I'm using optionvue from 2005 but with the new version I have several problems. 1)BackTrader doesn't work 2)when I place a new trade in the matrix the program is stopped. 3) When I try to download data with another data feed some expiration months disappear. 4)Until now I've used netvue for end of day data with little cost(around$35 at month). Now I must subscribe a real time data if I want collect data with $145 every month. I don't know what happen at these guys,but they are crazy,also I have sent severals emails at technical support but no answers comes back. Any suggestion?
