Inside Bar Breakout: Trading Volatility Contraction
The Logic of the Squeeze: What is an Inside Bar?
The Inside Bar (also known as a 'Harami' in Japanese candlestick charting) is a 2-candle pattern where the second candle is completely contained within the high and low range of the first candle (the 'Mother Bar'). This represents a classic state of Volatility Contraction or a temporary pause in market direction.
Think of the Inside Bar as a 'Spring' being compressed. The market has moved aggressively, and now it is catching its breath as buy and sell orders reach temporary equilibrium. This contraction almost always leads to a violent expansion of volatility—a breakout—in one direction or the other.
Identifying the Mother Bar and the Squeeze
- The Mother Bar: A large, trending candle that establishes the initial range. 2. The Inside Bar: A smaller candle whose high is lower than the Mother Bar's high, and whose low is higher than the Mother Bar's low. A truly powerful setup is the Multiple Inside Bar, where two or three consecutive bars are nested inside each other, signaling an extreme consolidation.

Strategy: Trading the Breakout Confirmation
The Signal Entry: The primary entry occurs when the price breaks above or below the range established by the Mother Bar. A buy stop is placed at the Mother Bar's high, and a sell stop at its low. This allows you to 'Capture' the volatility expansion regardless of which side finally wins the battle. Trend Alignment: Inside bars are most powerful when they act as Continuation signals. If the market is in a strong uptrend and forms an inside bar, the probability of an upward breakout is much higher than a reversal.
Platform Optimization: Setting Buy/Sell Stops
Because the breakout can be fast and occur during news events, professionals use Pending Orders (Buy Stop / Sell Stop) to ensure they are filled instantly when the 'Dam breaks'. This prevents 'Chasing' the move after it has already accelerated. Most professional traders place their orders 2-3 pips beyond the extremes of the Mother Bar to avoid 'Wick-hunting' noise.
