API Error [-1111]: Precision is over the maximum defined for this asset.

You do have precision check in binance-service.ts, but sometimes the error still persists:

🔄 Executing trade with stop orders: SOL BUY 33.88
🔄 Executing trade: SOL BUY 33.88 (Leverage: 10x)
✅ Connected to Binance API
API Error [-4046]: No need to change margin type.
ℹ️ SOL is already in CROSSED margin mode
✅ Leverage set to 10x for SOL
API Error [-1111]: Precision is over the maximum defined for this asset.
❌ Order execution failed: Binance API Error: Precision is over the maximum defined for this asset.

Hi @airbagdeer, thanks for reporting this precision error issue.

Good news! We already have PR #4 open that specifically addresses this exact problem. The PR implements dynamic precision fetching from Binance API instead of using hardcoded precision mappings, which should completely resolve the error you're experiencing.

PR #4 Details:

• Fetches and dynamically from Binance API
• Removes all hardcoded precision mappings
• Includes proper error handling and fallback mechanisms
• Adds symbol info caching to improve performance

I'll review and merge this PR shortly, which should permanently fix the precision errors you're seeing. The implementation looks solid and should handle all trading pairs automatically without manual precision maintenance.

Thanks for your patience while we get this fix merged! 🚀

Currently, PR #4 doesn't include unit tests yet, so I won't be merging it for now. If you frequently encounter this issue, you can try pulling the changes from PR #4 to fix it yourself temporarily.

thank you!

I have tried pulling the changes for pr #4 , and I still get the issue

[terryso]

There is another PR #16 , you can have a try

@airbagdeer Could you please post your error log? I just tested it with branch #4 and it works fine.
