So it is not significant does trader do long term or short term - that they will shed. In any data over time there is 50%-50% without disperse so it is not significant do trader do buy or sell. Probability changes based on stop loss and profit target.

However, what makes me think how to profit in short term daily on probability events, there is only one mathematical edge to exploit - standard deviation of multiple independent events.

When first time tested this edge it was too much profitable typical 400-600 pips per day so I canceled it. It was to fast so I discarged it believing it is impossible.

3075 pips in seven days. That is impossible but it is based on standard deviation of multiple events.
