What percentage of current price does Average True Range represent?
Normalizes ATR by the current close and scales the ratio as a percentage.
One dataset, the same parameters and the same candle for application and explanation.
BTCUSDC · confirmed hourly candles
Snapshot retrieved: 11 Oct 2026, 15:52 UTC · stored snapshot · background refresh scheduled · age when opened: 3,136 min
11 Sept 2026, 15:00 — 11 Oct 2026, 15:00 UTC · 720 evaluation candles · 3000 earlier candles for warm-up only. Your opened snapshot stays fixed. A visit can refresh a stale cache in the background for later visitors; fetching fresh is not a tick stream.
Parameters and precise application
Number of confirmed hourly candles. Warm-up history stays fixed; only this parameter changes.
Explicit formula parameter of the calculation convention described below.
Measurement and diagnosis · no trading direction
Inspect the actual value at each confirmed candle. This analysis produces no buy or sell orders.
Preparing the calculation module. The shared market snapshot is already available.
Calculation and interpretation of the same candle
The relative scale helps compare different price levels; a price distance requires explicit conversion back into USDC.
NATR = scalar·ATR/Close
TA-Lib C standard; null during warm-up. No claim of parity with a deployed unCoded engine.
NATR contains no direction and is not itself an absolute stop distance. Equal values do not imply identical loss distributions.

The sources support definitions and methodological limits. They do not establish profit for this specific BTCUSDC rule. This analysis is descriptive; parameter trials on the same history are not independent out-of-sample evidence. Parity with a deployed unCoded engine is not claimed.
