I am always reluctant of using LastValue() as I recall it slows things down by forcing loading all bars. I use Myvariable[BarCount-1] instead. 1. Is there anything wrong with that? 2. Does EndValue() suffer from same drawback as LastValue() (when no range is selected)?

Say() works fine for me. Next a simple MA crossing system. Use 'Bar Replay' to walk thru the time array and you'l' get your 'Buys' and 'Sell' ... LongMA = EMA( C, Param("Long Period", 50, 30, 100, 5 )); ShortMA = EMA( C, Param("Short Period", 5, 3, 50, 1 )); Buy = Cross( ShortMA, LongMA ); Sell = Cross( LongMA, ShortMA ); if (EndValue(Buy)==1) Say("Buy"); if (EndValue(Sell)==1) Say("Sell"); Ton. ----- Original Message ----- From: Herman <mailto:[EMAIL PROTECTED]> To: [email protected] Sent: Saturday, December 23, 2006 12:17 PM Subject: RE: [amibroker] Re: using say("text") (AmiBroker 4.89.0 BETA released ) You need to store any text to ouput in a staticvar and clear this variable after you output it, below is just one way of doing this. This will only Say() text when is has changed. You may have to change this when you need repetative messages, like pyramided trades that say Buy, Buy, Buy, ... Text = ParamStr("Enter text to synthesize","Test"); PrevText = StaticVarGetText("PrevText"); if ( Text != PrevText ) { Say( Text ); StaticVarSetText ("PrevText", text); } best regards, herman -----Original Message----- From: [email protected] [mailto:[EMAIL PROTECTED] Behalf Of J.
