What it is
An Inside Bar is a price consolidation pattern where a bar's entire range (high to low) is contained within the range of the previous bar. The previous bar is called the "mother bar" and the smaller bar is the "inside bar."
What it signals: After a strong move, the market pauses to consolidate. Volume often decreases during the inside bar as participants wait for the next move. This compression typically precedes an explosive breakout.
Inside bars are neutral patterns - they don't predict direction, only that a significant move is coming. Trade the breakout, not the pattern itself. The direction of the breakout determines whether you go long or short.
The psychology
The Inside Bar represents compressed energy waiting for release. The mother bar (Day 1) shows a wide range - buyers and sellers were active. Then the inside bar (Day 2) contracts entirely within that range. Both sides have paused, creating a coiled-spring setup.
The inside bar is a volatility contraction. After a wide-range day, the market needs to digest. Traders are waiting for new information, and the narrowing range builds potential energy. The breakout direction often produces a powerful move because all that compressed energy releases at once.
At key levels, inside bars become powerful decision points. An inside bar at resistance that breaks down suggests rejection. An inside bar at support that breaks up confirms the level. The mother bar defines the battlefield - the breakout declares the winner.
Identification
- 01Inside bar's high is lower than mother bar's high - Completely contained
- 02Inside bar's low is higher than mother bar's low - Fits within the range
- 03Clear mother bar - Day 1 should have a meaningful range
- 04Breakout direction determines bias - Pattern is neutral until the break
- 01Small inside bar relative to mother bar - Tighter compression = more energy
- 02At a key level - Support, resistance, or moving average confluence
- 03Multiple inside bars - 2-3 consecutive inside bars increase the coil effect
- 04Decreasing volume on inside bar(s) - Confirms the pause before expansion
- 01Inside bar is nearly the same size as mother bar - No real compression
- 02In choppy, trendless conditions - False breakouts are more common
- 03Low-volatility environment - Compression needs prior expansion to be meaningful
- 04Inside bar breaks both ways (whipsaw) - Wait for a clean close beyond the range
Execution framework
Place buy stop above mother bar high, sell stop below...
For breakout: Below the mother bar's low. For breakdown: Above the mother bar's high. The mother bar range defines the entire risk envelope.
T1: Measured move equal to the mother bar's range projected in the breakout direction. T2: Next support/resistance level. Inside bars at key levels with tight ranges produce the best setups.
Minimum 1:2. Smaller inside bars relative to the mother bar create tighter risk and better R:R.
Context matters
The Inside Bar is a versatile pattern that works as both a continuation and reversal signal depending on where it appears. The key is the volatility compression - energy contracts before it expands.
- 01At clear support or resistance levels
- 02After a strong trending move (continuation setup)
- 03Small inside bar relative to a large mother bar
- 04Breakout aligned with the higher timeframe trend
- 05Volume decreases on the inside bar, surges on breakout
- 06Multiple consecutive inside bars (tighter coil)
- 01In the middle of a choppy range
- 02Inside bar is nearly the same size as the mother bar
- 03Low overall volatility environment
- 04Against the dominant trend direction
- 05Breakout on low volume
- 06Frequent whipsaws in the same area
The mother bar defines your range. Break above for long, below for short. No break means no trade.
