Not every exchange pair is good for arbitrage. Two venues may list the same symbol, but one may have low liquidity, high fees, unstable funding data or frequent maintenance. The best exchange is the one where the trade can be executed and closed reliably.
Liquidity and order book depth
A good arbitrage exchange has enough depth to fill your size without heavy slippage.
Fees and market coverage
Reasonable taker fees and VIP tiers affect net profit directly.
Funding quality and contract design
For futures, check funding intervals, mark price behavior, liquidation rules and whether the contract is linear USDT, inverse or settled differently.
Deposits, API and operational risk
Stable deposits and withdrawals, reliable market data and dependable APIs matter as much as the percentage on screen.
A good arbitrage exchange has enough depth to fill your size without heavy slippage. Depth matters more than a single large spread, because a spread you cannot execute has no value.
Reasonable taker fees and VIP tiers affect net profit directly. Coverage matters too: an exchange that lists the pairs and contract types you trade gives you more usable opportunities.
For futures, check funding intervals, mark price behavior, liquidation rules and whether the contract is linear USDT, inverse or settled differently. Small differences in contract design change the real risk.
Stable deposits and withdrawals, reliable market data and dependable APIs matter as much as the percentage on screen. Before using a new exchange, test small trades and see how it behaves during volatility.
Before trusting a venue for arbitrage, confirm it can execute and settle reliably.
Enough depth to execute your size, reasonable fees, stable deposits and withdrawals, clear contract specs and reliable data. Operational reliability matters as much as the spread.
Not on its own. A large spread on an illiquid or unreliable venue can be impossible to execute or exit. Reliability usually beats a bigger raw number.
Start with small trades, confirm fee tiers, check deposits and withdrawals, and if you use tools, verify API stability before committing size.
