check out the linregslope indicator, for instance: x = Cum(1); lastx = LastValue( x ); Daysback = 10; aa = LastValue( LinRegIntercept( Close, Daysback) ); bb = LastValue( LinRegSlope( Close, Daysback ) );
y = Aa + bb * ( x - (Lastx - DaysBack) ); Plot( Close, "Close", colorBlack, styleCandle ); Plot( IIf( x >= (lastx - Daysback), y, -1e10 ), "LinReg", colorRed ); ----- Original Message ----- From: convertah To: [email protected] Sent: Wednesday, August 13, 2008 6:55 PM Subject: [amibroker] Trendline Indicator Kind Greetings, I have been trying to code an indicator that will render a trendline that will be used as a support-resistance reference line. The trendline would be drawn through yesterdays 9:30AM candle (open+close)/2 and yesterdays 4:00PM candle (open+close)/2 and extend into today. I'm new to AFL and after l studied the users guide on AFL function references I realized I'm not sure where to even start. If someone could give me a little starting push it would be greatly appreciated. Thank you, All the best Geary
