Have traded with City for about 2 years.
I like the 1 point dow spread especially as it is up until 9.15 unlike certain other providers also the ftse 1 point spread is great too right up till 9 pm.
In a nutshell in my experience platform works ok about 95% of the time.HOWEVER particularly when market is moving very fast it strugles to cope and opening/closing positions can be a problem.
Its not the best platform for sure and has even cost me money now and then but all things considerded I still like them.
This month for instance I have probably only had a couple of instances where it has not performed.
