An inside bar is a candle whose entire range, wicks included, fits inside the previous candle's high and low. That larger previous candle is called the mother bar. The pattern shows the market compressing: buyers could not reach the prior high and sellers could not reach the prior low. It is neutral on its own, so traders wait for a close outside the mother bar.

Measure wick tip to wick tip
You need two candles. The first, the mother bar, is usually wide. The second is the inside bar: its high sits below the mother bar's high and its low sits above the mother bar's low. Compare the tips of the wicks. Bodies don't enter into it.
Color doesn't matter either. A red inside bar, a green one and a doji all qualify, as long as the full range stays contained. In the diagram, a strong green mother bar is followed by a smaller red candle whose upper wick stops short of the prior high and whose lower wick stays above the prior low. That is the whole test.
Two edge cases come up constantly:
- Equal highs or lows. Strict definitions reject a candle that ties the mother bar's high or low. Many traders accept it. Pick one rule and apply it every time, or your notes on which setups worked stop meaning anything.
- Several inside bars in a row. Sometimes two or three small candles all print within the same mother bar. The mother bar stays the reference until price closes outside it.
Shaping candles by hand in Alphacent's Build a Candle tool trains your eye on where each wick ends, which is what this check depends on.
What the pause says about buyers and sellers
The mother bar records a wide fight in which one side moved price a long way. The next candle is quieter. Buyers could not get back to the high, sellers could not get back to the low, and the range contracts.
A contracting range doesn't say who will win. What it does give you is two reference lines, the mother bar's high and low, that traders on both sides are now watching. A breakout through either one is often where the next move starts.
Context adds a tilt. After a strong green mother bar in an uptrend, a small inside bar more often reads as buyers resting than as sellers taking over. The breakout still has to confirm it.
Telling it apart from a harami or spinning top
The inside bar and the harami overlap, which is why beginners mix them up.
A harami compares bodies. The second candle's body sits inside the first candle's body, and its wicks are allowed to poke out. An inside bar compares full ranges, wicks included. So a candle can be a harami but not an inside bar (its upper wick pierces the mother bar's high), or an inside bar but not a harami (the mother bar has a thin body and long wicks, and the second body sits up in the wick area).
The usual reading differs too. The bullish harami and bearish harami are treated as early reversal hints after a trend, typically with the second candle in the opposite color. The inside bar is neutral, and traders use it for both continuation and reversal setups.
The candles in the diagram happen to satisfy both definitions: the red body sits inside the green body, and the whole red candle sits inside the green range.
One more lookalike: an inside bar often has a small body and looks like a spinning top. A spinning top is judged on its own shape. An inside bar only exists relative to the candle before it.
Where inside bars earn your attention
Most inside bars are noise. The ones worth watching usually have some of these traits:
- They follow a strong directional candle in a clear trend. A pause after a thrust is the classic continuation setup.
- The mother bar sits at an obvious level. A mother bar that tested a prior high or a well-used floor gives the breakout something to prove. See support and resistance for how those levels form.
- They appear on a higher timeframe. A daily inside bar compresses a full day of trading. On the 1m chart they print constantly. The timeframe changes what the pattern is worth.
- The breakout carries volume in the direction of the prior trend.
Confirmation means a candle closing beyond the mother bar. A wick poking through doesn't count.
Why so many inside bar breakouts fail
In a choppy sideways market inside bars print constantly, and each "breakout" is just price wandering to the other side of the range.
Low timeframes make it worse. False breakouts are routine on short charts, where a single burst of orders can push one candle past the mother bar before it fades. Try this in Alphacent's simulator: pick one market, count the inside bars in the last couple of months of daily candles, then check how many broke out and kept going. With Pro, repeat it on the last few hours of 1m candles and compare.
The clearest failure is a reclaim: price closes above the mother bar's high, then the next candle falls back inside the range. Many traders read that as the setup being wrong and exit.
The mistakes behind most losses:
- Trading every inside bar without checking the prior trend.
- Entering in the middle of the inside bar instead of waiting for the breakout close.
- Ignoring the mother bar's size. A huge mother bar means a wide stop, which means a small position or no trade.
A hypothetical long on a $2,000 paper account
Say an ETF has been trending up on the 1H chart. The mother bar runs from a low of $50.80 to a high of $52.40. The next candle is an inside bar with a high of $52.10 and a low of $51.30. The candle after that closes at $52.60, above the mother bar's high. You enter at $52.60 and risk 1% of $2,000, which is $20.
There are two common stop placements, and the position size follows from whichever you choose:
- At the inside bar's low, $51.30. Risk per share is $52.60 minus $51.30, or $1.30. $20 divided by $1.30 is about 15.4, so round down to 15 shares. That is a $789 position with a maximum loss of $19.50.
- At the mother bar's low, $50.80. Risk per share is $1.80. $20 divided by $1.80 is about 11.1, so 11 shares. That is a $578.60 position with a maximum loss of $19.80.
The dollar risk barely changes. The wider stop gives the trade more room and buys fewer shares, which is the whole idea behind position sizing. With the tighter stop, a 2:1 target sits twice the $1.30 risk above entry: $52.60 plus $2.60, or $55.20.
All prices here are invented for the arithmetic, and a fast market can fill a stop below its level, so the real loss can run slightly past the planned $20.

Questions people ask
Is an inside bar bullish or bearish?
Neither by itself. It shows contraction, not direction. Traders read it in the context of the trend before it: after a strong rally it is usually treated as a possible continuation, and the breakout direction decides the trade. A close below the mother bar's low in an uptrend is a warning, not a buy.
What timeframe is best for trading inside bars?
Higher timeframes such as the daily and 4-hour charts tend to give cleaner signals, because each candle holds more trading and fewer random spikes. Inside bars on 1-minute and 5-minute charts appear so often that most of them mean little. Whatever you choose, test it on paper first.
What is an inside bar fakey?
A fakey is an inside bar setup that breaks out of the mother bar, fails, and closes back inside its range. Some traders treat that failed breakout as a signal in the opposite direction, reasoning that the traders caught on the wrong side will have to exit. It still needs context to mean anything.
