RE: [amibroker] Code for volume of a stock in the top 50% of volume in the past 90 days

["Duke Jones, CMT" <Duke@xxxxxxxxxxxxx>]

Use Percentile 

>From the help file...

// Example 1: 
// show bars when 'current' Day Volume ranks within 
// TOP 30% of volumes of last 100 bars (is above 70th Percentile) 
Filter = Volume > Percentile( Volume, 100, 70 );
