AI Cryptocurrency Arbitrage Trading: The Ultimate Implementation Guide

Complete Arbitrage Opportunity Detection Algorithm:

“`python
def detect_arbitrage_opportunities(exchange_data, min_profit_threshold=0.5):
“””
Detect arbitrage opportunities across exchanges

Args:
exchange_data: Dictionary with exchange prices and fees
min_profit_threshold: Minimum profit percentage to consider (after fees)

Returns:
List of viable arbitrage opportunities
“””

# Calculate fees
buy_fee = exchange_data[buy_exchange][‘taker_fee’]

Regulatory Compliance Checklist:

1. Verify legal status of arbitrage trading in your jurisdiction
2. Complete full KYC verification on all exchanges
3. Implement record-keeping system for all transactions
4. Consult with crypto tax specialist for reporting requirements
5. Monitor regulatory news for changes affecting arbitrage
6. Consider forming a legal entity for large-scale operations
7. Implement anti-money laundering procedures if required
