I use IG and haven’t found too much of a problem. A friend of mine swears by Trade 365 with their good fixed spreads. They are Australian but I believe they have offices in London.
Ah I’m surprised you’d say that, IG so far is the best broker I’ve used, and believe me I have tried way too many. Especially like their instructional material, so darn helpful for a new trader learning different strategies, use of stop loss, etc. Fxview for me comes a close second. Primarily because of the low cost, both spreads and commission. And if you ask me floating spreads are actually better than fixed on so many counts. You’ll get extremely lower spreads during the volatile hours. And if you restrict your trading to those 2 hours in the morning, you will be saving yourself a lot, far more than what you can on fixed spreads.
Aaagh! IG down again - no screens, delayed prices, it’s deleted all my drawlings/lines - so cannot trade! So frustrated, definitely need to find a new broker and platform… grrrr!
You might consider Hotforex, Tickmill or IB as an alternative. They are all FCA regulated, provide access via ECN and generally keep competitive trading conditions.
