There are 2 types of screeners.
1 scans for daily statistics, like volume, range, up most, down most etc.
IB falls here, so do lots of packages tho. Prophetfinance java charts does this.
I consider this pretty elementary screening and you couldnt use it for intraday trade setups unless you watched each one.
The other type is the intraday setup scanner as found in tradeideas or realitytrader.
These are superior imo and more worth paying money for if you have to pay for your screener.
