My Python scalping bot connects to Binance through python-binance and relies on EMA and RSI signals. Right now every trade fails with “Invalid request parameters,” so no orders reach the exchange. I need a quick, clean fix focused only on that blocking issue. Scope • Inspect the current asyncio-based order placement logic. • Identify why Binance returns the invalid-parameter error. • Patch the code so market, limit, or stop orders submit successfully and match the amounts my strategy calculates. • Keep API keys in the .env flow I already use; do not hard-code anything. • Hand back the corrected file(s) with a short note explaining what changed so I can learn from the fix. If you have solid python-binance (or ccxt) experience and know your way around fast EMA/RSI scalping bots, this should be a straightforward debug session.
