For the avoidance of doubt, what I stated is fact. I have been trading UK options since 1999. I cannot hold stocks in my account, it's purely options. The ONLY free options data we get is 15 mins delayed.(weirdly they quote prices at the open ).
I have to phone in my orders. There is only IB to trade strategies online for UK options and the cost of their frankly lousy live data is about £10 a month. I place 30-40 trades a year, use limit orders as I trade near month- 6 months hence. And yes my broker's name begins withan 'A'. Saxo bank have an ok platform, basic and functional.
