The Inside Bar Strategy, Trading Compression

An inside bar is a candle whose high and low sit completely within the range of the previous candle. It signals compression: the market is pausing before choosing a direction.

The previous candle is called the mother bar. The inside bar is the baby inside it.

How to trade it:

1. Identify an inside bar on a higher timeframe such as the 4H or Daily, ideally at a key level or in the direction of the trend.
2. Mark the high and low of the mother bar.
3. Decide your plan: trade a breakout in the direction of the trend, or wait for a sweep of one side and a reversal.
4. For a breakout entry, wait for a candle body to close beyond the mother bar's high or low.
5. Place your stop on the other side of the mother bar, or at the midpoint for a tighter version.
6. Target the next key level, or a measured move equal to the mother bar's size.

Strengths:

- Clear levels
- Defined risk
- Works on many timeframes

Weaknesses:

- Frequent false breakouts
- Tiny mother bars produce poor reward-to-risk
- Ineffective in choppy markets

Tip: combine with liquidity thinking. Many inside bar breakouts fail first, sweeping one side, before the real move.

Test it on 30 examples before you trust it with real money.

On intraday timeframes the weakness about tiny mother bars is mostly a cost problem. An M15 mother bar of 6 pips on EURUSD, traded with the stop on the other side and a measured-move target, risks about 6 pips to make 6, and spread plus commission can take close to a pip off each side of that. The setup only becomes reasonable when the mother bar is several times the round-trip cost.

On the 4H and Daily, the timing of the inside bar matters as much as its shape. A Daily inside bar on a Friday or the day before a major release is often just a quiet day ahead of the event, not compression in any useful sense. I skip those.

The sweep-first tip at the end is the version I'd test first. On the 4H I've seen plenty of breaks of one side during the Asian session that reversed at the London open and then ran through the other side, which is exactly the false break you describe followed by the real one.

Inside bars on higher timeframes are a good compression signal. On lower timeframes they appear very often, so a filter improves quality: only trade inside bars at key levels or after a strong move, and skip those in the middle of a range.

The mother bar's size also matters. If it's very large, the stop beyond the mother bar becomes wide, and the risk/reward of the breakout may not be worth it.

PropScalpDesk's cost point is why I rarely bother with M15 inside bars now. With about a pip of round trip cost I want a mother bar of at least 15 pips, keeping cost under 7 percent of risk, which on EURUSD mostly means H1 or higher.

The version I like is in the chart, a made up H1 EURUSD sequence with a 22 pip mother bar at 21:00 London and an 08:00 close above its high that runs the full 22 pip measured move by 10:00. Overnight candles stay inside apart from a 3 pip wick below the low at 03:00, and with no body closing outside, the setup never broke.

I keep the original mother bar as the reference for the whole night rather than resetting it on every new inside bar. Resetting would have shrunk the range to a few pips by 02:00, and the cost problem comes straight back.

On stops I prefer the far side of the mother bar on H1, even though the midpoint version halves the risk. An 11 pip midpoint stop is easy to reach on an ordinary retest after a London break.

Does anyone trade that overnight wick as a sweep on its own? I have never found the reversal reliable enough before London.
