Fading Pre-Market Partial Gaps in ES Futures Using VWAP Rejection
Setup Description
This strategy is a mean-reversion setup designed for the E-mini S&P 500 (ES) futures market. It aims to capitalize on the tendency of partial gaps to fill during the regular trading session. A partial gap occurs when the opening price of the current session is outside the previous session's closing price but within the previous session's range. The core of this strategy is to fade the initial gap direction, anticipating a move back towards the previous day's close. The entry trigger is a rejection off the Volume-Weighted Average Price (VWAP), which acts as a dynamic level of support or resistance.
This setup is most effective in a market environment that is not strongly trending. In a range-bound or choppy market, the probability of a gap fill is significantly higher. The strategy is based on the principle that the pre-market gap is often an overreaction to overnight news or events, and that the market will tend to revert to its mean once the initial flurry of activity has subsided.
Entry Rules
- Partial Gap Confirmation: The ES futures contract must open with a partial gap. This means the opening price is above the previous day's close but below the previous day's high (for a gap up), or below the previous day's close but above the previous day's low (for a gap down).
- Initial Drive and VWAP Test: After the market opens, there is often an initial drive in the direction of the gap. The strategy requires waiting for the price to pull back and test the VWAP. For a gap up, the price will pull back to test the VWAP from above. For a gap down, the price will rally to test the VWAP from below.
- VWAP Rejection: The entry is triggered by a clear rejection off the VWAP. This can be identified by a candle that touches the VWAP and then closes strongly in the opposite direction of the gap. For a gap up, this would be a bearish candle closing below the VWAP. For a gap down, this would be a bullish candle closing above the VWAP.
- Confirmation: The rejection candle should be confirmed by a follow-through candle in the same direction. This provides additional confirmation that the market is likely to continue in the direction of the fade.
Example:
ES futures closed the previous day at 4500. The next morning, it opens at 4510, which is a partial gap up. The price rallies to 4515 in the first 15 minutes of the session and then pulls back to test the VWAP at 4512. A bearish candle forms that touches the VWAP and closes at 4510. A subsequent candle closes at 4508. This would trigger a short entry.
Exit Rules
- Initial Stop Loss: The initial stop loss is placed just above the high of the rejection candle for a short trade, or just below the low of the rejection candle for a long trade. This is the logical point of invalidation for the setup.
- Profit Target: The primary profit target is the previous day's closing price. This is the point at which the gap is considered to be filled. A secondary profit target can be set at a key support or resistance level beyond the previous day's close.
- Time-Based Stop: If the trade has not reached its profit target by the end of the trading session, it should be closed out. This is an intraday strategy, and holding positions overnight is not recommended.
Example (continued):
In the ES example, the entry was at 4508. The high of the rejection candle was 4513. The initial stop loss would be placed at 4513.25. The primary profit target is the previous day's close of 4500.
Profit Target Placement
- Previous Day's Close: As mentioned, the primary profit target is the previous day's close. This is the most logical and high-probability target for a gap-fill trade.
- Key Levels: Other potential profit targets include key support and resistance levels, such as pivot points, Fibonacci levels, or previous day's value area high/low.
- Measured Moves: A measured move can also be used to project a profit target. The initial leg of the move from the open to the high/low of the session can be measured and then projected from the entry point.
Stop Loss Placement
- Rejection Candle High/Low: The most logical place for the initial stop loss is just above the high of the rejection candle (for shorts) or just below the low of the rejection candle (for longs).
- VWAP: A more aggressive stop loss can be placed on the other side of the VWAP. However, this increases the risk of being stopped out by a minor fluctuation.
- ATR-Based Stop: An ATR-based stop can also be used to provide a more dynamic stop loss that adapts to market volatility.
Risk Control
- Max Risk Per Trade: Limit risk to 1-2% of the trading account per trade.
- Daily Loss Limit: Establish a daily loss limit of 3-5% of the trading account.
- Market Environment: This strategy is most effective in non-trending markets. Avoid using this strategy in strongly trending markets, as the probability of a gap fill is lower.
Money Management
- Position Sizing: Use the position sizing formula to calculate the appropriate contract size based on the risk per trade and the stop loss distance.
- Scaling: Scaling in and out of positions can be used to manage risk and maximize profits. For example, a trader could take partial profits at a key support/resistance level before the gap is fully filled.
Edge Definition
The statistical edge of this strategy comes from the tendency of partial gaps to fill in the ES futures market. This is a well-documented phenomenon that is driven by the mean-reverting nature of the S&P 500. The VWAP rejection provides a high-probability entry trigger that helps to filter out false signals. The win rate for this strategy can be in the range of 60-70%, with a profit factor of 1.5 or higher.
