TL;DR:
- An arbitrage trading checklist verifies critical pre-trade criteria such as contract match, net edge, liquidity, and operational readiness to ensure risk-free, profitable trades. Automation filters help eliminate false positives by setting spread, volume, and data freshness thresholds for effective scanning, while risk management controls prevent execution failures from becoming major losses. By adhering to comprehensive compliance requirements like MiCA in 2026, traders can operate legally and avoid operational disruptions amid evolving regulations.
An arbitrage trading checklist is a systematic set of binary criteria that traders must verify before executing any trade to confirm the opportunity is genuinely risk-free and profitable. Without this verification framework, what looks like a clean spread can quietly become a directional bet. This guide covers every layer of that framework: pre-trade validation, automation filters, risk controls, regulatory compliance, and scanner selection. Whether you trade crypto, futures, or prediction markets, these checklist items apply directly to your workflow and your capital.
1. The core arbitrage trading checklist: seven items every trade must pass
A rigorous pre-trade checklist confirms seven key items before any capital moves: contract equivalence, combined costs below payout, positive net edge, sufficient liquidity, rapid execution capability, awareness of operational constraints, and a contingency plan for partial fills. Each item is binary. Fail one, skip the trade entirely.
1. Contract equivalence. Both legs of the trade must settle identically. A mismatch in expiry dates, settlement currency, or contract size creates hidden basis risk that erodes your edge before you even execute.
2. Combined costs below payout. Add every cost: exchange fees, gas fees, slippage estimates, and funding costs. If the sum exceeds the gross spread, the trade has no edge. Many traders calculate gross spread correctly but forget gas on Ethereum-based DEX routes, which can consume 40 to 80 basis points alone.
3. Positive net edge. After all costs, the remaining profit must justify the capital deployed and the execution risk. A 0.05% net edge on a $10,000 position is $5. That is not worth the operational exposure.
4. Sufficient liquidity. The market must absorb your full position size without moving the price against you. Top-of-book prices are often misleading; you need full order book depth to confirm true liquidity and avoid edge erosion.
5. Rapid execution capability. Both legs must execute within a time window that prevents price divergence. If your infrastructure adds latency beyond what the spread can tolerate, the trade is not viable.
6. Operational constraints awareness. Check API rate limits, withdrawal restrictions, and exchange-specific rules before committing. A locked withdrawal on one leg turns a hedge into an open position.
7. Partial fill contingency. Define in advance what happens if only one leg fills. This is not optional planning. It is the difference between a managed outcome and an unintended directional trade.
Pro Tip: Write your checklist as a literal pre-trade form, not a mental checklist. Traders who document each item before execution catch constraint failures that memory misses under time pressure.
2. How to configure automation filters for your arbitrage scanner criteria checklist
Automation filters are the first line of defense against false positives. A well-configured arbitrage scanner criteria checklist prevents your system from wasting capital on spreads that look attractive but cannot be profitably executed.
- Minimum spread threshold. Set a floor of at least 0.20% before a spread triggers evaluation. Anything below this level is typically consumed by fees and slippage before execution completes.
- Liquidity floors. Exclude any market with insufficient depth to absorb your trade size. Automated strategies prioritize pairs with more than $500k in 24-hour volume and filter out dust pools entirely.
- Quote freshness limits. Reject any spread signal derived from data older than 8 seconds. Stale quotes are one of the most common sources of phantom arbitrage signals, particularly on low-volume altcoin pairs.
- Volume criteria. A minimum $500k daily volume threshold filters out markets where a single trade would constitute a meaningful percentage of daily activity, creating immediate market impact.
- Persistent spread filters. If a spread has been visible for more than 60 seconds without being taken, treat it as a red flag. Persistent spreads often indicate a withdrawal restriction, a delisted asset, or a data feed error.
Pro Tip: Test your filters on historical data before deploying live. A filter set that looks conservative in backtesting often proves aggressive in live markets where data quality degrades unpredictably.
3. Risk management elements for your arbitrage risk management checklist
Risk management in arbitrage is not about avoiding losses on individual trades. It is about preventing a single execution failure from becoming a portfolio-level event. Your arbitrage risk management checklist must address four structural risks.
1. Pre-fund both legs. Pre-funding and synchronous execution reduce leg risk by eliminating the gap between leg one and leg two. Sequential execution exposes you to market moves between legs, converting a hedged position into a directional bet. Atomic execution, where both legs settle simultaneously, is the gold standard.
2. Define exit rules before entry. Exit rules must be defined before entry to avoid costly mistakes during volatile regimes. Write specific triggers: funding failure, basis drift beyond X basis points, or counterparty withdrawal freeze. If the trigger fires, you exit. No deliberation.
3. Monitor full order book depth. Snapshot the full depth of the order book, not just the top bid and ask. Ignoring full depth risks wiping out small arbitrage margins instantly when your order walks the book.
4. Define operational limits. Set a maximum position size per trade, a maximum daily loss threshold, and a slippage tolerance cap. These limits remove the temptation to override your own system when a trade looks “almost good enough.”
