=> Cum(Inside()) Cum or inside has not a period/length of bars parameter?
while EasyLanguge's CountIf(expression, Length) can specify the Length, how can I similiarly control the Length when using the Cum? Ref(Cum(Inside()), -Length) ? So it will Cum the Length bars only? Sorry I'm still rather newbie to AFL. ________________________________ From: msc626 <[email protected]> To: [email protected] Sent: Saturday, February 14, 2009 7:09:12 PM Subject: [amibroker] Re: EasyLanguage CountIf function Or Cum(Inside() ); daleb > Thanks.
