Scanning for Gaps in the Pre-Market with ThinkOrSwim

 

ThinkOrSwim’s built-in scans don’t allow you to scan for gaps in the pre-market, they only work after the open. Because of this, most traders are forced to pay huge monthly fees for premium scanners like Trade-Ideas or Pristine’s ESP scanner. So I developed these custom scans using TOS ThinkScript to help find the best stocks forming gaps in the premarket, using the free market data and scanning tools in the ThinkOrSwim platform.
