Has the breakout been accepted by the market?

Pick an instrument and a past session date. I'll check whether price accepted (held) beyond the prior session's value area, or rejected back inside (a fakeout), with an estimated buy/sell delta for confirmation.

FAQ
Q.01

What assumptions and edge cases does this calculator use?

Choose binance or bybit, a completed UTC session before today, a timeframe of 1m, 5m, 15m or 30m (default 15m) and a value area rule from 0.5 to 0.9 (default 0.70). If you paste candles, each must be consistent (high at or above low, open and close, and low at or below them); a session with no candles is an error. Not covered: order flow beyond the candles, other venues, and any statement about what price will do. It describes the session and is not a signal.

Q.02

What does "accepted" mean here?

Price didn't just briefly poke beyond the prior session's value area, it held there long enough, with enough follow-through, to be treated as a real move rather than a wick. An unaccepted break is a candidate for a fakeout: a reversal back inside value.

Q.03

What is the estimated delta, and how accurate is it?

Cumulative buy vs. sell volume estimated from each candle's OHLCV (open/high/low/close/volume), not from real tick-by-tick trade data. It's a supporting signal, included by default, that can be disabled: acceptance is decided primarily from price behavior around the value area boundary.

Q.04

Which exchanges and instruments does this support?

Binance and Bybit perpetual futures. Pick any date up to yesterday (UTC).

Q.05

How is this different from Open Analysis and Session Structure?

Open Analysis looks at how the session began; Session Structure classifies the whole session's shape. This tool answers one narrower, tactical question: for a specific break beyond value, did it stick? It's the tool to reach for once you already suspect a breakout is underway.
