I would say there are certainly issues still remaining with the platform, but it hasn't been enough to stop me trading with you.
Specifically I have been using your platform over others for trading DOW intraday, mainly because your spread remains tight during after hours which is great if I want to run a position beyond U.S closing, however, the ticket freezes and then greys out quite regularly during the day and it tends to do so at major supports or resistances on lower chart time frames - I guess your volume picks up at those levels, however, this has cost me a fair few points at times where I'm waiting for the ticket to come back to life so I can exit a position, sitting there helpless whilst price is reversing hard from my desired exit.
From a longer term swing trading point of view, I've still not had any issues with those huge random spikes you get on your minor FX charts actually taking out or affecting any of my positions.
I opened an account with City Index just to have someone else who's new to me to compare against your platform, but I've been trying to pay money into that account for over a Week now and they wont accept any of my payment details for some reason, eventually blaming my bank/card provider. If I can't pay money into the account, I dread to think what problems I may have when it comes to making withdrawals!
