📝 Assumptions

• All orders are placed on Binance Futures Testnet (USDT-M) — not the live exchange
• Base URL: https://testnet.binancefuture.com
• Credentials are loaded from a .env file in the project root
• Stop-Limit orders use Binance's STOP type with both price and stopPrice parameters
• timeInForce defaults to GTC (Good Till Cancelled) for Limit and Stop-Limit orders
• Log files rotate at 5 MB, keeping the last 3 backups

⚠️ Important

This bot connects to the Testnet only — no real funds are involved. Never use testnet API keys on the real Binance exchange or vice versa.
