What it looks like
Inside bar breakout
An inside bar is a two-candle formation. The study requires a breakout confirmed by the third candle.
An inside candle stays within the mother candle range, and the following candle closes beyond one of the mother candle boundaries.
A wick beyond the boundary is not enough: the breakout candle must close outside the mother range.
Exact machine rule
The inside candle remains within the mother candle range; the following candle must close beyond one of the mother candle boundaries.
The mother candle fixes both boundaries before the breakout candle is evaluated.
Optional practice
Check your recognition
Select the chart where the formation is already complete.
Try it
A dotted candle is still forming; a solid candle is closed. Only one chart contains a completed signal.
The exercise checks recognition. Historical outcomes are calculated separately and do not promise a price move.Three features of Inside bar breakout
Signal and boundary
The inside candle remains within the mother candle range; the following candle must close beyond one of the mother candle boundaries.

A wick beyond the boundary is not enough: the breakout candle must close outside the mother range.
Similar formations and limits of one example
An inside bar describes containment; direction is known only from the later confirmed close. The shape identifies an event to research. It does not predict the next move or provide a trading signal by itself.
One formation does not establish the probability of a move. The historical comparison measures outcomes against a comparable background for each configuration.
