Quote from rselitetrader:
Thank you all for your informative replies. Some options spreads have limited profit potential and unlimited risk. If brokers allow people to place these spreads (e.g., short staddles and ratio verticals), then essentially the brokers give these clients "unlimited credits" and hope they would be "responsible for their own purchases" -- to quote from FullyArticulate. As I recall, some years back, COMEX was in trouble because some traders were short a large number of options. I assume these were experienced traders. I also recall the story of Vanderhoffer who blew up, and he was a veteran trader too.
Considering expectancy and fat tail, new traders blow up often but probably in small scale; some veteran traders occasionally blow up, but could be enough to bring down the house. Which is better for the broker?
Anyway, I don't want to be handicapped in trading and want to have at my disposal the full spectrum of option strategies. I can ask IB to give me a test, closed book and proctored, if required.
Now the question is, did you have to go through a series of challenging obstacle course to prove you are worthy to kiss the graceful hand of a king's daughter before your broker allows you to trade short straddles, ratio verticals, etc.? Or is this a moot point as long as you have sufficient capital?
