Keltner Channels in Crypto: Why the Value Changes Before Candle Close

Keltner Channels set bands at a multiple of ATR around an EMA. ATR's Wilder smoothing makes the bands slower to react intrabar than Bollinger Bands.

Short answer

Keltner Channels = EMA(20) ± k × ATR(10), with k often 2. On the live bar, the EMA moves by α × price change and ATR changes through the live bar's true range, smoothed with weight 1/10. A sudden move therefore widens Keltner bands less, and more slowly, than Bollinger Bands, so intrabar breaks of Keltner bands are more likely to survive to the close — but still aren't final. Judge breaks on closed bars.

Which part of Keltner Channels uses the live bar

ComponentUses current bar?Effect intrabar
EMA(20) middleYesα ≈ 0.095
Live true rangeYesGrows
ATR(10)Yes1/10 weight
BandsYesWiden slowly

Compared with standard deviation, ATR reacts linearly and with Wilder smoothing, so Keltner bands are steadier inside a bar.
