Yeah that happens on some stocks. I don’t have enough time to debug this and fix it so if someone knows how to fix it please say so.

Here’s the corrected snippet of code -

//////////////////////////////////////
do
 {
 Over = H > Middle + X ;
 Under = L < Middle - X ;
 OuterPct = 100*( Sum( Over, LookBkPd ) + Sum( Under, LookBkPd )
 )/LookBkPd ;
 OP = LastValue(OuterPct) ;
 Y= X + sign( OP - ExternalBarPct )*deltaX;
 
 }while ( sign( OP - ExternalBarPct ) > ConvergePct ) ;
 Plot( Middle, "MA", colorYellow, styleLine|styleNoTitle ) ;
 Plot( Middle+Y, "MA", colorSkyblue, styleDashed|styleNoTitle ) ;
 Plot( Middle-Y, "MA", colorSkyblue, styleDashed|styleNoTitle ) ;

////////////////////////////////////

The problem was occurring because of usage of ‘abs’ function in the ‘while’ loop which gave rise to the fact that the ‘abs’ value of algorithm for some stocks was always above the reference value.

However, be aware that this formula looks into the future!

Excellent work mike works a treat now :).

Glad to be able to help :)

hello any one tray to put email alert i have formula but work in this AlertIf( Buy, “Email”, "BUY triggered for " + Name() + " at price Rs."+WriteVal(C,5.2), 1,1+2 );
this formula work other indicator so tray to set in formula
