I dont know too much about Options Advantage but I couldn't speak more highly of the Steady Options approach. Kim and Yowster take a complete portfolio approach and trade several different trade plans. When you only trade one approach the P&L ride can be pretty bumpy as any approach goes through a period of working and not working as the market shifts around. Taking a portfolio approach we're encouraged to think not just what is the profit potential of this trade but how does this improve the profit potential of my whole portfolio. This leads to exploration of many different types of strategies (straddles, diagonals, calendars, flys and some more innovative ones) that attempt to add the maximum upside whilst reducing the downside risk to the whole portfolio.....ie. a portfolio that can work regardless of whether the market goes up, down or sideways.
The other key thing is that its not a trade alert service. The trades approach is explained with reasoning/explanation of the long term edge and members are encouraged to learn the trade and make it their own. This is evident in the number of 'unofficial trades' members propose and trade on their own. Beyond the expertise of Kim and Yowster there is a healthy community of members from all different backgrounds and experience levels who are a great help to anyone wanting to learn. I, myself, have had fantastic and thoughtful replies to questions that probably seem obvious to more experienced members but were still something that had been stumping me. I really cant overstate the benefit of the community in helping each other learn.
