The bars
The channel
The last close sits inside the channel, 59% of the way up. The channel runs from 2,266.77 to 2,355.42 around a 20-bar average of 2,311.09.
- The width
- 2 × an ATR of 22.16 each side: 3.84% of the price.
- Squeeze
- The Bollinger bands sit inside the channel: a squeeze. The market is quieter than its usual range, and quiet spells can end with a bigger move, in either direction. Bollinger bands: 2,268.64 to 2,350.39.
- Read it with care
- Some traders follow a close outside the channel, others fade it back to the middle; neither works every time, so the stop and the size matter more than the signal.

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.

Bands from the range, not the closes
The Keltner channel puts an exponential average of the closes in the middle and sets the edges a multiple of the average true range away. Because the ATR measures the whole bar, gaps included, the channel widens and narrows more smoothly than Bollinger bands, which are built from the spread of the closes alone.
The two together give the squeeze: when the Bollinger bands shrink inside the Keltner channel, the closes are calmer than the bars' usual range. Compare them with the Bollinger bands calculator, measure the range with the ATR calculator and size the trade with the position size calculator.
Not advice. Arithmetic on the bars you type; a channel describes the past bars, not the next one.
