Thanks for the reply chuck. TrailingStop is the LLV value of the
past three days (ignoring inside periods). I don't want to initiate
a short position until the lowerstop is violated. It sounds like I
might have to create a FOR loop. Could you give me a basic piece of
code on how to do this type of LongOpenPosition and
ShortOpenPosition?
Here is the sample code that I was writing (run this as an
explore). Everthing works except the LongPosition because I cannot
initialize the ShortPosition == 0 until the array is run. Take a
look and see if you can figure it out.
//3-Bar Pattern Exploration
Filter=1;
//Bar Number
AddColumn(BarIndex(),"Bar Index");
//Identifys number of lookback bars to ignore inside days
Countbars=BarIndex()-ValueWhen(Inside()==0,BarIndex(),4);
//Long and Short Setups
HigherClose = C > Ref(C,-1);
LowerClose = C < Ref(C,-1);
AddColumn (HigherClose,"Higher Close");
AddColumn (LowerClose, "Lower Close");
//3-bar stop level
ThreeBarLow = LLV(L,Countbars);
ThreeBarHigh = HHV(H,Countbars);
//Recalculates stop based on a higher close or lower close
LowerStopLoss = IIf(HigherClose, ThreeBarLow, Ref(ThreeBarLow,-1));
UpperStopLoss = IIf(LowerClose, ThreeBarHigh, Ref(ThreeBarHigh,-1));
AddColumn (LowerStopLoss,"3-Bar High Stop");
AddColumn (UpperStopLoss,"3-Bar Low Stop");
//Long and Short stop loss levels
LongStopOut = C < LowerStopLoss;
ShortStopOut = C > UpperStopLoss;
AddColumn (LongStopOut,"LongStopOut");
AddColumn (ShortStopOut,"ShortStopOut");
//Identifying if there is an open long or short position
LongEntry = HigherClose;
LongPosition = Flip(LongEntry,LongStopOut);
ShortEntry = LowerClose AND LongPosition == 0;
ShortPosition = Flip(ShortEntry,ShortStopOut);
AddColumn (LongPosition,"LongPosition");
AddColumn (ShortPosition,"ShortPosition");
