Default Re: How to solve example 5.3 step per step?

These are the given numbers:
Hitrate: 52.1%
Number of test days: 500

The correct result is a cumulative profit of 22%.

How do I get 22%?

Thanks a lot and have a nice day!
The hit rate is the percentage of days you got the direction right, while the profit takes into consideration how much money you made (or lost) when you got the direction right (or wrong). You can read the 22% directly off the figure on page 175 as the final value at day 500.
Where everyone thinks alike, no one thinks very much
