"I wouldn't even consider trading the front two months without Derivix.  It is super easy to navigate expirations and price multi-leg calendar spreads, and implied volatilities remain solid right down through the day of expiration."

Dan Hutchison

"Derivix is the best options pricing system I have ever seen or worked with.  It should be the front end solution of choice for anyone volatility trading in the new electronic market."

“Derivix is the only widely available option pricer I’ve seen that offers a realistic and accurate treatment of time decay, all in lightning-fast real-time. This takes all the analytical guesswork out of pricing near expiration and holidays.”

Tom MacFarland, Ph.D

“Derivix is a great pricing system. The pricing engine, with real time decay, is a necessity in the final weeks of option trading. The system layout has been designed for a terrific trading experience.”

“I’ve used a lot of option pricing systems and Derivix is the best I have used to date. Its layout, flexibility in navigating expirations, and ability to price with real-time decay make it a necessity for anyone who wants accuracy and efficiency in trading options.”
