Was wondering if eSignal would be willing to add a few technical indicators to their charts to help us options traders out. How about an "historical volatility" indicator for the stock or index where the trader could choose the length of the study, i.e. a 20-day, 50-day, 200-day historical volatility study. Also, an "implied volatility" indicator using a 1-day at-the-money figure. Also, within an option chain, how about adding a column that gives the user the "days to expiration". This is much more useful info than having the "expiration date" column. When using options software, I like to know how many days are left until the option expires. Anyone else care to comment? Thanks.
