Was hoping to use them for intraday scalping but the platform is below average and spreads too wide for me - ladder is not static so not great for scalping especially at busy times. Clicking on working orders tab only shows them for a short time then switches back to default view of open positions. 'Pull all' button on ladder doesn't pull working orders submitted using order ticket. Coming from TT and CQG the platform is clunky and slow and generally annoying.
Other annoyances include the lack of a portal where you can login and check account balance, trade history etc - you have to wait for EOD statements.
I switched back to real DMA for scalping and started using Prospreads for medium term trades, where their spreads are better than CFD brokers. This hasn't gone well so far either - my OCO orders have been filled very far away from market prices more than once. Each time they have amended the mistake, which is good but it shouldn't be happening. It's very annoying to miss the morning daytrading session because I have to deal with incorrect fills on my Prospreads account. They don't have the most intelligible statements either, so even more annoyance when trying to figure out where their mistakes are.
Conclusion: you're better off using actual DMA for scalping, especially with the platform advantages you get from TT/CQG and I assume Ninja. Longer term, if they could sort out their OCO issues they'd be ok. Good spreads in relation to other spreadbetting although for intraday there is much, much better available, albeit with a much higher min account balance unless you use a US broker in which case you can have intraday DMA goodness for small deposits. Generally annoying platform could be much improved.
I just tried them again today and downgraded my review from 5/10 to 3/10. Terrible, terrible platform. Ridiculously unintuitive and clunky, laggy, slow to update open positions. Really just terrible.
