Introduction to Arbitrage Trading
Arbitrage trading, also known as hedge trading, follows the "market neutral" principle by simultaneously executing two correlated, opposite-direction trades with equivalent volume to offset gains and losses. The most common arbitrage occurs between qualified paired assets - buying undervalued assets while shorting overvalued ones, then closing positions when spreads normalize.
Fundamentally, arbitrage traders:
- Create portfolios using two assets
- Trade the price differential (spread) between them
- Profit from spread fluctuations while neutralizing direct price volatility
Core Arbitrage Methodology
When selecting Asset A and Asset B, we define the spread as:
diff = price_A - price_B
Execution Process:
- When diff is low → Go long on diff (buy A + short B)
- When diff rises → Close positions (sell A + cover B short)
- Reverse logic applies for shorting spreads
Example:
Using OKEx BTC perpetual contracts (A) and BTC quarterly contracts (B):
- Initial spread: -100 USD/BTC (long 1 BTC)
- Closing spread: -50 USD/BTC
- Profit: 50 USD from spread widening
Asset Selection Criteria
Optimal arbitrage pairs require:
- Strong price correlation (e.g., OKEx cross-contracts, contract vs. spot, or cross-exchange pairs)
- Adequate spread volatility to overcome 4-transaction costs (2 opens + 2 closes)
- Convergence within delivery cycles to avoid pre-maturity liquidation
- Low platform fees (critical for thin-margin strategies)
Top recommendation: OKEx BTC perpetual + quarterly contracts.
Grid Trading Fundamentals
The grid trading method operates on mean reversion principles:
- Places staggered buy/sell orders at fixed intervals
- No stop-losses (relies on eventual price reversion)
- Excels in ranging markets
This aligns perfectly with crypto arbitrage since contract spreads must converge (perpetual ↔ delivery contracts → spot).
Medium-Low Frequency Grid Strategy
Setup:
Track diff = BTC perpetual price - BTC quarterly price
Historical pattern: Oscillates between +1% to -3% over 1-month periods
Execution Protocol:
Long Grid Example:
- Price drops to Grid Level 1 → Open Position 1 (long perpetual + short quarterly)
- Drops to Level 2 → Open Position 2
- Drops to Level 3 → Open Position 3
- Price rebounds → Close Position 3 → Position 2 → Position 1 sequentially

Key Features:
- Zero-difference convergence enables non-stop-loss strategy
- Directional grids activate based on spread sign (long when diff<0; short when diff>0)
- Manual execution feasible with larger grid intervals
Risk Management
1. Unilateral Liquidation Risk
Mitigation:
- Maintain low overall leverage
- Rebalance margins when positions approach danger zones
2. Fee & Funding Rate Impact
Solution: Use wider grids to ensure profit > (fees + funding costs)
3. Delivery Timing
Protocol: Close all positions pre-delivery to avoid unconverged spreads
Strategic Advantages
- Market-neutral returns regardless of BTC price direction
- Simple logic without complex technical analysis
- Manual-friendly with medium-low frequency approach
- High success probability from forced convergence

FAQ Section
Q: What's the minimum capital requirement?
A: Depends on contract sizes - OKEx allows small-position testing with $100+ capital.
Q: How often should grids be adjusted?
A: Medium-low frequency suggests 1-3 rebalances weekly based on volatility.
Q: Can this work for altcoins?
A: Yes, but prioritize high-liquidity pairs with tight spreads.
Q: What's the optimal grid size?
A: Backtest suggests 0.5-1.5% intervals for BTC contracts.
