SpreadLabs is a data and analytics platform for cross-exchange arbitrage on perpetual futures. We track funding-rate spreads, price spreads, and other exchange inefficiencies across multiple venues in real time — and we're continually adding new signal types as we identify them.
The dashboard ranks active opportunities by annualized return (Δ APR), with the long and short legs already worked out so you can read the trade directly. We provide the signal — you execute on your own venue of choice.
Current Spreads shows live, in-progress opportunities — pairs where the spread is open right now. These update every few seconds.
Finalized Intervals shows closed historical spread windows with their realized PnL — what you would have earned if you'd captured the spread, broken down into funding PnL and price PnL. This is the data you use to backtest your entry rules.
The Score (0–100) blends realized funding PnL, price stability of the underlying, liquidity (Sum OI and volume), and how cleanly the spread closed. Higher scores indicate intervals that would have been more reliably capturable in practice — not just lottery rows where the headline Δ APR was huge but liquidity was thin.
Full scoring formula is documented in Docs → Score methodology.
Currently 11 exchanges: Binance, Bybit, MEXC, Aster, Hyperliquid, Lighter, Apex, Backpack, EdgeX, Ethereal, and Extended.
More than 15 additional exchanges are coming soon — we're prioritizing them based on data quality, user demand, and venue liquidity. If there's a specific exchange you'd like to see prioritized, let us know.
Update frequencies depend on your plan:
The underlying exchange data freshness varies by exchange — most CEXs update funding rates every 1 minute and order book snapshots multiple times per second.
Free: 24 hours of finalized intervals, 2 days on the funding chart. Pro: unlimited finalized intervals, 90 days on the chart. Max: full history on both.
History depth varies by exchange depending on when we started ingesting their data — newer venues have shorter histories than long-established ones.
The Δ APR shown is gross — funding rate spread annualized, before fees and slippage. The Bid/Ask Spread column shows the cost of crossing the spread at a given notional (configurable: 1k / 10k / 100k / 1M).
For finalized intervals, PnL Total reflects realized funding income minus realized price drift, but does not include exchange fees. Plug in your maker/taker fees and slippage estimate to get a net number.
Annualizing very short funding intervals magnifies them. A 0.3% spread paid over a 1-hour funding cycle annualizes to ~2,628% APR — but you'd need that exact spread to persist for a full year to actually realize that return, which never happens.
Treat very high Δ APR as a flag for "look at this", not a return projection. Use Sum OI and Score to filter out illiquid or unreliable rows.
An API is in active development and will be available on the Max plan only when it ships. We're building both REST and WebSocket endpoints — same data the dashboard uses, with rate limits sized for production workflows.
If you want early access when the API is ready, email [email protected] and we'll add you to the beta list.
Yes. Pro and Max plans let you export Finalized Intervals and funding-rate history as CSV directly from the dashboard. Filter to the tokens, exchanges, and time range you care about, then download.
For programmatic access at scale, the API on Max (in development) will be the better fit — it lets you stream the same data into whatever notebook, database, or backtest harness you already use.
The dashboard itself has no per-user rate limits — browse, filter, and export as much as you want. Rate limits will only apply once the API ships on Max, and we'll size them generously for real production workloads.
Final API rate limits will be documented when the API enters public beta. If your use case needs a higher ceiling, we can discuss custom limits as part of a Max plan.
Anytime. No cancellation fees. If you cancel mid-billing-cycle, you keep Pro access until the end of the period you've already paid for, then drop to Free.
Within 7 days of an annual subscription purchase: yes, full refund, no questions asked. Email [email protected].
Outside that window we don't typically refund — but if you've genuinely been billed for a service you couldn't use (an outage, etc.), reach out and we'll make it right.
Credit card via Stripe (Visa, MC, Amex), and crypto (USDC, USDT on Ethereum, Arbitrum, and Solana) via our payment processor. Max plans can pay by wire.
No, and we never will. SpreadLabs is a data and analytics platform — we don't execute trades, route orders, or interact with your exchange accounts in any way. We only pull public market data (funding rates, mark prices, order books) which requires no authentication and reveals nothing about anyone's positions.
We do not collect, request, or store exchange API keys. There is nothing for an attacker to compromise on our side that could affect your trading accounts.
The minimum we need to run an account: your email address, your saved filters and watchlists, and basic usage events (which pages you visit, when you log in) for product analytics and capacity planning.
We do not store any trading data, positions, exchange credentials, or financial information. There's no way for SpreadLabs to know what trades you take based on signals you see — that happens entirely on your own infrastructure.
EU (Frankfurt) primary, with US (Virginia) failover. Encrypted at rest (AES-256) and in transit (TLS 1.3). We're SOC 2 Type II certified — full report available on request under NDA.
Yes. Settings → Account → Delete account. Your account, saved filters, watchlists, and personal data are permanently deleted within 30 days. We retain anonymized aggregate usage stats for service capacity planning.
Sign-in uses magic links — one-time email links that expire after use. No password to phish, no password to leak. For accounts that want an extra factor on top of email, TOTP (Google Authenticator, Authy, 1Password) is available on paid plans, and WebAuthn / hardware security keys (YubiKey) are available on Max.
