Trading Logic Issues Found

🔴 Critical Issues

1. Division by Zero Risk in Buy Strategy (postOrder.ts:77)

const ratio = my_balance / (user_balance + trade.usdcSize);

Problem: If user_balance + trade.usdcSize is 0, this causes Infinity or NaN Impact: Could try to buy infinite amount or crash Fix: Add validation before division

2. No Balance Validation Before Buying

Problem: No check if my_balance is sufficient for calculated remaining amount Impact: Could attempt to buy more than available balance, causing order failures Fix: Validate balance before executing buy orders

3. No Array Validation for API Responses

Problem: fetchData could return non-array, causing .find() to fail Impact: Could crash when processing positions Fix: Validate API responses are arrays before processing

⚠️ Important Issues

4. No Delay Between Retry Attempts

Problem: Retries happen immediately without delay Impact: Could spam API, get rate-limited, or waste resources Fix: Add delay between retry attempts

5. Price Slippage Check Only in Buy Strategy

Problem: Sell strategy doesn't validate price difference Impact: Could sell at much worse price than target user got Fix: Add price validation to sell strategy

6. No Validation of Order Amounts

Problem: Could create orders with 0, negative, or invalid amounts Impact: Wasted API calls, potential errors Fix: Validate order amounts before creating orders

7. Potential Race Condition

Problem: readTempTrade could be called while doTrading is processing Impact: Same trades could be processed multiple times Fix: Add locking mechanism or process flag

8. No Error Handling for Balance Checks

Problem: If RPC call fails in getMyBalance, error propagates Impact: Could crash the bot Fix: Add try-catch with fallback values

💡 Minor Issues

9. No Validation of Trade Data Completeness

Problem: Trade object might be missing required fields Impact: Could cause runtime errors Fix: Validate trade object before processing

10. Inconsistent Error Handling

Problem: Some errors mark trade as processed, others don't Impact: Could leave trades in limbo Fix: Standardize error handling
