Yes, replacing   ATR(15) >= ATRvalue  by Wilders ( H-L, 15 ) >= ATRvalue  will neglect the interday gaps.

Note that Wilders(H-L, 15) = EMA(H-L, 29), so you may want to try shorter periods.

hi

Can you confirm that this is correct?

Price = Param ( " Price ", 10, 10, 1000, 5 ) ;
Today_Vol = Param ( " Today's Volume ", 400000, 100000, 150000000, 1000 ) ;
AvgVol = Param ( " Average Volume ", 400000, 100000, 150000000, 1000 ) ;
ATRvalue = Param ( " ATR ", .8, .5, 5, .1 ) ;

Myfilter = Close > Price AND V >= Today_Vol AND EMA (V, 30) >= AvgVol AND Wilders ( H-L, 15 ) >= ATRvalue ;

thanks

The Range is just (H-L) vs. the True Range that Wilder's ATR() uses.

 

If you want to apply ATR-type averaging to  (H-L), use Wilders( (H-L), Periods) instead of

MA( (H-L), Periods) or EMA( (H-L), Periods).

Hi all,

I've been using Average True Range for quite sometime for my stock criteria selection but I would like to create a similar indicator based on the High and Low of the day.  How would I create a similar indicator where I can pick stocks that have traded more than $1.5 from the low or high of the day (excluding gaps) on average of 15 days?

E.g.

AET, CEPH, COF, TIE

You can see that above stocks have traded for about $1.5 or more in a day excluding gaps.

Thanks

tony
