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.
Number of confirmed hourly candles. Warm-up history stays fixed; only this parameter changes.
Directional rule · long or cash
BUY when close first crosses above the previous candle’s upper band; SELL on the first cross below its previous lower band. Each candle is compared with its own previously known band. Confirmed closes only; cash start, no shorts/pyramiding. Fills no earlier than the next open with fees and slippage. Thresholds are analysis conventions, not optimized recommendations.
Shared capital and cost model
Includes the buy fee; the remainder stays in cash.
One adverse markup/markdown. Do not add spread a second time.
1 = next open. No retroactive trade at the signal close.
Preparing the calculation module. The shared market snapshot is already available.
Calculation and interpretation of the same candle
For breakout rules, the comparison channel must be known before the signal candle; a channel including the current candle instead describes its range.
Lower=min_lower_length(L); Upper=max_upper_length(H); Mid=(Lower+Upper)/2
Bands include the current closed candle; breakout rules must compare prior bands.
A breakout is no continuation guarantee. Window boundaries, current-candle inclusion and gap execution can fundamentally change results.

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.
