Hi again,
As I read my own e-mail, I see that the code could be better. Here is an
improved version with a few changes:
Steve
-------------------------------------------
MovAvgPds = 13;
LookbackPds = 63;
Step = 0.25 // increment bands by this much each step
WantInChan = 85 // want 85% of bars to be inside channel
MovAvg = MA( Close, MovAvgPds );
KeepLooping = True;
For( Incr = Step; Incr < 100 AND KeepLooping; Incr = Incr + 0.25 )
{
UpperBand = MovAvg + Incr;
LowerBand = MovAvg - Incr;
InChan = High < UpperBand AND Low > LowerBand
TotalInChan = Sum (InChan, LookbackPds );
PctInChan = TotalInChan / LookbackPds * 100;
If( PctInChan >= WantInChan )
KeepLooping = False;
}
Plot( Close, "Close", colorBlack, styleCandle );
Plot( UpperBand, "Upper Band", colorBlue, styleLine );
Plot( LowerBand, "Lower Band", colorBlue, styleLine );

>> Hello.....

>> That is.....the moving average channels are great....but it's kind of
