Grid bot for pionex bitmart, gateio

Hello,

Primary goal: convert the existing MQL5 strategy logic to Python as soon as possible and make it work for API trading (order management, exchange connection, basic bot structure). I want to keep the core logic unchanged.

I haven’t chosen the exchange yet (must be usable in the EU). Binance, OKX, Kraken, and Bybit are not options. Bitmart, pionex, gateio are options.

Secondary goal (code reduction): the current MQL5 code is ~5,000 lines, but only ~1,000 lines or less are core/usable. I want to:

• remove unnecessary parts,
• keep only the basic parameters and core logic (no indicators/extra filters),
• remove the corresponding source code (not just hide inputs).

I also need a backtesting setup: please propose a crypto backtesting tool/environment, explain where/how to run the backtest, and deliver Python code that works in that backtesting environment and on at least one crypto exchange via API. So probably 2 codes would be needed slightly modified.
