After you purchase the software package what other monthly expenses do you incur? Do you have to purchase the monthly data package at 149/mo or do they offer delayed/end of the day data?
If you want access to the back trader, that's $500/yr. OpScans are also $500/yr I believe. You'll also need a suscription to keep the software updated when they release bug fixes. Otherwise it's a few hundred bucks for each 0.0x maintenance release. I personally would think about their data service as it is proprietary and only useful with OptionVue 6. They do support eSignal which is more expensive, but you can use eSignal data in many other programs plus the eSignal charting is far superior to OptionVue's built in charting.
