At first I thought you meant volume. Would have really appreciated an analysis of changes in vol over the last 2 weeks. But I suspect that vol = volatility.
If you were presented with the graphs above how would you use the information contained to influence your trading?
If it means there is more volatility now then before I know that. However, if you can tell me where the volatility is coming from that would be appreciated.
Also how are you measuring implied volatility. Some use a form of bid ask spread. Some use a value that makes their option pricing model work all other things remaining the same - ceteris paribus.
