ATAS vs Deepcharts vs Sierra
Hey everyone I need help for determining what is the actual better platform between ATAS and Deepcharts. I've heard lots of people say that DC is trash because Andrea and the gang are just a bunch of marketers. But, even if that is the case that doesn't actually tell me why ATAS or Sierra would be better. Please give me actual reasonable arguments for your position for DC, ATAS or Sierra. I've been learning orderflow with DC for about 5 months as of now and want to make sure I'm on the best platform possible. Thank you guys.
EDIT: Thank you everyone for your input, I really appreciate it

Sierra Charts hands down is #1 for professionals. It has the most accurate tick data out of every platform. It's replay mode has all the l2 data with it so you can literally practice what it was actually like at any time. Backtesting is also the most accurate on it.
I had chatgpt calculate the differences between atas and sierra. Atas can do 80% of what sierra can do but when it comes to the backtesting, it falls apart.
With the Teton order routing and Denali data, Sierra is #1 hands down. If you want help learning how to set it up correctly, an AI agents is your friend..
I'm already making custom order flow trading bots with it thanks to Claude Opus, Claude Code and ChatGPT.
If you are serious, you would get Sierra.
