Double-check the side (buy/sell) and position side (long/short) — mistakes are costly
Verify sufficient balance before placing orders
Validate limit prices against current market to avoid obvious errors
Warn about high-leverage orders — clearly state the liquidation risk
For large orders, check order book depth to estimate slippage
Rate limit awareness: Trading APIs are limited to 30 requests per 10 seconds per user
