It is obvious that the sponsors stand by their commentary in their own trading. I attach a lot of credibility to people who put their own money where their advice is. This helps one stay away from overtrading, and maximize bang for the trading buck. Likewise, the website sometimes misses out taking trades that, in retrospect, turn out to be powerful moves that could have been very profitable.

The world of options conjures up images of greek symbols and names such as theta, vega, delta and complicated matrix calculations. This website, to the best of my memory, has never made mention of anything except volatility - which anyway is the core of today's markets. The commentators take pains to reply to any clarification emails sent to them, usually within a few hours of posting the query. The emphasis is on Analysis, and not black-box indicators. Specific proprietary indicators that have consistently worked over time are those that highlight changes in market sentiment at the extremes, normally with one day in advance.
