Do you mean you can watch the share price of the "Company IG" on LSE and if there are issues with the company itself then withdraw your money! .. h..m yes one way to get out and not become "unsecured creditor"Yeh but with IG you can watch the share price, since they are listed on the LSE. Any issues are likely to be signalled well in advance there. Can't do that with FP.
SO in that sense they might be better than other's but at the end of day NO protection as such as compared to brokers who are are in a jurisdiction which provides some concrete guarantee like in UK or SIPC in USA
Some brokers like IB bundle everything in one SIPC protected account and and they swipe the money in to this SIPC protection so even your cash seating to play CFD/ futures etc ?( IB offers US Share CFD not AUS) is protected as if your were only trading shares!
Any way it is up to you, bigger might be better! but this entire claim of DMA/ STP/ ECN is questionable
OTC products .. be careful counter party is the broker many times if they can't hedge in the underlying market or if there is no direct underlying market ! read the fine print
