Hello,
No. Ref is NOT the same as PREV.
Prev is usually used for RECURSIVE formulation, therefore LOOP must be used or
AMA/AMA2
function
Conversion to loop is pretty straightforward.
1. Create standard loop
2. define temporary variables for PREV "emulation"
3. Re-type the MS line with CC instead of C
and IIF instead of IF,
If((C*.97)>PREV,C*.97,If((C*1.03)<PREV,C*1.03,PREV))
to:
result = 0;
for( i = 1; i < BarCount; i++ )
{
PREV = result[ i - 1 ];
CC = C[ i ];
result[ i ] = IIf( (CC*0.97) > PREV, CC*0.97, IIf((CC*1.03) < PREV, CC*1.03,
PREV));
}
It is longer than MS code but... advantage is that it runs 100 times faster.
Best regards,
Tomasz Janeczko
