[amibroker] Re: Formula question

CS,
Well, never say never.
Although MA(C,10) and ROC(C,10) are different curves, they may give 
cross points for many stocks. Perhaps not for a high value index, 
like ^NDX but certainly for many stocks of $1, $5 or even $50.
ROC(C,10)may be >100.
Just run the
Filter=1;
AddColumn(Highest(ROC(C,10)),"");
for the n=1 last quotation and you will see.
Except this, it is meaningless to compare ROC(C,10) with a price 
average, the probable crosses are coincidental...
