The bars
The narrow range check
The last bar is not a narrow-range bar: its range, 25.10, is wider than at least one of the 3 bars before it. The bar before was an NR7 and an inside bar, and the last bar broke both its high and its low.
- The levels
- There is no squeeze on the last bar to trade. The last bar ran from 2,421.10 to 2,446.20.
- How quiet
- The last bar's range is 89% of the average range of the last 20 bars (28.15).
- In these bars
- There were 7 NR7s: the next bar broke its high or low 7 times, and its range averaged 0.9× the 10 bars before; and 14 inside bars: the next bar broke its high or low 13 times, and its range averaged 1.1× the 10 bars before. A handful of cases proves nothing on its own, but it shows how this market has behaved.
- Read it with care
- A narrow bar says a bigger move is likely, not which way. Breakouts fail often, so many traders wait for the break and keep the stop on the other side of the bar.

Education only, not investment advice. The answer comes from the numbers you typed in, not from your account or the market. Simulated results are hypothetical and have limits: real trading has slippage, gaps, changing results and emotions. Trading leveraged products can lose money quickly, including all of it.

Quiet before the move
Toby Crabel found that a very narrow day tends to be followed by a wider one. An NR7 is a bar whose range, high minus low, is the narrowest of the last 7 bars; an NR4 the narrowest of the last 4. An inside bar sits wholly within the bar before it. All three say the same thing: the market has gone quiet, and quiet rarely lasts.
