The best automated trading software will let you practice stock trading using a live real-time data feed during market hours. This is the preferred method, as it gives traders a very realistic view of how their trading strategy is performing and the ability to feel the highs and lows of daily trading without investing real money. If you can simulate trades, you won't need to open an actual brokerage account until you go "live" with real money. Ask if there is a limit on how long you can run in the simulation mode.

You should look for a robotic software with the ability to simulate strategies in real time indefinitely before you run them live.