Arbitrage scanners are triage tools that inform traders but require internal governance and risk caps to manage market volatility effects. Automated signals must be vetted to avoid trading on false positives or system outages.
Pair these controls with real-time market monitoring alerts so that any breach of your defined thresholds triggers an immediate notification rather than a delayed manual review.
4. Regulatory compliance requirements for arbitrage desks in 2026
Compliance is not a back-office concern. For arbitrage desks operating in crypto markets, it is an operational prerequisite. EU crypto-asset service providers must comply with MiCA from July 2026, implementing a full stack of operational requirements that directly affect how arbitrage trades are structured and recorded.
Your compliance layer must address these items:
- MiCA authorization. Any desk operating in EU markets must hold or operate under a MiCA-authorized entity. Trading without authorization after July 2026 creates legal exposure that no spread justifies.
- Travel Rule data exchange. Transfers above threshold amounts require sender and recipient data to accompany the transaction. Build this into your execution workflow, not as an afterthought.
- Segregated custody. Client and proprietary funds must be held separately. This affects how you pre-fund legs and how you account for capital allocation across strategies.
- Best execution policies. You must document that each trade was evaluated on price, speed, and likelihood of fill. This is not just good practice. Under MiCA, it is a reportable obligation.
- Market abuse surveillance. Automated surveillance must flag wash trading patterns, layering, and spoofing. Even unintentional patterns triggered by your scanner can attract regulatory scrutiny.
- Quarterly reporting. Transaction records, position data, and execution quality metrics must be compiled and reported quarterly.
The crypto compliance checklist for high-risk banking provides additional detail on how these requirements interact with banking relationships for crypto-native desks. Ignoring compliance does not just create legal risk. It creates operational disruption at the worst possible time.
5. Comparing arbitrage scanner tools: features and trade-offs
The right scanner does more than surface spreads. It simulates execution, filters noise, and tells you when to skip a trade. Here is how leading tools compare on the criteria that matter most for your trading checklist for arbitrage.
| Feature | Cascade | ArbScan | Custom-built scanner |
|---|---|---|---|
| Spread threshold filter | 0.20% minimum | Configurable | Fully configurable |
| Quote freshness limit | Rejects quotes older than 8 seconds | Varies by setup | Depends on data feed |
| Price impact simulation | Yes, with slippage modeling | Limited | Depends on build |
| Net profit calculation | After fees, gas, and slippage | Fee-adjusted | Custom logic |
| Confidence threshold | Yes, skip/execute decision | No | Optional |
| Governance layer | Manual override required | Manual | Fully custom |
Cascade simulates price impact and slippage and applies confidence thresholds to decide whether to execute or skip a path. It rejects arbitrage routes with stale quotes or insufficient net profit after all costs. This makes it one of the more disciplined tools available for automated execution.
ArbScan offers configurable spread filters but lacks native price impact simulation, which means traders must calculate slippage manually or accept the risk of edge erosion on larger positions. Custom-built scanners offer the most flexibility but require significant engineering investment and ongoing maintenance.
Pro Tip: No scanner replaces governance. Automated signals must be vetted to avoid trading on false positives or system outages. Build a human review step into any fully automated execution pipeline.
Key takeaways
A complete arbitrage trading checklist integrates pre-trade validation, automation filters, risk controls, and regulatory compliance into a single framework that every trade must pass before capital is deployed.
| Point | Details |
|---|---|
| Seven-item pre-trade validation | Every trade must pass all seven criteria; failure on any single item means skipping the trade. |
| Automation filter configuration | Set minimum spread thresholds, liquidity floors, and quote freshness limits to eliminate false positives. |
| Risk management structure | Pre-fund both legs, define exit rules before entry, and set hard operational limits on position size. |
| MiCA compliance by July 2026 | EU arbitrage desks must implement Travel Rule, segregated custody, and best execution documentation. |
| Scanner selection trade-offs | Tools like Cascade offer price impact simulation; all scanners require a human governance layer. |
Why checklist discipline matters more than chasing spreads
At Handy, we have watched traders obsess over finding the next 0.5% spread while ignoring the checklist items that would have told them the trade was not executable. The spread is the headline. The checklist is the story.
The most common mistake we see is treating the checklist as a formality rather than a filter. Traders who skip the liquidity depth check because “the spread looks obvious” are the same traders who discover their order walked the book and consumed the entire edge plus more. The checklist exists precisely because obvious-looking opportunities are often the most dangerous.
We also believe that scanners like Cascade and ArbScan are genuinely useful, but they are not decision-makers. They are information tools. The governance layer, the exit rules, the position limits, those live with you. No scanner will tell you that your exchange has quietly restricted withdrawals on the asset you just pre-funded. Your operational checklist will.
Compliance is the item most traders defer until it becomes urgent. MiCA authorization, Travel Rule workflows, and best execution documentation are not bureaucratic overhead. They are the infrastructure that keeps your desk operational. A compliance failure does not just create a fine. It can freeze your accounts at the moment a major spread opportunity opens.
The traders who perform consistently are not the ones who find the best spreads. They are the ones who execute the same disciplined process on every trade, every time.
