The bars
The squeeze
No squeeze: the bands are outside the channel; the last one fired 17 bars ago, up. Momentum leans up (the close is above the 20-bar average).
- After past squeezes
- 3 squeezes fired with 5 bars after: the price went on in the direction it fired 33% of the time, -0.19% on average that way. The size of the move 5 bars on was 1.17%, against 1.13% for any 5-bar stretch in these bars.
- How long they lasted
- Squeezes in these bars lasted 1 to 13 bars, 8 on average.
- Read it with care
- A squeeze says a bigger move is likely, not which way: the side it fires on is the clue, and it is wrong often. Wait for the fire, and keep the stop beyond the coil.
Half the width of the Bollinger bands (2 standard deviations) and of the Keltner channel (1.5 ATR), and the squeeze, on the last bars. The last bar is marked.

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
Volatility comes in waves: quiet spells give way to big moves. The squeeze spots the quiet. When the Bollinger bands, which widen and narrow with the standard deviation, shrink inside the Keltner channel, which follows the average true range, the market is unusually calm for its own range. When the bands push back out, the squeeze has fired, and traders look for the move to follow in the direction it fired.

Not advice. Arithmetic on the bars you type; a squeeze in the past bars does not say where the next move goes.
