Re: [amibroker] Re: Plot of MA Loop

Hi Peter,

Sorry about that, I thought your question was about how to plot. I looked at
your code and it looks like what you are trying to do is find and plot the
shortest-period MA that remains below the price for the last year - is this
correct? If so, you could try something like this (untested):

found = 0;
For( pd = 2; pd < 253 AND NOT found, pd++ )
{
    CurrentMA = MA( Close, pd );
    PriceBelowMA = Close < CurrentMA;
    BarsBelowMA = Sum( PriceBelowMA, 252 );
    If ( BarsBelowMA[BarCount-1] == 0 )
        Found = True; // break out of loop
}
If ( Found )
    Plot( CurrentMA, NumToStr( pd, 1.0 ) + " pd MA", colorBlue, styleLine );
Else
    Plot( 0, "No MA Meets Criteria", 0, styleNoLine|styleNoLabel );

Steve
