UK / FCA regulated brokers



I am looking for a safe broker regulated by FCA as I am based in UK ( or any other non-FCA safe options, if any).
I am fairly new to the forex world and I have being practicing on demo for some time now. I am aware of my naivety and delusion in this world so any suggestion that may help feel my knowledge gap are more than welcome.
I have being considering (so far) HF Markets, Pepperstone and FXopen however FXopen doesn't allow edging so is not good for my strategy.

My strategy is scalping, and I have some raw requirements based on my current knowledge.

MT4 platform
Account size: 50k to 100k GBP
Account type: STP/ECN with commission
Scalping allowed
EA allowed
Edging allowed
No daily operations number limit
high execution rate %

Feel free to ask for any extra required info and thanks for taking the time to read this post.
