About Bull Curve
Bull Curve records the BCH Bull premium market over time and turns it into historical charts, curves, comparisons and alerts.
The BCH Bull premium tracker shows what is quoted now. Bull Curve keeps those observations, so you can see how a premium compares with its own history, how it has moved, and where it sits across expiries and contract sizes.
What we collect
- Premium quotes
- Every configuration BCH Bull quotes (asset, position, contract size, duration, leverage or protection), recorded on a fixed interval. 1,080 configurations are currently tracked.
- BCH price
- Signed attestations from three General Protocols oracles: BCH/USD, BCH/EUR and BCH/BTC. The USD attestation nearest each premium snapshot is stored with it, so a premium can be read against the price at the time it was quoted.
- The raw response
- The untouched upstream payload is stored alongside the normalized data. If the upstream schema changes, history can be re-derived from the original bytes rather than lost.
How to read a premium
Bull Curve uses one convention everywhere:
- +3.25%: the trader receives 3.25% of the contract size as premium.
- −1.70%: the trader pays 1.70%.
Changes between premiums are stated in percentage points. A move from 3.0% to 4.0% is +1.0 percentage point, not a 33% increase.
Where history begins
Premium history starts when our collector first ran, on 23 Aug 2026. Earlier premiums are not reconstructed or estimated. Where we have no observation, we say so.
A historical percentile describes how a premium compares with the observations we hold for that exact configuration. It is withheld until there are enough of them to mean anything, and it is never a claim about future profitability.
BCH price history reaches further back. Every General Protocols oracle signs its prices into a public relay, the one Oracles.cash reads, and that relay keeps every message an oracle has ever signed. We walked each of the three oracles back to its first attestation and stored what it signed, so nothing there is reconstructed either.
Relationship to BCH Bull
Bull Curve is an independent analytics product. It is not operated by, or affiliated with, BCH Bull or General Protocols.
Bull Curve does not execute contracts and never holds funds, seed phrases or private keys. Where a quote maps cleanly onto a BCH Bull contract, we link to it with the parameters exactly as quoted.
