[amibroker] Re: Using Equity to Compute Position Size

Trading Reference Links

Here is how I do it based on % loss of account equity per trade and a ATR multiple for max loss.

//-----------------------------------------------------------
SetOption("InitialEquity", 100000);

CompoundSwitch = 0;

BuyBarsSince = BarsSince(Buy == 1);
ATROpen = Ref(ATR(20),-BuyBarsSince);
BuyPriceOpen = Ref(BuyPrice,-BuyBarsSince);
HHVOpen = HighestSince(Buy == 1,High,1);

ATRXLoss = 2;
ATRXBELoss = ATRXLoss;
MaxFEATR = (HHVOpen-BuyPriceOpen)/ATROpen > ATRXBELoss;

LossStopLevel = IIf( MaxFEATR == 1, .00001, ATRXLoss*ATROpen);
ApplyStop(stopTypeLoss, stopModePoint, LossStopLevel, 1, True );

PositionNum = 6;
SetOption("MaxOpenPositions", PositionNum );
Capital = GetOption("InitialEquity");
AcctRiskPct = 0.02;
PositionSizeNoCmpd = Capital * AcctRiskPct / (ATRXLoss*ATRopen) * BuyPriceOpen;
PositionSizeCmpd = -100 * AcctRiskPct * BuyPriceOpen / ATRXLoss / ATROpen;
PositionSize = IIf(CompoundSwitch == 0,PositionSizeNoCmpd,PositionSizeCmpd);
