Great conversations.. I want to add in my two cents...
RISKarb: As you alluded to, the reason the risk haircut has convinced me to go prop is that I can hedge more dynamically in a prop account than in the retail account and actually be credited for such a hedge. That is the main reason for leaving retail. Rollouts and partial hedges is as far as I can go in retail. IN prop I can add mre dynamic hedges and reduce my margin requirements and thus allow me to add more levels of profitability. The pooled money risk is a concern that is always in my head and the person I am talking with has been very helpful and forthcoming in answering my questions on this very issue. And I certainly am gonna take your advice and sweep often
Donna/Maverick: Donna, you have to realize that wiht a $100,000 account you cannot make a serious living trading options. Even a stellar 40% return will net you $40,000 a year. If that is enough for you to live comfortably than it works. But in all honesty you need a large account to make a salary of your returns because you will be tkaing out profits regularly. If you have a large account, then retial or prop you can make a living. But the reason why the pros make more on average is that they get much more generous margin terms than in retail. This allows them to leverage their money more while ironically taking on LESS risk. So the comments were not directed at the average retail who usually has $100k or less. It was directed at those trading with larger accounts. Both can make a living, but I think the one trading with prop haircuts have an advantage and can do much better assuming all other things euqal.
For example if I sell 200 1190/1200 spreads my margin requirement is $200,000 at retail level. For risk-based haircut, it could be much less depending on the index value. If I add any partial hedge I reduce my margin requirement in prop, whereas retail it is still $200,000. Assume I roll into a prego Fly for a net credit, I can then sell deeper OTM credit spreads for more premium and income. In retail, I would still be on the hook for $200,000 in margin and would have no such freedom (unless you pleaded with compliance department). IN prop, my $200,000 margin would be gone due to the hedge added and I can do another $200,000 in positions, "leveraging" my account for even more profits under the right circumstances.
So not to put words in Maverick's mouth, but if you have a large account, it seems the risk-based haricut will allow you to trade with a greater advantage and "leverage" your account for better returns. I put leverage in " " because it is not true leverage like a stock prop shop, but putting your same money to work in multiple postions or more positions because of how your risk is hedges v. retail which will treat each position individually.
I hope that is clear. Anyone can make a living trading options in retail, but I am seeing that getting more advantageous risk margin requirements allows you to trade your capital better. Last example is that a good option prop will allow cross margningin. SO that means an SPX credit spread will be hedges using SPX, XSP, SPY, ES futures, SP futures, ES/SP options on futures or other correlated securities. No retail accounts I know of will give you credit for adding SP options to hedge an SPX credit spread position. They will be treated as separate positons and your margin for the spread will always be there. In option prop they will reduce your margin requirements, thus keeping you in the position with less risk and freeing up capital to trade in other positions. So I get to do more positions with my $$ if I hedge then one can do in a retail account. Your $100,000 acount is $100,000 while in a prop you might be able to trade it up to $200,000 if you properly hedge. Compare each account earning 3%$ for the month ($3,000 v. $6,000).
I do not want anyone to think I am dissing retail at all. I was recently educated on the advantages of moving my account to a prop shop (along with learning the potential cons) and sharing this experience with you. Maverick never said you could not make money in a retail account, he was referring to the ease of making a liviing off of trading a large account with risk-based haricut margin in a prop as compared to doing it with retail. Margin can bite you in the ass as well so of course it still needs to be managed well no matter where you trade.
So this discussion is great for learning about other means of trading and the pros and cons, not to categorically denounce either form.
