SpreadScan is a real-time tool for finding arbitrage opportunities in crypto markets. The platform aggregates data from 17 exchanges, calculates real spreads accounting for fees, and shows network withdrawal availability — all in one place.
This guide walks through every section of the platform and shows how to get the most from each tool.
Quick Start: What to Do in the First 5 Minutes
Step 1: Go to spreadscan.com and register — core features are available for free.
Step 2: Open the Spreads section — the main screen with real-time cross-exchange spreads.
Step 3: Look at the table. Columns left to right:
- Pair — trading pair (e.g., ETH/USDT)
- Buy Exchange — where it's cheaper
- Buy Price — ask on the buying exchange
- Sell Exchange — where it's more expensive
- Sell Price — bid on the selling exchange
- Spread % — gross price difference in percent
- Networks — available transfer networks and their status
Step 4: Click any row — detailed pair information opens.
In 5 minutes you're already seeing real arbitrage opportunities in real time.
CEX-CEX Spreads Section
The main section — cross-exchange spreads between centralized exchanges.
How to Read the Spread Table
Each row in the table is one arbitrage opportunity. Key things to understand:
Spread % is the gross spread, not net profit. You need to subtract:
- Trading fees on both exchanges (typically 0.10% + 0.10% = 0.20%)
- Withdrawal fee (if transferring the coin)
- Expected slippage
Example: 0.65% spread → after 0.20% fees → net potential ~0.45%.
Filters and Settings
Minimum spread: set a threshold to see only meaningful opportunities. We recommend 0.40–0.50% to start — below that, profit after fees is minimal.
Exchanges: select only exchanges where you have accounts. No point seeing spreads on exchanges you don't use.
Coins: focus on specific coins or exclude those you don't work with.
Volume: filter by pair's daily volume — exclude pairs below $1–5M to avoid illiquid coins with illusory spreads.
Network Status Icons
Next to each row — icons for available transfer networks:
- 🟢 Green — network available, withdrawals and deposits working
- 🟡 Yellow — limited availability or slower operation
- 🔴 Red — network under maintenance, withdrawals/deposits suspended
This is critical information: if the needed network is down — transfer-based arbitrage is impossible right now.
Pair Detail Page
Clicking a row opens detailed information:
- Real-time order books for both exchanges
- Current withdrawal fees for each network
- Spread history over recent hours
- Net profit calculation at different trade sizes
P2P Section
For monitoring P2P offers and finding spreads between fiat and crypto.
How the P2P Scanner Works
The interface shows the best P2P offers from multiple platforms simultaneously: Binance P2P, Bybit P2P, OKX P2P.
For each currency pair you see:
- Best USDT buy rate (lowest = best deal for buying)
- Best USDT sell rate (highest = best deal for selling)
- Cross-platform spread — the gap between the best buy on one platform and the best sell on another
P2P Section Filters
Currency: select the fiat currency you need — USD, EUR, RUB, KZT, and others.
Payment method: filter by payment type — bank cards, bank transfer, e-wallets. Important: different methods produce different rates.
Minimum amount: exclude offers with minimums above your budget.
Verified sellers: show only sellers with confirmed status and high trade counts.
How to Use the P2P Scanner for Arbitrage
- Set the currency you need (e.g., USD or RUB)
- Find the best USDT buy rate (the lowest rate = best purchase price)
- Find the best USDT sell rate (the highest rate = best sale price)
- Check the cross-platform spread — this is your potential earnings
- Account for payment method — the same seller gives different rates for different payment methods
Triangular Section
Scanner for triangular arbitrage routes on a single exchange.
How the Triangular Scanner Works
SpreadScan automatically evaluates hundreds of three-pair combinations on the selected exchange and shows only profitable routes after deducting fees.
What each row shows:
- Route — conversion chain (e.g., USDT → BTC → ETH → USDT)
- Exchange — which exchange the route was found on
- Profit % — net profit after three trading fees
- Volume — minimum volume across the thinnest pair in the route
- Updated — when data was last refreshed (critical — stale data is worthless)
Triangular Scanner Filters
Exchange: choose the exchange you trade on. Start with Binance or Bybit.
