The inside bar

An inside bar is a candle whose whole range sits inside the range of the candle before it. The larger candle is called the mother bar, and the inside bar is read as a pause: a session in which price did not manage to go anywhere new. Traders watch the high and low of the mother bar as the levels to beat, but the break can go either way.

What defines an inside bar

The rule is simple: the high of the inside bar must be lower than the high of the mother bar, and the low of the inside bar must be higher than the low of the mother bar. The body of the inside bar can be anywhere within that range, and the body of the mother bar does not matter. What matters is the range: the inside bar is a smaller range entirely contained by the larger range before it.

A near miss is not an inside bar. If the high of the second candle is equal to the high of the first, the rule is not met, and the pattern is not flagged. The same applies to the low. The site's written rule is strict because a pattern that is almost there is a different thing from a pattern that is there, and the site does not want a reader to think a near miss is an occurrence.

The numbers behind the rule: rule IB-1 needs a mother bar whose range is at least 1.5 ATR, where ATR is the average true range of the last 14 sessions, and then a bar with a high below the mother's high, a low above the mother's low, and a range of at most 60 percent of the mother's range. It counts as formed when the inside bar closes.

What the pattern is supposed to mean

The inside bar is read as a pause. The previous candle moved price to a new high or low, and the inside bar shows a session in which neither buyers nor sellers managed to push price beyond that range. It is a contraction of volatility, and many traders expect a breakout from the mother bar's range to follow. The breakout can go either way: above the mother bar's high or below the mother bar's low.

A breakout above the high is read as a sign that buyers have taken control, and a breakout below the low is read as a sign that sellers have taken control. But the inside bar itself does not tell which way the break will go. It only shows that price paused. The break, when it comes, is a separate event, and the inside bar does not predict its direction.

The levels to watch

Traders watch the high and low of the mother bar as the levels to beat. A move above the mother bar's high is a break to the upside, and a move below the mother bar's low is a break to the downside. These levels are not targets; they are triggers. Some traders place orders just beyond them, expecting that a break will continue in the same direction as the breakout.

Other traders wait for the breakout to happen and then watch how price behaves after it. A break that quickly reverses back inside the range is a failed break, and it may be read as a sign that the pause will continue. The levels are the same for everyone, but what a trader does with them is a personal decision, and this site does not tell anyone what to do.

Where the pattern fails

The inside bar often appears in quiet markets, and a breakout may never come. Price can drift sideways for many bars, with each new bar inside the previous one, and a trader who expects a breakout may be disappointed. The pattern does not say when the break will come, and it does not say how far it will go. A break can also be small and quickly reversed.

A failed break is common: price moves just beyond the mother bar's high or low and then snaps back inside the range. That can trap traders who entered on the break. The pattern describes what price has already done; it does not predict what it will do next.

What the chart under the heading shows

The chart under the heading is an inside bar on gold futures (GC=F). The mother bar is the session of 4 January 2019, from a low of 1,275.30 dollars an ounce to a high of 1,294.20, a range of 18.90. The next session, 7 January, traded between 1,286.60 and 1,286.80, a range of 0.20, entirely inside the mother bar and far under the 60 percent the rule allows.

A word of caution about this example. It is the cleanest of the 145 that rule IB-1 found by the rule's own measure, and the cleanest by that measure is the one with the smallest inside range, here a bar that barely moved. A bar that narrow is a feature of how the source printed that day, and a reader should not take it as a typical inside bar. Most of the 145 are inside bars with real, if smaller, ranges.

Patterns describe, they do not predict

An inside bar is a description of what price has already done: a candle that stayed inside the range of the candle before it. It is not a forecast of what price will do next. The pattern does not say that a breakout will happen, and it does not say which way the breakout will go. It only says that price paused.

A reader who sees an inside bar on a chart should read it as a pause, not as a signal. The pattern is a useful way to see where price has contracted, but the next move is not written in the pattern. The pattern describes; it does not predict.

What the count says

Over ten years of daily bars rule IB-1 found 145 inside bars: 22 on the iShares MSCI Philippines fund (EPHE), 57 on the PLDT ADR (PHI) and 66 on gold futures. An inside bar needs only a mother bar of 1.5 ATR and a bar inside it with 60 percent of its range, so it is a common thing, and a common thing says little by itself.

The counts differ by instrument, and the page does not try to explain why. They are counts of separate occurrences; they say nothing about what followed any of them.

The mother bar is not always the previous session

An inside bar is defined relative to one larger candle, usually the one immediately before it. That larger candle is often called the mother bar, but the term can mislead. In a fast market, the mother bar might be several sessions back if the intervening candles were small or doji-like. Traders who anchor only to the previous session may miss a valid inside bar that is contained by a strong candle from two days earlier.

When watching a chart, look for any candle whose high and low sit completely within the range of a clearly larger candle. That larger candle need not be the last one. The key question is whether the market has compressed after an expansion. If it has, the inside bar is present, and the break from that compression is what matters.

A fake break often starts with a wick

The inside bar resolves when price trades beyond its high or low. Many traders place orders just outside those levels, expecting a clean move. But a break that starts with a long wick poking through the level and then closing back inside is a common failure. The wick shows that one side tried to push and was rejected within the same session.

A more reliable break is one where the candle closes beyond the inside bar's range, not merely touches it. Waiting for the close reduces the number of signals but filters out many false starts. For a pattern that already describes a pause, the close is the market's own confirmation of intent.

The inside bar does not need a doji

A common mistake is to think an inside bar must be a doji or a very small candle. The definition only requires that the high is lower than the mother bar's high and the low is higher than the mother bar's low. The inside bar can still have a substantial range, closing near its own high or low. It can look like a decisive candle on its own.

When an inside bar has a wide range and closes near its high, it suggests buyers were active within the larger consolidation. The market did not simply pause; it tested the upper part of the mother bar's range without breaking it. This is different from a quiet inside bar that sits in the middle of the range and shows no commitment.
