Not 'intend', we do.
We monitor the trader with a camera (for facial expressions), thermal cameras (for thermal face-mapping), an eye-scanning camera (to measure pupil size and angle of view), and a pulse rate detector. We then take all of the deals he made per day, determine the points of maximum profit at the given positions (+ -60s, the maximum), and refer to these points as reference points. These reference points are used to train a neural network to search for physiological signal patterns of emotions.
+ we already have a patent application for this technology
Wow! Sound interesting but I think you still have a long way to go!
