Subject: [amibroker] Re: PREV of MS in AmiBroker(3rd TIMES)
Excuse-me, but
I'm have nothing
too.
IT's maybe because I'm made a
mistake
When i'm give to you my formula, I'm
write:
(C>HautP AND C>BasP,5,
If(C<BasP,0,PREV) )
But the right formula is:
If(C>HautP
AND C>BasP,5, If(C<BasP,0,PREV) )
It's my mistake
Excuse me
Thank
Merci

You should PLOT the result variable, not "Bon"
variable.

Hello,
This MS code:
result = (C>HautP AND
C>BasP,5, If(C<BasP,0,PREV) )
can be translated to:
result = 0;
for( i = 1; i < BarCount; i++
)
{
prev = result[ i - 1];
result[ i ] = IIF( C[ i ] > HautP[ i ] AND C[
i ] > BasP[ i ], 5, IIF( C[ i ] < BasP[ i ], 0, prev )
);
}
Although loop version is longer, it will execute 100 faster than in
Metastock, because
MS PREV is extremely inefficient.

Subject: [amibroker] PREV of MS in
AmiBroker
I’m try to translate this formula(Metastock) in Amibroker(AB)
(C>HautP AND C>BasP,5,
If(C<BasP,0,PREV) )
A guy from AB said to use the loop.
I’m use a formula on site Internet of AB(Percentage Trail
Stop)
Why when I’m use my Formula, I’m obtain :
Error 6. Condition in IF, WHILE, FOR statements has to be Numeric or
Boolean type. You can not use array here, please use [] (array subscript
operator) to access array elements
And when I’m use the formula Percentage Trail
Stop,
I don’t obtain ERROR 6
???????????? ?
WHY ???????
Thank
YLTech
