Trading bot development

I need to build a bot that buys/sells quickly and a lot, let's say 1000 transactions in a couple of days, and it must have very good performance at least in short periods That's what I need, so I can use it as a foundation for my main idea. The bot will be a crypto bot, trading the best performant coins at the same time as a market maker. It can be developed in the language/platform of your preference but must be fast for the amount of trading required.
