Options prices in qcharts are incorrect a lot of the time. They post the latest prices from the five exchanges without checking if that price is the best bid or best ask. So if the cboe put out a $1.00 bid but their is a valid ise bid of $1.05, qcharts will display $1.00. I'm not sure if this is the same in qfeed but it probably is. Try www.atfi.com or www.naq.com.
