Hello everyone.I'm strying tu build a strategy based on the Supertrend indicator,but i have only the prorealtime version: a = AverageTrueRange[3](close) b = 1.1 if barindex < 3 then T = 1 L1 = low H1 = high else if T[1] = 1 then if close > L1[1] then L1 = MAX(L1[1],medianprice - a*b) ST = L1 else H1 = medianprice + a*b ST = H1 T = -1 endif else if close <H1[1] then H1 = MIN(H1[1],medianprice + a*b) ST = H1 else L1 = medianprice - a* b ST = L1 T = 1 endif endif endif return st I'm not so expert in metastock language.Could anyone help me to translate in metastock language the formula above? Thanks a lot in advance

Code:
 

Factor:= Input("Factor", 1.00,10.00,3.00); 
Pd:= Input("ATR Periods", 1,200,10);
Up:= MP() + (factor * ATR(Pd)); 
Dn:= MP() - (factor * ATR(Pd));
Td:= If(Cross(C, LLV(Up, 13)), 1, If(Cross(HHV(Dn, 13), C), -1, PREV));

DNX:= If(Dn = HighestSince(1, Cross(Td, 0), Dn), Dn, PREV);
Upx:= If(Up = LowestSince(1, Cross(0, Td), Up), Up, PREV);
ST:= If(Td = 1, DNX, If(Td =- 1, UPX, PREV));
ST

This secon version is with thanks to Roy Larson of MSTT
Code:
 

Factor:=Input("Factor",1,10,3); 
Pd:=Input("ATR Periods",1,200,10);
Up:=MP()+(factor*ATR(Pd)); 
Dn:=MP()-(factor*ATR(Pd));
Cu:=Cross(C,LLV(Up,13));
Cd:=Cross(HHV(Dn,13),C);
I:=Cum(IsDefined(Cd+Cu))=1;
Td:=ValueWhen(1,Cu+Cd+I,Cu-Cd);
I:=Cum(IsDefined(Cd+Cu))=2;
Hs:=Dn=HighestSince(1,I+Cross(Td,0),Dn);
Ls:=Up=LowestSince(1,I+Cross(0,Td),Up);
Dnx:=ValueWhen(1,Hs,Dn);
Upx:=ValueWhen(1,Ls,Up);
SuperTrend:=If(Td=1,Dnx,Upx);
SuperTrend;

Here is a chart of UTX using the SuperTrend indicator provided by Roy Larsen with the MTF filter on only long trades.

It needs a trend filter to only trade long when the trend is your friend.

Thank you for your reply,but there are some difference between roy version and prorealtime version,both with an atr period 3 and factor 1.1. http://uploading.com/files/ae4c4b97/Roy.doc/ http://uploading.com/fil...orealtime%2BVersion.doc/ Prorealtime seems to be more effective

Noumann, please upload your charts to imgur.com, then post the link here.

I hate to have to download images from the web.

opps..i miss the code: inputs: ATRLength(NumericSimple), ATRMult(NumericSimple), Strength(NumericSimple), STrend(NumericRef); vars: ATR(0), avg(0), dn(0), up(0), trend(1), flag(0), flagh(0), ST(0), hl(0); hl = Highest(High, ATRLength) - Lowest(Low, ATRLength); ATR = XAverage(hl, ATRLength); avg = (XAverage(high, Strength) + XAverage(low, Strength))/2; up = avg + ATR; dn = avg - ATR; if c > up[1] and c > Highest(High, Strength)[1] then trend = 1 else if c < dn[1] and c < Lowest(Low, Strength)[1] then trend = -1; if trend < 0 and trend[1] > 0 then flag=1 else flag=0; if trend > 0 and trend[1] < 0 then flagh = 1 else flagh = 0; if trend > 0 and dn < dn[1] then dn=dn[1]; if trend < 0 and up > up[1] then up=up[1]; if flag = 1 then up = avg + ATR; if flagh = 1 then dn = avg - ATR; if trend = 1 then ST = dn else ST = up; SuperTrend = ST; STrend = trend;

Any suggestions? Thank you

So that others don't have to go through the pain of the download process:

Code:

{==== 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);
{ Paint bars}
Flag:=input("PaintBars On=1, Off=0",0,0,1);
[linestyle=pricecolor; color=rgb(98,217,98)]
If(Trend=1 and Flag=1,1,if(Flag=0 and C>O,1,undefined));
[color=rgb(226,118,118)] {red}
If(Trend=-1 and Flag=1,1,if(Flag=0 and C<=O,1,undefined));



BullScript is very similar to MS script, but it's more powerful and has some really nice features not available in MS, however, the essence of the code should be immediately evident to anyone who has taken the time to learn the basics of MS coding by reading and understanding the MS User Manual and doing the basic exercises in the free Equis Formula Primer.

wabbit, the first part is quite simple: Mult:= Input("ATR Multiplier",0.1,3,1); Nb:= Input(“NbPeriods”,1,8,8); x:= Input(“Price:[1](H+L)/2 [2]Close”,1,2,1); TruRan:= Wilders(ATR(1),Nb)*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)); but i can't translate the second part. Can you help me? Thanks

The forum is still borking the codes, but then again you're not using the proper code tags either....

wabbit, maybe this can be a decent translation: Mult:= Input("ATR Multiplier",0.1,3,1); Nb:= Input("NbPeriods",1,8,8); x:= Input("Price:[1](H+L)/2 [2]Close",1,2,1); TruRan:= Wilders(ATR(1),Nb)*Mult; HiLimit:=If(x=1,(H+L)/2-TruRan,C-TruRan); LoLimit:=If(x=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)); Super:=If((Trend=1 AND Ref(Trend,-1)=-1) OR (Trend=1 OR Trend=0),LB,UB); Super; Whato do you thing about it?

i don't know what happens. i can't write the complete code in the post.I try again: Mult:= Input("ATR Multiplier",0.1,3,1); Nb:= Input("NbPeriods",1,8,8); x:= Input("Price:[1](H+L)/2 [2]Close",1,2,1); TruRan:= Wilders(ATR(1),Nb)*Mult; HiLimit:=If(x=1,(H+L)/2-TruRan,C-TruRan); LoLimit:=If(x=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)); Super:=If((Trend=1 AND Ref(Trend,-1)=-1) OR (Trend=1 OR Trend=0),LB,UB); Super;
