From: "Jose" <josesilva22@xxxxxxxxx>
Subject: Breakout system code
I'm an old hand at MetaStock coding, and I thought it's time to give
AFL a go. I have to admit, AB leaves MetaStock for dead...
Anyway, here's my first AFL effort:
---8<----------------------
/* plots breakout signals */
/* josesilva22@xxxxxxxxx */
/* +1 signal=long, -1 signal=short */
Title = "Breakout system";
GraphXSpace = 10;
pds1 = Param("HHV breakout periods",10,1,252,1);
pds2 = Param("LLV breakout periods",10,1,252,1);
x = Param("Op=1 Hi=2 Lo=3 Cl=4 Vol=5",4,1,5,1);
delay = Param("Entry and Exit delay",0,0,3,1);
display = Param("signals=1 binary=2",1,1,2,1);
x = IIf(x==1,O,IIf(x==2,H,IIf(x==3,L,IIf(x==5,V,C))));
In = x>Ref(HHV(x,pds1),-1);
Out = x<Ref(LLV(x,pds2),-1);
Init = Cum(In+Out>-1)==1;
InInit = Cum(In)==1;
Flag = BarsSince(Init OR In)<BarsSince(Init OR Out)+InInit;
In = (InInit AND Ref(InInit,1)==0) OR (Flag AND Ref(Flag,-1)==0);
Out = (Flag==0 AND Ref(Flag,-1)==1)*-1;
Plot(Ref(IIf(display==1,In+Out,Flag),-delay),
---8<----------------------
Can anyone here help me with these Q's:
1) Can I control the Parameters (Ctrl-R) slider order?
2) Is the Parameters dialog box resizable?
3) Is there a way to input variable periods into EMA's?
4) Is there an equivalent to MetaStock's Prev() function?
I've got a million other questions, but I'm sure this will
sufficiently annoy enough for now. :)
Thanks,
jose '-)
