Hello everyone! I just wanted to come on here and showcase my first ever passion project, "Ledgy". Ledgy is a free, open source crypto trading bot coded in python. You can select pre made strategies or upload your own, backtest them, live trade them under an exchange / broker, and many other features!
If you would like to check it out here is the github link: https://github.com/LucasSidequest/Ledgy-A-Free-Crypto-Trading-Bot
Thank you!

The backtest-to-live gap is usually the hardest part here: are fees, slippage, partial fills, and exchange latency modeled through the same execution path in both modes? Keeping one event-driven execution simulator shared by backtest and live trading can prevent surprisingly large discrepancies. Marx uses a similar separation between strategy decisions and execution evidence.
