Good idea, pasting your code in. I tried it and it wouldn't pass the
AFL editor checker by itself. Then I added, before your code, the
following:
//=========== beginning of additional code ===========
s=0.636;
function T3(price,periods)
{
e1=EMA(price,periods);
e2=EMA(e1,Periods);
e3=EMA(e2,Periods);
e4=EMA(e3,Periods);
e5=EMA(e4,Periods);
e6=EMA(e5,Periods);
c1=-s*s*s;
c2=3*s*s+3*s*s*s;
c3=-6*s*s-3*s-3*s*s*s;
c4=1+3*s+s*s*s+3*s*s;
Ti3=c1*e6+c2*e5+c3*e4+c4*e3;
return Nz(Ti3);
}
//=========== end of additional code ========================
That worked for me just fine. Check your T3 code. Also, don't
forget to use the AFL checker in AB's editor.
BTW, I don't see how you could get a buy and sell on the same bar
using the cross function as you did.
BTW2, I like Graham's suggestion. I've had problems in the past with
not being able to see some arrows (hidden in a bar)(and it can also
make debugging easier if sometime time you do have a buy and sell on
the same bar).
