Nice! It's very simple, but has a few interesting qualities, like not using any third-party library to interact with Binance, giving the bot more flexibility to make use of Binance-specific features in a future extension of this work. For example: Binance's margin trading works a little different from other exchanges.

I would use order book data instead of ticker data, though, since you have more control of your risks regarding the exchange's liquidity.

Well done!
