Dear members

I am struggling to do the following in Excel.
I am testing stock trading strategy.

I have generated variable Trade_1. It takes value 1 for buy signal and -1 for sell.

My next step is to generate Trade_2. It is almost the same as Trade_1. The only difference is that I need to replace any signal with =. for the following 10 days.
In other words after a first buy/sell signal one should wait for the next 10 days and ignore any signals within this period.

The column I is my objective. The signals in red cells I deleted manually to show my end goal.

I have to do it over 100 stocks so the prosess should be automated to reduce human error.

Any tought how to do it?

Thank you.

Square and cube roots
The =SQRT(25) is a square root. For a cube root, use =125^(1/3). For a fourth root, use =625^(1/4).
Welcome to the forum.

In column I enter =G62 (or against the 1st occurrence)
In the next cell in column I enter
=IF(AND(ISNUMBER(H63),COUNTBLANK(H$63:H63)-(COUNT(I$62:I62)*10)>=10),H63,"")
