A crypto arbitrage finder is a tool that automatically searches every exchange for the same coin selling at two different prices — and hands you a ready list of gaps worth trading, ranked by real profit.
'Finding' an arbitrage opportunity by hand means opening a dozen exchange tabs, comparing prices coin by coin, and doing fee math faster than the market moves — which no human can do. A finder automates the search: it scans thousands of price points across exchanges every few seconds and only surfaces the gaps that still pay after costs. This page explains how a finder works, how it differs from a scanner or screener, and how to use one to find your first real opportunity.
Finder, Scanner, Screener — What's the Difference?
These words overlap a lot, and most good tools do all three. But the emphasis differs, and knowing it helps you search smarter:
| Term | Emphasis | In one line |
|---|
| Finder | Discovery | Surfaces opportunities you didn't know existed |
| Scanner | Continuous watching | Constantly sweeps the market in real time |
| Screener | Filtering | Narrows a big 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 by net profit, exchange or market type. Whether you call it a finder, a scanner or a screener, the job is the same — turn a chaotic market into a clean, ranked list of tradable opportunities.
How a Crypto Arbitrage Finder Works
1
Collect prices everywhere
It pulls the live price of each coin from many exchanges at once, refreshing every few seconds so nothing is stale.
2
Compare every pair
For each coin it finds the cheapest and most expensive venue and measures the gap between them.
3
Subtract the costs
It deducts trading fees on both sides, plus withdrawal and network fees, to reveal the net profit — the only number that matters.
4
Rank and present
It sorts what's left by real profit and shows the best opportunities first, so you don't dig through noise.

What a Good Finder Must Find
A gap between two spot exchanges is only one kind of opportunity. A complete finder looks across every form of arbitrage so you never miss an edge:
💱
Spot spreads
The same coin cheaper on one exchange than another — the classic buy-low-sell-high gap.
🔁
Funding-rate extremes
Perpetual contracts paying an unusual funding rate you can harvest market-neutral.
📈
Spot-futures basis
A wide gap between a coin's spot and futures price — the cash-and-carry setup.
🌍
Geo premiums
A coin priced higher in a specific country's market, like the ZAR, TRY or INR premium.
Manual Finding vs an Automated Finder
| By hand | With a finder |
|---|
| Exchanges you can watch | 2–3 realistically | 17 at once |
| Speed | Minutes per check | Every few seconds |
| Fee math | Manual, error-prone | Automatic, net figure shown |
| Opportunities missed | Most of them | Very few |
| Result | Exhausting, unreliable | A clean ranked list |
The takeaway: manual finding is fine for learning the concept, but you cannot compete on speed or coverage. The market simply moves faster than a person can compare prices. A finder levels that playing field.

Find Your First Opportunity — Step by Step
1
Open the finder and sort by net profit
Start with spot spreads sorted highest-first. The top rows are your best candidates.
2
Pick a liquid coin
Choose a well-known coin with real volume on both exchanges so you can actually fill your order and withdraw cheaply.
3
Verify the net figure
Confirm the profit-after-fees number is worth your time, and sanity-check the price on each exchange.
4
Check the withdrawal network
Make sure there's a fast, cheap network to move the coin between the two venues — or pre-fund both to skip the transfer.
5
Execute and record
Buy the cheap side, sell the expensive side quickly, then log your real net result to learn what works.

Frequently Asked Questions
What is a crypto arbitrage finder?▼
It is a tool that automatically searches many exchanges for the same coin trading at different prices and gives you a ranked list of profitable gaps. It collects live prices, compares every pair, subtracts fees to show net profit, and sorts the results so the best opportunities appear first.
What's the difference between an arbitrage finder and a scanner?▼
Very little in practice — the terms overlap. 'Finder' emphasises discovering opportunities, 'scanner' emphasises continuously watching the market, and 'screener' emphasises filtering. Good tools like ArbiScreen do all three: continuously scan, find every gap, and let you screen by your criteria.
Is there a free crypto arbitrage finder?▼
Yes. ArbiScreen's free tier lets you see live arbitrage opportunities across exchanges with net-profit figures immediately. Paid plans unlock the complete opportunity list, all 17 exchanges and real-time alerts.
What kinds of opportunities can a finder detect?▼
A complete finder detects spot spreads (same coin cheaper on one exchange), funding-rate extremes on perpetual contracts, spot-futures basis gaps, and geo premiums where a coin is priced higher in a specific country. ArbiScreen covers all four.
Can a finder guarantee I'll make money?▼
No. A finder shows you where real, net-of-fee gaps exist, but your actual profit depends on execution speed, liquidity, and how quickly you complete both legs before the gap closes. It removes the searching and the math; the trading is still up to you.
Do I need to install a crypto arbitrage finder?▼
Not with a web-based one. ArbiScreen runs in any browser on phone or computer, so there's nothing to download and the data is always live. You simply open it and the current opportunities are already there, ranked by net profit.
