Philosophy & Institutional Market Mechanics
Gaps occur when an asset opens significantly higher (Gap Up) or lower (Gap Down) than the previous day's close due to overnight news, global market movements, or quarterly earnings reports. Gap traders categorize gaps into four distinct types: 1) Common Gaps (filled quickly), 2) Breakaway Gaps (start of massive new trends, rarely filled), 3) Runaway/Measuring Gaps (mid-trend acceleration), and 4) Exhaustion Gaps (end of a trend).
Gap strategies split into two proven models: 1) The "Gap and Go" model (buying when price holds above the opening gap high on heavy volume), and 2) The "Gap Fade / Gap Fill" model (shorting a gap-up when price fails to sustain above the opening range and breaks below the 15-minute low, targeting a full fill back to the previous day's close).
Overnight Imbalance Liquidity: Gaps trap overnight position holders. When an opening gap fails to find follow-through buying, trapped buyers panic sell, creating rapid, high-probability moves back toward the previous close.

Step-by-Step Trade Execution Blueprint
Follow this systematic 4-phase checklist from pre-market screening to profit extraction.
Determining Gap Type at 09:15 AM
Classify the opening gap size. Gaps > 0.5% in major indices or > 1.5% in stocks are candidates. Check if the gap breaks a major multi-week resistance (Breakaway) or opens inside an existing range (Common).
Waiting for 09:30 AM Range Formation
Mark the high and low of the first 15-minute candle (09:15 - 09:30). Do not place trades during the first 5 minutes of opening chaos.
Setting Immediate Protection
Execute long on ORH break with stop loss placed below ORL. For Gap Fills, execute short on ORL break with target at Previous Day Close.
Intraday Gap Target Rules
Gap trades move swiftly in the morning session (09:30 - 11:30 AM). Book 50% at 1:2 R:R and close all intraday positions by 03:15 PM.

Non-Negotiable Risk & Stop-Loss Guidelines
Professional traders survive and compound because they protect downside capital with mechanical discipline.
Never allocate more than this percentage of total portfolio equity on any single execution.
For Gap-and-Go: Stop loss placed below the opening 15-min candle low. If ORL breaks, the continuation thesis is completely invalidated.
Trail stop along the 5-min 9 EMA.
Stop trading if the market becomes choppy and fills only 50% of the gap before reversing.
- •Never trade huge opening gaps (>3% on stocks) at market open without a 15-minute confirmation
- •Beware of option premium decay if trading gaps with Out-of-the-Money Options
- •Always check for corporate results or regulatory news announcements

Fatal Mistakes to Avoid
Why it happens: A dangerous retail myth. Powerful Breakaway Gaps on earnings never fill and can rally +15% in a single day, bankrupting gap-fade short sellers.
Rule Fix: Only fade a gap if price breaks the opening range low with heavy selling volume.
Why it happens: Emotional FOMO before algorithms and institutional liquidity stabilize.
Rule Fix: Enforce the mandatory 15-minute wait rule.

Frequently Asked Questions
Q1.Do all market gaps eventually get filled?
No. While common gaps in range-bound markets fill roughly 80% of the time, "Breakaway Gaps" and "Runaway Gaps" in powerful bull markets may not fill for months or years.
Q2.What is the Opening Range Breakout (ORB) strategy?
ORB is a classic gap trading strategy where a trader measures the high and low of the first 15 or 30 minutes and executes in the direction of the breakout with a stop at the opposite end of the range.
