Tell the winner's fortune _ tell your fortune

Is the winner of Tongda letter the future?

The master's explanation of this function is copied from the original: the following is his explanation, intact.

Hello:

Find out whether the "profit rate" function is a "future function"?

Let's first understand the calculation principle of this function:

Profit-taking ratio

Usage:

WINNER(CLOSE) indicates the proportion of profitable disks sold at the current closing price, such as returning 0.2 to indicate 20% profitable disks;

Judging from the above comments, this function itself does not generate data, it is just a wet nurse with a baby in her arms, working for others.

Who do you work for?

It depends on what function is added in brackets. If we add it to make a high price, it will work for the highest price. If you add the closing price, it is the closing price.

If the crime of signal drift must be imposed on it, it is indeed a bit wronged.

Because it's not it that changes, but the function in parentheses.

Did you say "future function"? Or should it not be a "future function"?

I believe the conclusion is already in your mind.
