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 );

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
