Learning from Others' Mistakes

Funding rate arbitrage is one of the safest strategies in crypto — when done correctly. But we've seen traders lose money by making avoidable mistakes. Here are the 7 most common ones and how to avoid them.

Mistake #1: Over-Leveraging

The problem: Using 10x or 20x leverage to maximize funding income.

Why it fails: High leverage means a small price move against you can trigger liquidation on one leg. Even though you're delta-neutral, liquidation prices differ between exchanges. If one leg gets liquidated, you're suddenly exposed to full directional risk.

The fix:

Use 2-5x leverage maximum for funding arbitrage
Keep at least 30% of your margin as buffer
Set alerts when margin ratio drops below 50%

Rule of thumb: If you can't survive a 20% price move on both legs without liquidation, you're over-leveraged.

Mistake #2: Ignoring Trading Fees

The problem: Calculating APR based on raw funding rates without factoring in entry/exit fees.

Example: You see a 30% APR opportunity. You enter both positions, paying 0.05% taker fee on each exchange (0.2% total round trip for both legs). After 1 month, you rebalance — another 0.2%. That's 2.4% annually in fees alone, reducing your 30% APR to ~27.5%.

The fix:

Use zero-fee exchanges like Paradex, Lighter, or Variational for at least one leg
Check real execution costs with our Execution Cost tool
Factor in fees when evaluating opportunities — a 15% APR with zero fees beats 25% APR with high fees

Mistake #3: Not Checking Liquidity

The problem: Entering a large position on a thin order book and getting massive slippage.

Why it matters: A 0.5% slippage on entry + 0.5% on exit = 1% round-trip cost. On a 20% APR position, that's almost a month of yield gone.

The fix:

Check order book depth before entering
Enter positions in smaller chunks, not all at once
Prefer high-OI pairs (BTC, ETH, SOL) for large positions
Use limit orders when possible

Mistake #4: Forgetting to Monitor Positions

The problem: Setting up positions and forgetting about them for weeks.

What can go wrong:

Funding rates can flip direction — you go from earning to paying
Margin ratios can deteriorate as price moves
Exchange risk increases over time (hacks, insolvency)

The fix:

Check positions at least daily
Use the Dashboard to monitor rate changes
Set a clear exit plan: close if APR drops below X% or if funding flips

Mistake #5: Chasing the Highest APR

The problem: Always picking the pair with the highest APR on the Dashboard without checking stability.

Why it fails: The highest APR right now might be a spike that reverts in hours. You pay fees to enter, then the rate drops to zero.

The fix:

Use the Strategy page to see average APR over time, not just the current rate
Check the History Explorer for rate stability
A consistent 20% APR is better than a spiking 200% that reverts to 5%

Mistake #6: Opening Both Legs at Different Times

The problem: Going long on Exchange A, then switching tabs to go short on Exchange B. In those 30 seconds, the price moves 0.3%.

Why it matters: You're supposed to be delta-neutral, but if you enter at different prices, you start with a P&L imbalance. On a $10,000 position, 0.3% = $30 immediate loss.

The fix:

Have both exchange interfaces ready before executing
Execute the less liquid leg first (harder to fill)
Use similar order types on both sides (both market or both limit)
For large positions, split into batches and match them sequentially

Mistake #7: Ignoring Exchange Risk

The problem: Putting 100% of capital on one exchange or two risky exchanges.

Historical examples: FTX collapse, exchange hacks, smart contract exploits. If one exchange goes down with your funds, delta-neutral strategy doesn't save you.

The fix:

Diversify across exchanges — don't put more than 30% of capital on any single exchange
Prefer battle-tested exchanges (Hyperliquid, Paradex) over brand-new ones
Use on-chain exchanges where you control your funds (true DEXs)
Factor in the risk-adjusted return: 15% APR on a trusted exchange > 40% APR on a sketchy one

Bonus: The Meta-Mistake

The biggest meta-mistake is not using tools to help you. FundingView exists specifically to prevent these mistakes:

Dashboard — See all rates at a glance, don't miss rate flips
Strategy Finder — Find consistent opportunities, not just spikes
History Explorer — Check rate stability before entering
Execution Cost — Know your real costs before trading
Backtest — Test strategies with historical data before risking capital
Exclusive Offers — Reduce your fee costs

The Bottom Line

Funding arbitrage is a great strategy, but only if you respect the fundamentals: manage leverage, account for fees, check liquidity, monitor your positions, and diversify exchange risk.

Avoid these 7 mistakes, and you'll be ahead of 90% of funding arbitrage traders.
