Hi,
Just a few "coding-style" comment:
Things like this:
> PL = iif(PL==
1,1,iif(ref(PL,-1)== 1,1,iif(ref(PL,-2)== 1,1,0))); are not needed
because all comparison operations (<,>, <=, >=, == and !=)
return
1 (true) when condition is met and 0 (false)
otherwise.
So you can omit IIFs at all:
PL = PL == 1 OR Ref( PL == 1, -1 ) OR Ref( PL == 1, -2
);
Second comment: Ralf pointed out
that it is much better to use BarsSince
function instead of joining multiple Ref()s
:
>tolDays = 3;>kupBuy
= iif(barsSince(CROSS(C,KDOWN) ) < tolDays, 1, 0);>kupSell =
iif(barsSince(CROSS(KUP,C) ) < tolDays, 1, 0);<FONT
size=2>
But you can simplify the formula even
further using Hold function:
tolDays = 3;
kupBuy = Hold( Cross( C, KDown
), tolDays );
kupSell = Hold( Cross( KUp, C
), tolDays );
Best regards,
Tomasz Janeczko

little easieron the typing and you can play with the period:
tolDays = 3;.../* KUP
