Finally had enough with those monkeys and stopped using them last year. It was a shame. Sierra Charts used to be really good back in the days. I stopped for a few months, got back to using them last year and everything changed. The software that used to be rock solid and reliable became total crap. All my programs that used to work flawlessly don't work at all anymore and I didn't change not one line of code. The support people were all noobs who know nothing about the software but still think they are God. You ask them something and majority of the time they give you a link and tell you to read their documentation not knowing you've already read the documentation 5 times or it's not in their documentation. And then when they finally give you an answer, you tell them it's not working and they mark your post as "User Discussion" and shut you out. Totally useless. Don't have time to waste with them. Good riddance!
If you just want to trade, just use your broker software. If you don't like your broker software, change broker. Data fees though is from the exchanges, nothing to do with Sierra Charts. Some brokers choose to absorb them some choose to pass it onto traders. Some brokers choose to absorb some only for high-volume traders.
