Gold Interday Gap Strategy

A gap occurs when gold opens at a different price than it closed the prior session. GLD trades only 9:30 AM to 4:00 PM ET while gold futures trade nearly around the clock, so the GLD open reflects overnight global moves. GC futures gap mainly over weekends and around major releases. The opening price reflects overnight global moves creating a visible gap on the chart between the prior close and the current open.

Most gaps fill because they represent temporary price inefficiency. The market did not trade through those prices and tends to return to previous close through mean reversion. Small gaps fill 70-80 percent of the time as they typically represent normal overnight flow rather than significant events.

For gap down fill trade buy near the open within first 15 minutes. Set stop below the gap low with small buffer. Set target at previous day close. This profits if price rises back to fill the gap. Exit if price falls below stop indicating gap extension.

Focus on small gaps of 0.3-0.5 percent which have highest fill probability of 70-80 percent. Medium gaps of 0.5-1.0 percent are tradeable but selective. Large gaps above 1.0 percent have only 30-40 percent fill rate and should not be automatically faded.

Exit if the stop is hit indicating gap extension. On day trades exit by 3:00 PM ET if the gap is not filling. If the gap shows no progress by early afternoon consider a time-based exit. Do not hold a losing day trade hoping for a late fill.

At 9:00 AM ET check the GC gold-futures price versus the prior close. Calculate the percentage change to estimate the expected gap and where the session will open. There is no currency component to adjust for in US trading. Assess how GC moved whether gradual or sharp to evaluate gap quality.

Gaps into support or resistance have higher fill probability as levels provide defense. Gap down into support finds buyers at that level aiding fill. Gaps through levels are potential breakaways with lower fill probability. Use levels for stop placement and target adjustment.

Key filters include gap size 0.3-1.5 percent, no major news catalyst, gap against prevailing trend, gap into support or resistance, and avoiding Friday. Score each filter and require minimum 3-4 out of 5 for trade. Higher filter scores correlate with better win rates.

Hold overnight only if the gap has partially filled showing progress, no major events are expected overnight, and the position is sized appropriately for overnight margin. Move from day-trade to overnight (initial/maintenance) margin, set a stop for overnight protection, and reassess at the next open. Exit same day if no progress.

Track win rate overall and by gap size, profit factor, average win and loss, win rate by direction gap up versus down, and win rate by day. Target 55 percent plus win rate and 1.5 plus profit factor. Use statistics to adjust filters and position sizing for different gap categories.

Define precise rules for gap identification, filters, entry, exit, and sizing. Backtest on 5 plus years of data. Calculate win rate and profit factor by category. Validate on out-of-sample data ensuring similar performance. Test robustness across different market conditions. Target profit factor above 1.5.

Long call for gap down fill and long put for gap up fill provide defined risk. Spreads reduce cost for moderate conviction. Straddles capture either fill or continuation for large uncertain gaps. Options eliminate stop slippage risk and allow safe overnight exposure.

Island reversal has gap in one direction followed by gap in opposite direction. Price becomes isolated like island between two gaps. This is powerful reversal signal. Island top gap up then gap down is bearish and island bottom gap down then gap up is bullish. Trade in direction of second gap.

Exhaustion gap occurs after extended trend 5 plus days representing final push with high fill probability so fade it. Breakaway gap occurs at pattern breakout representing trend initiation with low fill probability so do not fade. Context and location determine gap type.

Allocate 10-15 percent of portfolio to gap strategy. Lower than trend strategies due to opportunistic nature. Gold should be 50-60 percent of gap allocation. Maximum 1.5 percent risk per trade. Be aware of other strategy positions to avoid conflicts when gap aligns with existing position.
