I have been trading options off-and-on over the last 17 years. In my first few years I was trading full-time on the ASX (mainly AMP, ANZ, BHP, CBA, NAB, RIO, WBC and XJO) and was only ever on the buy side - I made some good money for a few years, but you would only ever make your annual salary from the one or two big wins in the year.
During those initial years I was introduced to premium selling using the Optioneer system, but the higher returns from being on the buy side were too alluring so I never really persevered with premium selling. Although I had one friend who did and he did quite well from it.
By the end of 2007 my buy-side options trading came to an end as I ended up wiping my account out.
It wasn't until the end of 2015 that I came across the TastyTrade site and have been trying the premium selling strategies of Iron Condors, Iron Flys, Credit Spreads and Calendars to some success. I currently use OX as my broker and I can't wait for the TastyWorks team to allow Australian accounts!
The only downside with trading US markets is the time difference, but as I have a full-time job it wouldn't be any easier trading the Aussie markets anyway.
