Yes, just add these 2 lines onto the end of that code.

[name=Envelope Fill; linestyle=fill; color=blue]

avg+channel/2; avg-channel/2;

Hi Maximo

The formula in your post 159 above --- is it possible to fill the channel with any color?

I will have a read of his book :)

Here's a link to a report & a couple of videos which present the idea of combining all 3 market conditions into 1 trading plan using a channel.

Actually there's also a few mechanical systems that have been using this idea for over 15 years in the live market. eg. R-breaker + R-Levels by Richard Saidenberg and Cyclone system by Clayburg.

Thanks Maximo. You are a genius with Bullscript.

I am trying to follow Dr Alexander Elder's short term trading within the channels, as described in 'Come into my Trading Room.

Okay, there you go, looks okay for testing a breakout strategy.

[target=price]

EMA:=input("Base EMA",22,1);

Factor:=input("Factor",27,1);

avg:=ma(C,EMA,E);

asize:= Stdev(2*Max(Abs(H-avg) ,Abs(L-avg)) / avg,100)*Factor/10; {Use 100 days for stable channel size - default is 2.7 std}

bsize:= ValueWhen(1, DayOfWeek()<Ref(DayOfWeek() ,-1) OR ( DayOfWeek()=Ref(DayOfWeek(),-1) AND DayOfMonth() <> Ref(DayOfMonth(),-1)) ,Ref(asize,-1)); { This pegs the Stdev to last bar of week and only changes once per week}

csize:=LastValue(bsize); {fix to constant using last value}

channel:=csize*avg;

avg+channel/2;

avg-channel/2;

avg;

Got this MS formula for the same thing from another web source. The parameters of this
look more closer to description in the book, as compared to the previous formula so please ignore it.

EMA:=input("Base EMA", 22, 1, 100);
Factor:=input("Factor", 27, 1, 50);
avg:=ma(C,EMA,E);
csize:= Stdev(2*Max(Abs(H-avg) ,Abs(L-avg)) / avg,100)*Factor/10; {Use 100 days for stable channel size - default is 2.7 std}
Csize:= ValueWhen(1, DayOfWeek() Ref(DayOfMonth(),-1)) ,Ref(csize,-1)); { This pegs the Stdev to last bar of week and only changes once per week}
csize:=LastValue(csize); {fix to constant using last value}
channel:=csize*avg;
avg+channel/2;
avg-channel/2;
avg;

Hi All

Below is formula in Metastock for Autoenvelopes as discussed in Alexander Elder's books. Is it possible to convert them to bullscript?
thanks

{user inputs}

pds:=input("EMAperiods", 21,1, 252);

pdsBak:=input("lookbackperiods", 42,1, 252);

x:=input("use: Open=1,High=2, Low=3, Close=4, WClose=5", 4, 1,5);

plot:=input("[1]AutoEnvelope,[2]Long signals, [3]All signals", 1, 1,3);

delay:=input("Entry/Exitsignals delay", 0, 0, 5);

{ Price field }

x:=If(x=1,O,If(x=2,H,If(x=3,L,If(x=5,WC(),C))));
