My first blog post will ironically point to another blog. If you are an options trader then you really might want to check this blog daily. This is a blog run by Mark Sebastian, a former market maker turned options mentor. Mark’s entries deal specifically with volatility and term structure. If you trade options on any kind of serious level then nothing else need be said. Volatility and in particular implied volatility is critical to options traders. Enjoy! These insights can be interesting as well as valuable learning lessons.
