Hi, Can anyone help with some issues I am having with Super Trend indicators? I am using the indicator to trade long only in SMSF. I only want to take signals when price is trading above the indicator. None of my indicators with my criteria work when i include the code line: c>Formula("Super Trend Wilders", 3, 30, Wilders, 2). I have copied this formula I presume off here somewhere as below: {==== BullScript ====} [Description="SuperTrend - Max"] [target=price] Mult:=Input("ATR Multiplier",3,1); Nb:=Input("Nb Periods",8,1); method:=inputma("Method",Wilders); price:=Input("1=Median, 2=Close",1,1); TruRan:=ma(ATR(1),Nb,method)*Mult; HiLimit:=if(price=1,(H+L)/2-TruRan,C-TruRan); LoLimit:=if(price=1,(H+L)/2+TruRan,C+TruRan); LB:=If(HiLimit>=PREV and HiLimit<C,HiLimit,If(C<PREV,HiLimit-0.1,PREV)); UB:=If(LoLimit<PREV and LoLimit>C,LoLimit,If(C>PREV,LoLimit+0.1,PREV)); Trend:=if(UB>ref(UB,-1),1,if(LB<ref(LB,-1),-1,prev)); [drawundefined=gap] [Color=lime green] if(Trend=1 and hist(Trend,1)=-1,LB,if(Trend=-1,UB,undefined)); [Color=red] if(Trend=-1 ,UB,if(hist(Trend,1)=1 ,LB,undefined)); [Color=lime green] if(Trend=1 or Trend=0,LB,undefined); When I display the Super Trend indicator in a pane all of its own so it should show "0" when price below indicator and "1" when above. It only shows "1" when price crosses above when it immediately does not each day that it is true. Appreciate any help. Thanks Dean  |

It probably doesn't constantly show a 1 or 0 due to the 'undefined' output for changing the line colours. This similar indicator is easier to adapt. The last line should provide the digital output you're looking for. { Stop Trail ATR } [Target=price] atrper :=Input("ATR period: ",14); atrfact:=Input("ATR multiplier: ",2); loss:=atrfact*ATR(atrper); trail:= If(C>PREV and Ref(C,-1)>PREV, Max(PREV,C-loss), If(C<PREV and Ref(C,-1)<PREV, Min(PREV,C+loss), If(C>PREV, C-loss, C+loss))); Trail; { digital signal: if close is above previous value it's in buy(1) else it's in sell(0) } direction := if(close>prev,1,0); |
