You choose a platform at checkout.
Choosing between them
Quantower is the multi-asset choice, with connections to a wide range of brokers and feeds, a large indicator set, and a workspace you arrange yourself.
DeepCharts runs in the browser with nothing to install, and is built around order flow: footprint, volume profile, and DOM.
ATAS is the deepest order flow toolkit of the three, widely used by volume traders, and the heaviest to run.
Switching later
You cannot change it after checkout. The platform you pick is tied to the data feed your account is issued on, so choose the one you want to trade on before you pay.
What is included
Live market data for the exchanges you can trade: CME, CBOT, COMEX, and NYMEX. You are not billed separately for a data subscription. What you can trade
Third party tools
Custom indicators, automated systems, and external analysis tools are your own responsibility. They are allowed, and problems caused by them are not grounds for a refund.
