1）Find the position of the data whose trading time is at 9:00:00 everyday，Daily is a logic vector
2)  Find the corresponding equity price at 9:00:00 everyday. This line of code is better to be written as: DailyEquity=DynamicEquity(Daily)

3)  Convert the equity price to return. tick2ret=tick to return.
