after comparing the performance from 1JUL to 6JUL in other models in other round, i start to realize that all the model facing certain down turn in that period. And it lead to my following understanding:
- daily score is an accumulated score from round stating date to end. It is same like floating gain or lose situation.
- the score in the day 1 will be very close to zero as the calculation just started.
So we need to be patient to wait the market gradually aligned with prediction and score result move up daily.
