First, you need a software that can execute programmed transactions, so this is not recommended. Search by yourself, these are all charged.
Second, you need a reliable programming script, which is the most difficult thing. Scripts sold online can't guarantee profit at all. If you can make money, the person who writes the script will also make money secretly. How can you be so kind to share it with you? Large companies that use programmatic trading have their own teams dedicated to constantly updating and optimizing scripts. So this is unrealistic for retail investors.
If you are confident to get a good script that can stabilize your income and have a lot of money to bear the risk of fluctuation, then you can do programmed trading.
