How to get my Trading Signals in the right way?

Hello,

I’m currently using the backtest with the “future bar” enabled and selecting tomorrow’s date to identify signals, then checking the trade list for portfolio changes.
My question is: is the backtest already the best and most reliable way to generate actionable signals for the next trading day, or would using a Scan or Exploration be the better approach?

If Scan/Exploration is preferred, how would you typically set this up to get clear entry/exit signals for the next day and monitor portfolio changes?.
I’m especially interested in a workflow that is robust, reproducible, and suitable for manual execution with a broker.

Thanks a lot!
