Today I’ve released updated versions of the All-In-One Gap Scan and the % and $ Gap Columns.
The improvements to the columns were just to fix a small error I found. But for the scan, several big improvements have been implemented …
- Choose both min/max gap % size
- Choose both min/max gap $ size
- Choose whether you only want to scan for gaps that haven’t filled yet
- Choose whether the gap needs to be “significant” — i.e., gapping above the prior high, or below the prior low (completely outside the range of the prior day’s candle)
- Choose whether the gap needs to be a “pro” or “tier 1” or “shock” gap — i.e., gapping over a prior day red candle, or gapping under a prior day green candle, adding “shock value” to the gap
This single all-in-one scan works during the extended hours / premarket / aftermarket, and continues working as the regular trading hours begin, so you only need to use one scan all day long.
The other change is that the $ and % values are now all calculated from the prior close instead of the high/low, just for consistency, and whether the gap is over/under the prior day’s candle is specified as a separate criterion in settings, which can be turned on/off at will. This will help keep things consistent and logical no matter what type of trading you do.
Premarket Gap Scanner for ThinkOrSwim:
This video shows how to customize the volume, average volume, price ranges, and average true range / ATR parameters for my Pre-market Gap Scanner package for ThinkOrSwim.
Every trader is different, and we each focus on different types of stocks. Maybe you like playing opening drive momentum trades on low-float stocks early in the morning. Maybe you’re looking to play the first pullback on a trend day. Or maybe you’re looking for 1-2-3 patterns on 2 and 5 minute charts.
All of these plays might require different volume, average daily volume, and average true range requirements when you’re scanning for gaps in the pre-market. So this video will walk you through how to change and customize those settings in ThinkOrSwim, without having to do any coding in Thinkscript.

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.
