What is Inside bar?

An inside bar is a candle whose entire high-to-low range fits inside the range of the candle before it, called the mother bar. It marks a pause — the market has stopped expanding and is coiling, often just before it moves again.

The definition is purely mechanical: the current candle's high is lower than the previous candle's high, and its low is higher than the previous candle's low. The larger preceding candle is called the mother bar. Nothing about colour or body size matters — only containment.

What it signals is a contraction in range. After a strong candle, an inside bar says the market has stopped making new ground in either direction; buyers and sellers have reached a temporary truce. Because range tends to alternate between expansion and contraction, that pause frequently precedes another expansion, which is why traders treat the mother bar's high and low as the trigger levels: a break above one or below the other resolves the pause.

Context determines how it's read. An inside bar partway through a strong trend usually reads as a continuation pause. One that appears after an extended run, at a major level, can instead mark the point where momentum stalled for good. Several inside bars in a row is a tight coil and often precedes a larger move.

The second candle's entire high-to-low range sits within the mother bar's. Range contracting after a strong move is a pause — the break of the mother bar is what traders act on.

For example

A stock rallies hard, printing a candle from $43.00 to $46.00. The next candle trades only between $43.80 and $45.40 — entirely inside the previous range. Two sessions later price closes above $46.00, breaking the mother bar's high, and continues to $50.

Why it matters to you

An inside bar gives you two exact, pre-marked levels — the mother bar's high and low — before anything happens. That's genuinely useful: you can set alerts, plan both directions, and enter on a break with a stop at the other side of a range that is by definition narrow. Small risk on a defined trigger is the whole appeal.

⚠ A pause is not a direction

An inside bar tells you the market is coiling, not which way it will uncoil. Traders routinely assume it must continue the prior trend and get caught when it breaks the other way. Treat it as a two-sided trigger, and be aware that on lower timeframes inside bars appear constantly and most resolve into nothing.

Frequently asked questions

What is an inside bar?

It's a candle whose high is below the previous candle's high and whose low is above the previous candle's low — the whole range is contained within the prior candle, called the mother bar. It signals a pause in the market's expansion.

How do you trade an inside bar?

The usual approach is to treat the mother bar's high and low as trigger levels: buy a break above the high or sell a break below the low, with a stop at the opposite side. Because the inside bar's range is narrow, the risk is small and well defined.

Is an inside bar bullish or bearish?

Neither by itself — it's a neutral pause. Direction comes from context: an inside bar inside a strong uptrend usually reads as a continuation pause, while one after an exhausted run at a major level can mark a stall. The break resolves it.

What's the difference between an inside bar and an outside bar?

They're opposites. An inside bar is contained within the previous candle's range, showing contraction. An outside bar engulfs the previous candle — a higher high and a lower low — showing expansion and a volatile, two-sided fight.
