How to find spreads in the P2P.Army futures screener

The screener combines spot and futures from dozens of exchanges into pairs and sorts them by price spread. We read the table on real rows, the filters, the pair page and a checklist: why a 5% spread on a sub-cent coin is more often a trap than an opportunity.

The P2P.Army futures screener collects spot and perpetual futures prices from dozens of centralized exchanges and DEXs, pairs them up and sorts them by price spread. The table is part of the DEX/CEX plan; the strategy overview and FAQ on the landing page are free.

The screener table

Reading the EACCUSDT row

A long perp on Gate.io at 0.007221, a short on MEXC at 0.007620: a spread of +5.5255%. Funding is +0.015% per 4 hours, +0.09% a day. Lifetime is 0 minutes: the spread just appeared. On a coin worth less than a cent, five percent is a few price ticks and a thin book where the volume at the best prices may be tens of dollars.

Filters

  • Direction. Spot + Futures, Futures + Futures or Futures + Spot — what each means is covered in lesson 5.
  • Futures Markets. Only exchanges where you have an account; ALL / DEX / CEX quickly separates decentralized venues.
  • Filter by. Select by price spread or by funding with a from–to range. An upper bound helps drop obviously suspicious spreads.
  • Time until funding and Extras — as in the funding scanner: time until payment and pairs with different intervals. They do not affect pairs with a spot leg: spot has no funding.
  • Limit. How many rows to show.

The pair page

The chart button opens the pair page: leg cards with price, rate and quote update time (“Updated 5 sec. ago”; stale quotes are highlighted in red), the price spread and funding, a spread history chart, funding rate history and a step-by-step “How to earn on this pair” guide — which leg to open, where the income comes from and when to close. We covered how to read the spread chart in lesson 4 on the MOOUSDT pair.

Pre-entry checklist

  1. 1

    The spread holds rather than flickers

    Life time is hours, and the spread history shows a stable gap that can converge rather than chaotic jumps.
  2. 2

    There is order book depth

    Both exchanges have more volume at the needed prices than your position. Otherwise slippage eats the spread.
  3. 3

    Deposits and withdrawals are open

    Check the coin’s status on both exchanges’ deposit and withdrawal pages. A closed transfer is the main reason for “eternal” spreads.
  4. 4

    It is the same coin

    Compare the project name and token contract. Different projects with almost the same price sometimes share a ticker on different exchanges.
  5. 5

    Funding is not against you

    Negative net funding eats the spread every interval while you wait.
  6. 6

    The result after fees

    The spread minus four fees and a slippage buffer — lesson 7.

Frequently asked questions

What does the futures screener show?

Spot–futures and futures–futures pairs across exchanges with the price spread, net funding, time until payment and spread lifetime, and on the pair page — spread and funding history.

Why is a 5% spread on a little-known coin not ready profit?

Most often it cannot be captured: there is no volume in the book, deposits or withdrawals are closed on one exchange, or different coins trade under one ticker. Otherwise algorithms would close such a spread within seconds.

What does “0m” in the Life time column mean?

The spread just appeared. Such setups often disappear just as fast; the ones that hold for hours and are confirmed by spread history are more reliable.

How is the funding filter different from the spread filter?

The price spread filter selects pairs by the legs’ price difference — the screener’s main income. The funding filter selects by the net rate per interval, if funding is your main interest.
