Guy did an analysis of this setup in his article titled "Fading the Gap"
From his article we learn the following historical statistics from the sample period he used...
- "On average 76% or three quarters of all gaps close at some point during RTH."
- Gaps on Monday were the least likely to fill and Thursday gap openings the most likely.
- Opening gaps up to 7 ES points in size were filled during the session at least 70% of the time. This probability drops off surprisingly quickly above the 7 ES point range.
Given these basic concepts as a foundation, I thought it might be helpful to use this topic for further discussion, analysis and trading ideas.
