Begginer friendly UK broker.

I have looked into IB but it requires a 10k initial deposit and also seems a bit complicated. I was thinking of maybe just doing a bot to place orders on trading 212but would prefer if there was an actual API I could use to execute orders. I'm just looking to get a simple MACD strategy going which I've already coded up. Though I will build a more complex strategy over the course of the next year to replace it.

Which brokers do you use and why?
