I wanted to get opinions on three websites that provide information, charts, data on seasonal patterns for futures and futures spreads. I've been signed up with one for a few years now, but thinking about switching. Here are the three sites: 1) www.scarrtrading.com I've enjoyed using this site over the years. It provides mostly visual inspection of seasonal and other futures/spreads patterns. Somewhat limited in really digging down into patterns (for example, not an easy way to see what are the best patterns for a month or pick outt one particular year that is highly correlated with a current pattern). Subscription is $250 per year. 2) www.timeandtiming.com Massive databases and loads of features to not only look at seasonal patterns, but also other pattern data mining (selecting highly correlated years, specific dates, etc.). Subscription is $365 per year. 3) www.seasonalgo.com Really slick interfaces, loads of features, allows for really drilling down, backtesting, etc. But, it seems to be very new and I can't find any information on who's behind this, reliability or experiences, etc. Subscription is $399 per year. What are your opinions on the pros and cons of each website/software? Any other suggestions? Oh, and to be clear, I don't have any affiliations with any of these sites/software vendors except being a subscriber of one. Thanks! E
