Introduction

The Broadening Formation, also known as the Megaphone pattern, is a sign of increasing volatility and disagreement between buyers and sellers. This pattern is characterized by diverging trendlines, with both higher highs and lower lows. For the swing trader, the Broadening Formation presents unique opportunities to profit from this expanding price range. This article will provide a detailed methodology for trading this pattern on the daily chart, with a focus on capturing swings within the formation.

Entry Rules

There are two primary ways to trade the Broadening Formation. The first is to trade the swings within the pattern. A buy entry is triggered when the price touches the lower trendline and forms a bullish reversal candlestick pattern, such as a hammer or a bullish engulfing pattern. Conversely, a sell entry is triggered when the price touches the upper trendline and forms a bearish reversal candlestick pattern. The second method is to trade the breakout from the formation. A breakout occurs when the price closes decisively above the upper trendline or below the lower trendline. A buy or sell order is placed on the breakout, with a confirmation of a retest of the broken trendline.

Exit Rules

When trading the swings within the formation, the exit target is the opposite trendline. For a long position, the exit is at the upper trendline. For a short position, the exit is at the lower trendline. When trading the breakout, the exit target is a measured move equal to the height of the formation at its widest point. This measured move is projected from the breakout point.

Profit Targets

Profit targets should be set in terms of R-multiples. When trading the swings within the formation, a target of 2R to 3R is realistic. When trading the breakout, the target can be significantly higher, potentially 5R or more, depending on the strength of the breakout and the subsequent trend.

Stop Loss Placement

When trading the swings within the formation, the stop-loss should be placed just below the low of the entry candlestick for a long position, and just above the high of the entry candlestick for a short position. When trading the breakout, the stop-loss should be placed just inside the formation, below the breakout level for a long position, and above the breakout level for a short position.

Position Sizing

Due to the increased volatility of the Broadening Formation, it is prudent to use a smaller position size than usual. A risk of 0.5% to 1% of the trading account per trade is recommended. The position size is calculated as follows: Position Size = (Account Size * Risk per Trade) / (Entry Price - Stop-Loss Price).*

Risk Management

The Broadening Formation is an inherently risky pattern to trade due to the expanding volatility. It is important to be disciplined with stop-loss placement and position sizing. Avoid trading this pattern in illiquid stocks or during times of extreme market stress. It is also important to be aware of the potential for false breakouts, which are common with this pattern.

Trade Management

Once a trade is live, it is important to manage it actively. When trading the swings within the formation, consider taking partial profits at the midpoint of the formation. When trading the breakout, trail the stop-loss to lock in profits as the trend develops. A moving average or the Parabolic SAR can be used to trail the stop-loss.

Psychology

Trading the Broadening Formation can be a nerve-wracking experience. The expanding price swings can be emotionally challenging to handle. It is important to have a solid trading plan and to stick to it. A trading journal can be a valuable tool for tracking your performance and identifying any psychological weaknesses that may be affecting your trading. It is also important to be patient and to wait for high-probability setups. Do not force trades in this volatile environment.
