;

Short = MyShortConditions AND Name() == "QQQQ";
Cover = Buy;

For going SHORT, I want to trade the QQQQ only, but with FULL equity.
Unfortunately, I can not figure out, how to reset Positionsize. It
always trades only 10% of equity (which is correct for going LONG, 10%
of equity for 1 stock). But for going SHORT I want to trade the FULL
equity with the QQQQ (just 1 position). How do I reset POSITIONSIZE ?

Thanks for any suggestions.

Werner
