Hi guys,

I am a software developer and am currently working on the topic of trading bots.

I want to dedicate myself to the topic for fun and am currently developing an HFT bot. I have two approaches for this:
1. a bot that monitors different cryptocurrencies on different trading platforms. It buys and sells a coin immediately if there is a price difference of at least x on one platform.
2. a bot that monitors two different currency pairs on one trading platform and trades based on historical price movements. These currency pairs should move similarly. I am thinking of BTC/USD and BTC/FDUSD, for example. When a price difference occurs, the coin that normally follows the other is bought or sold.

Can anyone tell me if BTC/FDUSD "follows" the BTC/USD market and follows suit. Or if there are alternative coins?
And does anyone have any tips for trading platforms that I can use for 1.?

Thank you for you help
