What is an inside bar? The mother bar and the inside bar

Two candles make the pattern. The mother bar is the larger first candle; the inside bar is the next one, with a lower high and a higher low. Some traders accept an equal high or low; stricter ones want the inside bar within the mother bar’s body. Pick one rule and keep it.

Candle colors do not matter; the contraction does. A big candle followed by a small one inside it says the market paused. Two or more inside bars in a row, all within the same mother bar, show an even tighter coil. Either way, the mother bar’s high and low are the levels that decide the trade.

Inside bar vs harami: what is the difference?

The harami is the candlestick version of the same idea, but it compares bodies: a small body inside a large one, with the wicks free to poke out. The inside bar compares whole ranges, wicks included, and ignores the bodies. A pair of candles can be both, either one or neither, as the drawing shows.

The difference matters for the stop. A harami’s small candle can wick beyond the first candle, so the pattern’s extremes are not always the first candle’s; an inside bar always has the mother bar’s high and low as its edges.

Inside bar and harami: the second candle’s range and body both sit inside, with the note range and body inside. Inside bar only: the mother bar has long wicks and a small body, and the second candle sits inside its range but above its body. Harami only: the second body sits inside the first body, but its wick pokes above the mother bar’s high, circled in red.

Where inside bars work best

On a busy 5-minute chart, inside bars appear dozens of times a day and most mean nothing. Filter them:

  • With the trend: an inside bar after a pullback in an uptrend, traded on the upside break. Read the trend on a higher timeframe, as in market structure.
  • At a level: the mother bar tests support, VWAP or yesterday’s high and the inside bar holds there, as in the key levels routine.
  • Tight: a small inside bar well within a large mother bar is a clearer pause than one nearly as big.
  • Not in the middle of a range, in the midday lull or just before scheduled news.

Entry: the break of the mother bar

There are three common triggers. A buy stop a few cents above the mother bar’s high fills as soon as price breaks it: the earliest entry, and the one that catches the most false breaks. Waiting for a candle to close above the high confirms the break but pays a worse price. A buy stop above the inside bar’s own high is the most aggressive, with less confirmation.

For shorts, mirror everything below the mother bar’s low. Some traders place a buy stop and a sell stop together and cancel one when the other fills; others trade only the side of the trend, which removes many false signals at the cost of some missed moves. The breakout trading strategy covers breakout entries in general.

Stop placement: three options

The stop goes on the other side of the pattern, and its exact place changes the size. With the same entry at $36.50 and a fixed $125 risk, the drawing below compares three choices. A tighter stop does not mean a smaller loss; it means more shares and more stop-outs. Whatever you pick, size from it with the position size calculator.

  • Under the mother bar’s midpoint, $36.27: the tightest, $0.23 of risk and 543 shares, but ordinary noise reaches it most often.
  • Under the inside bar’s low, $36.18: $0.32 of risk and 390 shares, the common middle ground.
  • Under the mother bar’s low, $36.08: the widest and most structural, $0.42 of risk and 297 shares.

Right, a table for a 125 risk, shares = 125 ÷ risk: 1, under the mother’s midpoint, 36.27, risk 0.23, 543 shares; 2, under the inside bar, 36.18, risk 0.32, 390 shares; 3, under the mother’s low, 36.08, risk 0.42, 297 shares. Note: tighter stop, more shares, more stop-outs.

Targets in R

Measure targets in R, multiples of the risk. Common choices are a fixed 2R, the next level if it comes first, or the mother bar’s range projected from the breakout. With a $0.32 risk, 2R sits $0.64 above the entry.

Check the room before you enter: if the next level is closer than about 1.5R, skip the trade. Some traders take half off at 1R and move the stop to breakeven, which cuts full losses but also cuts the winners. Whatever you choose, test it in a trading journal.

False breaks and the fakey

Inside bar breaks fail often. The classic failure: price breaks the mother bar’s high, fills the buy stop, then closes back inside the mother bar’s range. Decide in advance that a close back inside ends the trade; exiting there usually costs less than the full stop.

Some traders then look the other way. When price breaks one end of the mother bar, closes back inside and later closes beyond the opposite end, the pattern is often called a fakey: it traps the breakout traders, and their exits can fuel the move. It is still only a setup, with the same stop and size rules. See false breakout for the general case.

Two panels with the same mother bar (36.10 to 36.48) and inside bar. In the false break, exit panel, the next candle wicks to 36.56, filling the buy stop at 36.50 (dot), then closes back inside at 36.38, marked with a red cross and the word exit. In the fakey, the other side panel, after the same false break, price closes below the mother bar’s low at 36.02 and a sell triangle prints.

Intraday vs daily inside bars

On the daily chart an inside bar, often called an inside day, is rarer and carries more weight: a whole session spent inside the previous one. Stops are wider, so positions are smaller, and an overnight gap can jump the stop and fill it far beyond its price. Day traders often use a daily inside bar as context: its high and low become levels for the next session, and a break of either can start a trend day.

On 5- and 15-minute charts, inside bars are frequent and noisy. Ignore them in the first minutes after the open, when candles are huge, and in the midday lull, when they are tiny, and check that the spread is small next to the stop. The best timeframe for day trading lesson shows how the timeframe changes stops and size.

Worked example: an inside bar after a pullback (hypothetical)

XYZ is a made-up stock in an uptrend on the 1-hour chart. On the 5-minute chart it rallies to a high of the day at $37.20, then pulls back to support near $36.10. A mother bar prints from $36.10 to $36.48, and the next candle stays inside it, from $36.20 to $36.40. There is room above: the high of the day is $0.70 from the planned entry.

  1. Entry: a buy stop at $36.50, two cents above the mother bar’s high. The next candle fills it.
  2. Stop: $36.18, two cents under the inside bar’s low. Risk: $0.32 a share.
  3. Target: 2R, $36.50 + $0.64 = $37.14, just under the $37.20 high of the day.
  4. Size: a $25,000 account risking 0.5% accepts $125; $125 ÷ $0.32 = 390 shares, about $14,235 of stock.
  5. Result: 390 × $0.64 = $249.60 (+2R) at the target; 390 × $0.32 = $124.80 (−1R) at the stop, plus costs.
  6. False break: if the breakout candle instead closes back inside the mother bar at $36.38, the plan exits there: 390 × $0.12 = $46.80, about −0.4R.
