Inside Bar: What the Pattern Actually Shows
An inside bar is a candle that fits entirely within the previous one: its high is lower and its low is higher. In our sample of 400 daily EUR/USD bars it appeared 73 times, and the next day closed higher in 45% of cases against a base rate of 44%.
How the inside bar is defined
The definition is strict and leaves no room for interpretation: the current bar's high is below the previous high and its low is above the previous low. Body size is irrelevant — an inside bar can be a full-bodied candle or nearly a doji. That unambiguity is what makes the pattern useful for formal rules: it cannot be seen where it is not.
What happens inside the pattern
An inside bar means compression: the market failed to move beyond yesterday's boundaries in either direction. Both sides paused, the range narrowed, and pending orders accumulated on both sides of the previous candle. Hence the popular reading as preparation for a move. But a pause by itself says nothing about which way the exit will go.
Entry and stop placement
The classic approach is not to guess the side but to work from the fact of the breakout: pending orders beyond the mother bar's boundaries, stop behind the opposite edge. The advantage is that the stop distance is known in advance and equals the mother bar's range. The drawback is that a wide mother bar produces a wide stop, forcing a much smaller position.
What the measurement showed
The formal definition was run over 400 daily bars of EUR/USD (2025-06-16 to 2026-07-20). Any result has to be compared against the sample's base rate of up days, which is 44%, not against half.
- Inside bar: 73 occurrences, next day closed higher in 45%
The measurement shows exactly what you would expect from a pause pattern: the share of up days after an inside bar practically matched the sample's base rate. In other words it predicts no direction on its own and works only as a way to structure an entry, with boundaries and a stop known in advance.
The inside bar is one of the few patterns frequent enough for the measurement to mean anything at all: seventy-odd cases in four hundred bars. Even that is not enough to conclude anything about an edge. The figures describe one sample and one instrument rather than a property of the pattern in general — why that distinction matters is set out in our piece on sample size. The data is open and the method is in how we run backtests.
