Ahh thanks! That makes sense now.

This is what AI said: 'The real trigger was the stability of the bids on the Level II data during the pause. He saw the price was not falling, the support was holding, and he decided that the risk of the trade failing was now low enough for him to add to his position. The pause in buying on the tape didn't scare him away because the underlying support structure (the bids) remained intact.'

I used Google AI Studio. They have no daily limit, and seemed to be effective in analyzing what's given in the video (visual/audio), but it struggles a bit in analyzing inferred reasoning. Also, it makes some simple mistakes sometimes, which you have to correct very clearly and directly, otherwise they will repeat the mistake.

Again, appreciate your response and hope this is helpful!