Minimum profit: recommend 0.15%+ — below this threshold, risks outweigh potential gains.
Minimum pair volume: exclude routes with thin pairs — they look profitable on paper but produce heavy slippage on execution.
How to Execute a Triangular Route
- Found a profitable route in the scanner
- Check the update timestamp — data no older than 5–10 seconds
- Open three tabs with the needed pairs on the exchange
- Quickly execute three market orders in sequence
- Log the result
Remember: timing is critical for triangular arbitrage. If a route was shown in the scanner 30+ seconds ago — it's likely already gone.
CEX-DEX Section
Monitoring spreads between centralized exchanges and DEX liquidity pools.
What the CEX-DEX Scanner Shows
For each pair, the scanner compares the price on a CEX (Binance, Bybit, OKX) with the price in a liquidity pool on a DEX (Uniswap, Curve, PancakeSwap, and others).
Data for each opportunity:
- Pair and asset
- CEX price and DEX pool price
- Pool blockchain (Ethereum, Arbitrum, Optimism, Polygon, BSC, Solana, Base)
- Gross spread %
- DEX pool fee (0.05% / 0.30% / 1.00%)
- Current network gas cost
- Estimated net profit
How to Filter CEX-DEX Opportunities
Blockchain: start with Arbitrum and Optimism — gas is cheapest there with sufficient liquidity.
Minimum net profit: set 0.20%+ after gas. On Ethereum mainnet this threshold is higher due to expensive gas.
DEX pool: different Uniswap v3 pools have different fees (0.05% for stablecoins, 0.30% for major tokens). The scanner accounts for this automatically.
Copy Trading Section
OKX trader rankings with analytics on key performance metrics.
How to Read the Trader Rankings
Each trader is scored by a composite score — a weighted combination of several metrics:
- ROI — return over the period (35% weight)
- Win Rate — percentage of profitable trades (25%)
- Max Drawdown — maximum historical loss peak-to-trough (20%)
- Sharpe Ratio — return adjusted for risk (20%)
How to use the filters:
- Period: 7D, 30D, 90D — compare traders across different time horizons
- Min ROI: filter out low-performing traders
- Max Drawdown: limit risk — we recommend no higher than 30–40%
- Min trades: traders with fewer than 50 trades have insufficient statistical basis
What to Look for When Choosing a Trader
Consistency over peak returns. A trader with 15% monthly ROI over 6 consecutive months is better than one with 80% ROI one month and -40% the next.
Drawdown. Maximum drawdown shows the worst period in the trader's history. If drawdown is 60%, you could lose more than half your investment in a bad month.
Subscriber count and AUM. Very high AUM (assets under management) can reduce returns — the trader starts moving the market with their own orders.
Account Settings and Alerts
Setting Up Alerts
SpreadScan lets you configure notifications via email or Telegram when:
- A spread on a selected pair exceeds your defined threshold
- A network status changes (opened / closed)
- A profitable triangular route appears
How to configure: Settings → Notifications → add condition.
We recommend setting an alert for spreads above 0.6% on your top 5 pairs — this eliminates the need for continuous manual monitoring.
Free vs Paid Plan

Tips for Getting the Most from SpreadScan
Tip 1: Work with a real threshold. Don't scan everything — set a minimum spread of 0.45–0.50% and only act on opportunities that pass this filter.
Tip 2: Always check network status. Before every trade, confirm the needed network is green on both exchanges. A red or yellow network means the transfer-based trade is impossible or risky.
Tip 3: Cross-check order book depth. A large spread on a thin pair is a trap. Slippage will consume the profit.
Tip 4: Use spread history. Identify which pairs regularly produce spreads above 0.5% — those are your working pairs. Focus on them.
Tip 5: Set up Telegram alerts. The best opportunities don't appear on schedule. A Telegram notification lets you react fast even when you're away from the screen.
Conclusion
SpreadScan handles the most labor-intensive part of arbitrage — continuous monitoring of prices across multiple exchanges. Instead of manually comparing 17 exchanges and calculating fees, you immediately see the real picture and can focus on execution.
SpreadScan provides data for educational and informational purposes. Crypto trading involves risk.
