Setup Description

This article details a counter-trend strategy designed to capitalize on the reversal that often follows the filling of an exhaustion gap. An exhaustion gap is a type of gap that occurs at the end of a strong trend and signals that the trend is losing momentum. The 'Gap Fill Reversal' strategy is based on the premise that once the exhaustion gap is filled, the market is likely to reverse and move in the opposite direction of the original trend.

This is a high-risk, high-reward strategy that is best suited for experienced traders who are comfortable with counter-trend trading. The key to success with this strategy is to be able to correctly identify an exhaustion gap and to have a strict set of rules for entry and exit.

Entry Rules

  1. Exhaustion Gap Identification: The first step is to identify an exhaustion gap. An exhaustion gap is characterized by a large gap in the direction of the prevailing trend, accompanied by a surge in volume. The gap should occur after a prolonged and extended trend.
  2. Gap Fill: The next step is to wait for the gap to be filled. The gap is considered to be filled when the price returns to the previous day's closing price.
  3. Reversal Signal: The entry is triggered by a reversal signal at the point where the gap is filled. This can be a candlestick pattern, such as a bearish engulfing pattern for a long trade or a bullish engulfing pattern for a short trade. It can also be a divergence on an oscillator, such as the RSI or the MACD.

Example:

A stock has been in a strong uptrend for several weeks. It gaps up to $120 from a previous close of $115 on high volume. This is a potential exhaustion gap. The stock then sells off and fills the gap at $115. At the $115 level, a bullish engulfing pattern forms on the 5-minute chart. This triggers a long entry.

Exit Rules

  1. Initial Stop Loss: The initial stop loss is placed on the other side of the reversal signal. For a long trade, the stop loss would be placed below the low of the bullish engulfing pattern. For a short trade, the stop loss would be placed above the high of the bearish engulfing pattern.
  2. Profit Target: The profit target can be set at a key support or resistance level, or at a multiple of the initial risk.
  3. Trailing Stop: A trailing stop can be used to lock in profits as the market moves in the trader's favor.

Example (continued):

In the example above, the entry was at $115. The low of the bullish engulfing pattern was $114. The initial stop loss would be placed at $113.90. The initial risk is $1.10. A 2R profit target would be at $117.20.

Profit Target Placement

  1. R-Multiples: Use a multiple of the initial risk (R) to set profit targets.
  2. Key Levels: Use key support and resistance levels from higher timeframes as profit targets.

Stop Loss Placement

  1. Reversal Signal: The most logical place for the initial stop loss is on the other side of the reversal signal.
  2. ATR-Based Stop: An ATR-based stop can also be used to provide a more dynamic stop loss.

Risk Control

  1. Max Risk Per Trade: Limit risk to 1-2% of the trading account per trade.
  2. Daily Loss Limit: Establish a daily loss limit of 3-5% of the trading account.
  3. Confirmation: This is a high-risk strategy. It is essential to have a clear and confirmed reversal signal before entering a trade.

Money Management

  1. Position Sizing: Use the position sizing formula to calculate the appropriate position size based on the risk per trade and the stop loss distance.
  2. Scaling: Scaling is not recommended for this strategy.

Edge Definition

The statistical edge of this strategy comes from the fact that exhaustion gaps are often followed by a significant reversal. By waiting for the gap to be filled and for a clear reversal signal, traders can enter the trade at a high-probability turning point. The win rate for this strategy may be lower than a trend-following strategy, but the winning trades can be significantly larger, resulting in a high profit factor of 2.0 or higher.
