Hello Chris,
Yes, DAS Trader Pro subscription (IB, TD, CMEG or other brokers) comes with a training account. If you want to practice out of market hours, you can add the replay package for additional $15.00 (Level 1 only)
It is worth to move to DAS Trader Pro if you day trade, customized hotkeys/scripts is not available in TOS (some hot keys available in TOS) like DAS
The functionality and speed of DAS is needed for day trade, it is true that many day traders use TOS.
Best of luck.
