How to Read Arbitrage Signals

An arbitrage signal is not a command to trade. It is a structured alert that the same or similar market is priced differently across venues. Reading it well means moving from left to right: symbol, route, market type, net spread, liquidity, funding and timing.

What this guide covers

  1. 1

    A signal is not a guarantee

    The scanner finds opportunities faster than manual checking, but it does not promise a profit.

  2. 2

    Symbol and route

    First read which coin is involved and the route: where the first leg opens, where the second leg opens, and in which direction.

  3. 3

    Market type and net spread

    Check whether the setup is spot-to-spot, futures-to-futures, or spot-to-futures.

  4. 4

    Liquidity, volume and timing

    The last checks are practical.

1

A signal is not a guarantee

The scanner finds opportunities faster than manual checking, but it does not promise a profit. It shows that a price difference exists right now. The trader still confirms execution quality and risk before opening a position.

  • A signal shows a price difference, not a guaranteed result.
  • Fast alerts still need a manual sanity check.
  • The goal is a tradable setup, not the biggest number on screen.
2

Symbol and route

First read which coin is involved and the route: where the first leg opens, where the second leg opens, and in which direction. The route tells you which exchange is the buy side and which is the sell side.

  • Confirm the symbol is the same asset on both venues.
  • Read the first leg and second leg exchanges.
  • Understand the direction of each leg before anything else.
3

Market type and net spread

Check whether the setup is spot-to-spot, futures-to-futures, or spot-to-futures. Then compare the raw spread with net spread. A large visible spread can still be poor after fees, slippage and depth.

  • Spot, futures and mixed setups behave differently.
  • Raw spread ignores fees, funding and slippage.
  • Net spread is the number that decides if a trade is worth it.
4

Liquidity, volume and timing

The last checks are practical. Look at 24h volume, order book depth around your size, funding direction and next funding time. These decide whether the visible spread survives real execution.

  • Thin depth can erase the spread on a normal-sized order.
  • Low 24h volume is a warning sign for execution and exit.
  • For funding-linked signals, check funding direction and next funding time.

Signal reading checklist

Walk each signal through the same order every time so nothing important is skipped.

  • Symbol is the same underlying asset on both venues.
  • Route and direction of both legs are clear.
  • Market type is identified: spot, futures or mixed.
  • Net spread stays positive after fees and slippage.
  • Liquidity and volume support your intended size.

Reading mistakes to avoid

  • Trading on raw spread without checking net spread.
  • Assuming two similarly named tokens are the same asset.
  • Ignoring order book depth and 24h volume.
  • Missing the next funding time on funding-linked signals.
  • Treating an alert as a signal to enter without any confirmation.

Reading arbitrage signals FAQ

Does a signal mean I should trade immediately?

No. A signal reports a price difference. You still confirm net spread, liquidity, fees and timing before deciding.

What is the most important number on a signal?

Net spread after fees and slippage matters more than raw spread. A smaller net spread with deep liquidity often beats a large raw spread on a thin book.

Why check the route and not just the coin?

The route tells you which exchange is buy and which is sell, and whether the legs are spot or futures. Without it you cannot judge the trade.
