Crypto funding and basis, cost-aware and risk-scored

Funding and basis trades, priced after every cost.

The scanner finds market-neutral carry trades across major venues and shows what is left after fees, slippage and spreads, with data-quality checks and risk scores on every row. It is a data tool: no custody, no execution, no advice.

Net APR after every cost

Each opportunity is priced after trading fees on both legs, slippage for your trade size against the order book, and the entry spread. You see what is left, not the headline funding rate.

Data-quality gates

Stale quotes, legs taken seconds apart, crossed books, prices that disagree between venues and broken funding intervals are rejected before anything is ranked. A row you see passed every check.

Risk scores

Stability of funding over the last week, liquidity from depth and volume, venue tier and a composite score with published weights, so a high APR on a thin, erratic market does not look like a good trade.

How it works

  1. Step 1

    Collect

    Spot, perpetual and futures quotes, order-book depth and funding rates stream in from major venues.

  2. Step 2

    Check

    Every leg passes the data-quality gates: fresh, consistent across legs, sane prices, a valid funding schedule.

  3. Step 3

    Price

    Fees, slippage and spreads are subtracted at your trade size and holding period to give net profit, net APR and break-even time.

  4. Step 4

    Rank

    Stability, liquidity and venue risk are scored. You review the trade and, if you act, you do it yourself on your own exchange accounts.

How net APR is computed

For a trade of size S held for H hours, the scanner estimates:

  • Income: the funding you would collect over H hours at today's rate, plus the entry spread you lock in when the two legs are priced apart.
  • Costs: taker (or maker) fees for opening and closing both legs, and slippage for filling S against the order book depth of each venue.
  • Net profit = income − costs, in dollars.
  • Net APR = net profit ÷ S, scaled from H hours to a year. On leveraged legs the scanner also shows the return on the capital you would actually post.
  • Break-even = the hours of funding needed to pay back the costs. Shorter is safer: there is less time for funding to change.

Spot → Spot and Basis have no funding: their income is the price gap between venues or the futures premium that converges by expiry.

The estimate assumes funding stays at today's level for the whole holding period. Funding changes every interval and can turn negative, so treat net APR as a way to compare opportunities, not as a forecast.

Five strategies, in plain language

Each is a tab in the scanner. Your plan decides which tabs are open.

Spot → Perp

The trade
Buy the coin on spot and short its perpetual future for the same amount.
You earn
The funding payments that shorts receive while funding is positive. Price moves cancel out between the two legs.
Watch out for
Funding can fall or turn negative; the short perp needs margin and can be liquidated if price spikes.
Open Spot → Perp →

Perp → Perp

The trade
Go long the perpetual where funding is low and short it where funding is high, usually on two venues.
You earn
The difference between the two funding rates.
Watch out for
Both legs are leveraged, funding schedules differ by venue, and the gap can close quickly.

Spot → Spot

The trade
Buy where the coin is cheaper and sell where it is dearer.
You earn
The price gap per round trip, after both venues' fees and an estimate of withdrawal costs.
Watch out for
Transfers between venues take time; the gap can vanish before your coins arrive.
Open Spot → Spot →

Basis

The trade
Buy spot and short a dated future that trades at a premium.
You earn
The premium, which shrinks to zero as the future approaches expiry.
Watch out for
The premium can widen before it converges, and capital is tied up until expiry or exit.
Open Basis →

Funding extremes

The trade
A watchlist of single perpetuals whose funding is unusually high or low.
You earn
Nothing on its own: it is a signal. Hedge it with one of the other strategies before acting.
Watch out for
Extreme funding often reverts quickly and tends to come with volatile prices.

Questions

›Is this investment advice?

No. The scanner is a market-data and analytics tool. It does not know your situation, does not recommend trades and does not promise returns. Every figure is an estimate.

›Do you hold my funds or place trades?

No. There is no custody and no execution, and we never ask for your exchange API keys. If you act on an opportunity, you do it yourself on your own exchange accounts.

›What does net APR mean here?

The annualized return on the trade's notional after fees, slippage and the entry spread, at the trade size and holding period shown. It assumes funding stays where it is for the holding period, which it often does not.

›Why can a high funding rate show a low or negative net APR?

Because costs come first. Fees on four fills, slippage on thin books and a wide entry spread can use up weeks of funding, especially for short holding periods or large sizes.

›What do I get for free?

The free plan opens the scanner without a card and, when signed out, without an account. The live preview above is exactly what it shows, and the plan comparison lists what every plan includes, straight from the plan catalog.

›How do I pay?

Paid plans are prepaid. Where online payments are open, the Billing page takes USDC or USDT on supported networks; otherwise our team assigns plans on request.

›Can I use the data in my own product?

Only on a plan that includes commercial-use rights, and only as the acceptable use policy allows. Personal plans are for your own analysis.
