This public guide explains what the ByKaranteli data terminal covers, who it is for, and how the platform is structured: the recording network, the free data surfaces, and the member workspace built on top of them.
ByKaranteli is a crypto derivatives data terminal. Our own collection network records liquidations, funding, open interest, options, ETF flows and CFTC positioning around the clock, and the history is published free with provenance on every row. There is no signal engine and no forecast layer: the platform records what the venues did and shows it with its source and timestamp. The signal engine that used to run alongside the data was retired in September 2026; its pages now redirect to the data they were built on.
Behind the scenes, recorders subscribe to exchange websocket feeds for liquidations, order books and tickers, poll REST endpoints for funding and open interest, read Deribit for options, issuer pages for ETF flows, the CFTC for positioning, and our own Bitcoin node for network health. Every collector writes its freshness into a status row, and the public status page shows the age of every feed so a stale series is visible before anyone relies on it.
The platform's stated goal is transparency at a level aggregator sites rarely offer: published methodology per series, honesty labels that say how a number was derived, retention rules written down, and an immutable public record of every incident that touched a feed. Whether the data is valuable to you is a judgment only you can make, but you will not be making it in the dark.
ByKaranteli is designed for self-directed traders and researchers who work on crypto derivatives and want the underlying market data with its provenance rather than a black-box score. The ideal user is comfortable reading funding, open interest and liquidation tables, understands why a number's source matters, and can size positions using the Kelly-based risk guide. It is not a beginner's platform and it is not an automation. Every trade still needs to be placed manually in your broker account.
If you are new to crypto derivatives, read the risk guide and the methodology before signing up. Leveraged futures carry the risk of losing your entire position. Market data describes the past; it does not predict the future.
The public surface has everything you need to evaluate the platform before committing to a subscription. /data lists every free dataset with its coverage and download format. /symbols shows every tracked USDT perpetual with its recorded market state, and each ticker has its own page with funding history and pressure. /liqmap is the six-venue liquidation model with real prints overlaid. The methodology page explains how each series is collected; the risk guide helps you size positions responsibly.
When you are ready, create a free account and build a watchlist. The weekly digest will give you a feel for how the recorded data behaves on your symbols of interest before you commit further.
Three concrete things. First, we record the data ourselves from the venues instead of reselling an aggregator feed, so every row has a source and a timestamp. Second, we publish how each series is collected and label whether a number is measured, derived or modelled. Third, when a feed breaks we say so on the status page and in the incident log rather than quietly backfilling.
Traders and researchers who want crypto derivatives market data with its provenance: liquidations, funding, open interest, options, ETF flows and positioning, recorded continuously and published free. It is not a broker and not a signal service; you still execute trades in your own account at your own risk.
It did, until September 2026. The rule-based signal engine was retired and its pages, receipts and APIs now return a redirect or a 410 Gone status. The platform publishes recorded market data only, and no win rate or performance figure from the old engine is shown anywhere.
The recorders run 24/7 and write each value the moment it arrives. Pages read the same tables the public API serves, and the status page shows the age of every feed. You can pull the JSON or CSV endpoints yourself and compare them with the venue's own data.
Every USDT-M perpetual that Binance lists as TRADING has a symbol page with its recorded ticker, funding history and pressure score. Delisted contracts keep their historical rows. Spot-only pairs and non-USDT margined contracts are out of scope.
Yes. The /developers page documents the public JSON endpoints and the /data hub lists the CSV downloads. All are CORS-enabled with a short cache. No API key is required for the public tier; a hosted MCP endpoint serves the same data to AI assistants.
Your watchlist is preserved. You lose access to the member workspace, but your saved symbols remain and re-activate automatically when you renew. Paywall reminder emails (7d, 3d, 1d buckets) tell you the exact expiry date so you can plan.
