This sample is unique to my own trading systems but you should be able
to manipulate this code as needed. The trailing Stop is set at
previous days close minus 0.50, and if the stock Opens below that
figure then it takes you out of the trade at the Open price. And this
particular trading system does not set a Stop Loss on the day that a
position is entered.
Just my way of doing it.
Good luck... Phsst
SetTradeDelays(1,0,0,0); // Affects Back Test (not Scan or Explore)
Buy = <buy condition>
LongBars = BarsSince(Buy==0); // Used to prevent S/L on 1st day
SellPrice = IIf(LongBars == 2,0,Ref(L - .50,-1)); // No S/L 1st Day
-(2 needed for SetTradeDelays)
PrevSellPrice = IIf(SellPrice == 0,0,Ref(L - .50,-1)); // Trailing
SellPrice = Max(SellPrice,PrevSellPrice); // Stop
SellPrice = Min(SellPrice,O); // Loss
Sell = L <= SellPrice;
