hi to all bs forum members, i`m pretty new at BS. I have a swing indicator formula, that I often use in MS. could somebody help me to convert these 2 formulae in bullscript? SWING REVERSAL UP m1:= H<Ref(H,-1) AND L<Ref(L,-1); m2:= H<Ref(H,-2) AND L<Ref(L,-2) AND H>Ref(H,-1)AND L<Ref(L,-1); m3:=H<Ref(H,-3) AND L<Ref(L,-3) AND H>Ref(H,-2) AND L<Ref(L,-2) AND H>Ref(H,-1) AND L<Ref(L,-1); mark:= m1 OR m2 OR m3; set:=L >ValueWhen(1,mark,L) AND H>ValueWhen(1,mark,H) AND LowestSince(1,Ref(mark,-1),L) > ValueWhen(1,mark,L); sig:= If(mark,1, If(set,0,PREV)); Cross(sig=0,0.5) SWING REVERSAL DOWN m1:= H>Ref(H,-1) AND L>Ref(L,-1); m2:= H>Ref(H,-2) AND L>Ref(L,-2) AND H>Ref(H,-1) AND L<Ref(L,-1); m3:= H>Ref(H,-3) AND L>Ref(L,-3) AND H>Ref(H,-2) AND L<Ref(L,-2) AND H>Ref(H,-1) AND L<Ref(L,-1); mark:= m1 OR m2 OR m3; set:=L<ValueWhen(1,mark,L) AND H<ValueWhen(1,mark,H) AND HighestSince(1,Ref(mark,-1) , H) < ValueWhen(1,mark,H); sig:= If(mark,1, If(set, 0, PREV)); Cross(sig=0,0.5) Thank you :) |

hey charlie
Looks good on weekly charts like MMS. Add medium to long average, trading only in direction of that larger trend.
{ SWING REVERSAL UP }
[target=price] m1:= H<Ref(H,-1) AND L<Ref(L,-1); m2:= H<Ref(H,-2) AND L<Ref(L,-2) AND H>Ref(H,-1)AND L<Ref(L,-1); m3:=H<Ref(H,-3) AND L<Ref(L,-3) AND H>Ref(H,-2) AND L<Ref(L,-2) AND H>Ref(H,-1) AND L<Ref(L,-1); mark:= m1 OR m2 OR m3; set:=L >ValueWhen(1,mark,L) AND H>ValueWhen(1,mark,H) AND LowestSince(1,Ref(mark,-1),L) > ValueWhen(1,mark,L); sig:= If(mark,1, If(set,0,PREV)); [name=Up; linestyle=marker; marker=type1;] SWRup:=Cross(sig=0,0.5); SWRup { SWING REVERSAL DOWN }
[target=price] m1:= H>Ref(H,-1) AND L>Ref(L,-1); m2:= H>Ref(H,-2) AND L>Ref(L,-2) AND H>Ref(H,-1) AND L<Ref(L,-1); m3:= H>Ref(H,-3) AND L>Ref(L,-3) AND H>Ref(H,-2) AND L<Ref(L,-2) AND H>Ref(H,-1) AND L<Ref(L,-1); mark:= m1 OR m2 OR m3; set:=L<ValueWhen(1,mark,L) AND H<ValueWhen(1,mark,H) AND HighestSince(1,Ref(mark,-1) , H) < ValueWhen(1,mark,H); sig:= If(mark,1, If(set, 0, PREV)); [name=Dwn; linestyle=marker; marker=type2;] SWRdwn:=Cross(sig=0,0.5); SWRdwn |

hey maximo, thank you for recoding those indicators for BS. Those formulae both are from the book "Trading Triads" (the author is Felipe Tudela), that I bought some months ago.

| I found that there are some much better ways to trade those swing reversals (triads), than to use any MAs or other tecnical indicators. I dont use them at all, I am more a price action guy :) |

Thanks for sharing those swing indicators charlie. The logic is sound and they can provide a statistical edge as part of a trading plan. They are based on price action, so that would be of help to many out there looking at price action strategies, which work well in most markets. I consider Darvas boxes another price action method, since they are not based on mathematical calculations.

Never say never ;) I found Hull 9/21 MAs very interesting for determination of the trend direction. Could you pleace write the ribbon for me, red for downtrend, blue for uptrent? The triads are looking very interesting with HMAs :) Thank you!

Here's a ribbon for the Hull dual moving averages.
[Description="Hull-MA Dual Moving Average Ribbon"]
[target=ribbon] per1:= input("Period1",9,1); per2:= input("Period2",21,1); ma1 := ma(2*ma(C,int(per1/2),W) - ma(C,per1,W),int(sqrt(per1)), W); ma2 := ma(2*ma(C,int(per2/2),W) - ma(C,per2,W),int(sqrt(per2)), W); [color=Blue; name=Above] SignalAbove:= ref(ma1,1) >= ref(ma2,1); SignalAbove; [color=Red; name=Below] SignalBelow:= ref(ma2,1) < ref(ma1,1); SignalBelow; Here are the same moving averages plotted on price
[Description="Hull-MA Dual Moving Averages"]
[target=price] per1:= input("Period1",9,1); per2:= input("Period2",21,1); ma1 := ma(2*ma(C,int(per1/2),W) - ma(C,per1,W),int(sqrt(per1)), W); ma2 := ma(2*ma(C,int(per2/2),W) - ma(C,per2,W),int(sqrt(per2)), W); [color=Blue; name=Above] ma1; [color=Red; name=Below] ma2; |

thank you very much maximo! I found also that adding hma (50) hepls to filter out many bad trades, try it and I'll be happy if you like it.  but i would never buy on close or on open of a next bar (how Tudela suggested), but only on breakout of the high of the bar.

I was retesting various fractal definitions to see if I could find an improvement on John Crane's action reaction pivot point method, and had another look at Tudela's Triad definition. (Triads are otherwise known as fractals or pivot points),
The above post has some code named Metastock Swing indicator which in fact the Metastock code for his Tudela's Triad indicator provided in Metastock format on page 213 - 214 of Tudela's book quoted in citation below. So it is not actually an indicator for a swing but the bar after a fractal or pivot point. I had previously color coded the fractal bars in Bullcharts when the book came out but I did not really find them useful at the time so stored the indicator away. But this time in playing around with the code I added two lines using Tudela's code and the additional lines now colour code the continuation or swing bars leading into and after his triad definitions so they show similar thing to resultant trend or swing as Tudela would define a Swing. The two extra lines are just adapting his original Triads So you can play around with this. There are black bars not colour coded and this seems to arise as they reflect inside bars or outside bars which Tudela's code does not deal with. I will post a chart and then the code so you can play around with it further ------------- BC User since June 2007 |

Seems to be usual problem loading images so here is code:
