# Inside bar

`inside_bar`

A bar whose range sits within the previous bar's range.

## Inputs

| Name | Type | Default | Range |
| --- | --- | --- | --- |
| allow_equal | bool | true |  |

## Outputs

| Name | Kind |
| --- | --- |
| inside_bar | event |
| in_a_row | value |

Warm-up: 1 bars (1 at the defaults).

Repaints: No.

## Formula

body = |close - open|, range = high - low, upper wick = high - max(open, close), lower wick = min(open, close) - low

high <= the previous high and low >= the previous low (strictly with equal values off); both bars have a range

in_a_row = how many inside bars in a row end at this bar, 0 on a bar that is not one

A bar whose high equals its low, or that has a missing price, is never part of a pattern. Computed on the prices the bars are drawn with: on Heikin-Ashi or Renko bars those are the built candles.
