The training is supervised, I manually take snapshots of price structures and than look at what transpired post snapshot focal window. Than I manually label the structures based on what transpired.
So if you take a snapshot on the open, and it indicated a signal, place entry with that bias, than use risk management based on what would signal a failure of that structure.
There is a larger timeframe focal window and a shorter timeframe focal window. The bias may differ, so it depends which timeframe your looking at or trading.
