On the big screen, all day
The Mistake Meter
Behind the stage, a live chart of the mistakes the hall is making. Every time a trader on stage names one — revenge trading, no stop-loss, over-leverage — everyone who has done the same taps “Me too”, and the bar climbs. By the end of the day the hall can see its own trading, in numbers.
Example — the real numbers come from the hall on the day.
