Has anybody done this ? Is this realistic ? can it be done ? How much money do you need ? Where can you find clearinghouses ? What can you "realisticly" expect to make ? What are the costs ? What do you need for autoquoting software ? Can you do it alone or do you need to be with a group of people ? Like you see lots of questions, I have traded in the nineties for an options market making firm in Belgium so I know my greeks and have done some option arbitrage through IB in DIA options trading something like 200 options a day making 500-1000 USD out of that mainly by beying on the bid or the ask and hedging my delta-positions, (this all changed abdruptly when IB started asking cancellation costs because i canceled something like 800 times each day) so I have some experience. I am American but would prefer to stay in Belgium and have normal working hours. If anybody would have some advice or remarks feel free to give them to me. Not sure if I can meet the requirements but sure anxcious to know.
