Quote from Thunderdog:
You can get the RTH only with a suffix of "=2" for the CME mini indexes. So, to get the RTH continuous ES contract (which switches to the correct front month on the appropriate day every quarter), you would use: ES #F=2.
As I understand it, rates vary according to what markets you wish to follow. I get the basic package which only entitles me to the mini equity indexes. I subscribe annually and get a fairly good rate, about equivalent to what QCharts charged when I was with them. (My annual subscription renewal in July will be $1,020, excluding exchange fees, minus a small discount. I think it would be about 25% more expensive on a month-to-month basis.) However, admittedly, I had access to just about everything with QCharts' basic package if I recall correctly. So, there is a trade-off, dollar-for-dollar. However, data integrity is non-negotiable.
