A crypto arbitrage screener is a tool that takes every live price gap across exchanges and lets you filter and rank them by your own rules — minimum net profit, chosen exchanges, coin or market type — so only the opportunities actually worth trading show up on your screen.
At any moment there are thousands of price points moving across dozens of exchanges. Most of those gaps are too small, too illiquid, or eaten by fees. A screener's whole job is to cut that flood down to a short, sorted shortlist that matches what you can trade. This page explains, in plain language, what a screener does, how it differs from a scanner or a finder, which filters actually matter, and how to use ArbiScreen's free screener across 17 exchanges.
What a Crypto Arbitrage Screener Does
Every genuine screener does four jobs in sequence. The first three are the same as any scanner; the fourth — filtering to your rules — is what makes it a screener.
📡
Gathers live prices
Pulls the current price of each coin from many exchanges at once, refreshing every few seconds so nothing is stale.
🧮
Calculates net profit
Subtracts trading fees, withdrawal fees and network costs, so you see what you'd actually keep — not the misleading headline gap.
🔎
Filters to your rules
Hides everything below your minimum net %, outside your chosen exchanges, or in markets you don't trade — the core screening step.
🏆
Ranks the survivors
Sorts what's left by real profit so the best opportunities sit at the very top of the list.
The one rule beginners must remember
A 3% gap on the screen is not 3% profit. You pay a fee to buy, a fee to sell, and often a withdrawal fee to move the coin. A good screener filters on the number after all of that. Screen by net profit, never by the big gross percentage.
Screener vs Scanner vs Finder — What's the Difference?
These three words overlap heavily, and most good tools do all three. The difference is only one of emphasis, and knowing it helps you search smarter:
| Term | Emphasis | In one line |
|---|
| Scanner | Watching | Continuously sweeps the market in real time |
| Finder | Discovery | Surfaces gaps you didn't know existed |
| Screener | Filtering | Narrows the full list down to your criteria |
In practice ArbiScreen is all three at once — it continuously scans 17 exchanges, finds every live gap, and lets you screen them down to exactly what fits your capital. Whatever you call it, the goal is the same: turn a chaotic market into a clean, ranked shortlist.
The Filters That Actually Matter
A screener is only as good as its filters. These are the ones worth setting — the rest is noise:
💰
Minimum net profit %
The most important filter. Set a floor (say 0.5% after fees) so tiny, unprofitable gaps never reach you.
🏦
Exchanges you use
Only show gaps between venues where you actually hold accounts — a gap you can't trade is useless.
🧩
Market type
Spot spreads, spot-futures basis, funding-rate or geo premiums — screen for the kind of arbitrage you run.
💧
Liquidity & volume
Filter out micro-cap coins with thin books you can't fill or withdraw cheaply.
How to Screen for Your First Trade — Step by Step
1
Start with spot spreads, sorted by net profit
Spot is the simplest market. ArbiScreen shows it by default, ranked best-first.
2
Set a net-profit floor
Filter out anything below a sensible net % so you only look at gaps worth the effort and risk.
3
Limit to your exchanges
Screen to the venues you're funded on, so every remaining row is actually executable.
4
Check liquidity and the withdrawal network
Confirm there's real volume and a cheap, fast way to move the coin between the two exchanges.
5
Act fast or set an alert
Gaps close in seconds. Execute both legs promptly, or let the tool alert you when a fresh qualifying gap appears.

Frequently Asked Questions
What is a crypto arbitrage screener?▼
It is a tool that collects live price gaps across many exchanges, subtracts fees to show net profit, and then lets you filter and rank those gaps by your own rules — such as minimum net %, chosen exchanges or market type — so only the opportunities worth trading appear.
What's the difference between a screener and a scanner?▼
Very little in practice; the terms overlap. A scanner emphasises continuously watching the market, while a screener emphasises filtering the results down to your criteria. Good tools like ArbiScreen do both: scan 17 exchanges in real time and let you screen the gaps by net profit, exchange and coin.
Is there a free crypto arbitrage screener?▼
Yes. ArbiScreen's free tier lets you see and screen live arbitrage opportunities across exchanges with net-profit figures. Paid plans unlock the complete filtered list, all 17 exchanges and real-time alerts.
What should I filter by?▼
Filter first by minimum net profit after fees — that's the number that matters. Then limit the list to exchanges you actually use, the market type you trade (spot, futures basis, funding or geo), and coins with enough liquidity to fill and withdraw cheaply.
Does a screener place trades for me?▼
No. A screener shows and filters opportunities; you place the trades yourself on your own exchange accounts. That keeps your funds safe and gives you full control. Automated trading is a separate tool (a bot) with its own added risks.
Why screen by net profit instead of the biggest spread?▼
Because the biggest headline gap is often the least profitable once fees are removed — big gross spreads frequently sit on illiquid coins with high withdrawal costs. Screening by net profit surfaces gaps you can actually capture, not ones that look good but lose money.
