needing help with cell references

The attached worksheet contains two tables - 1 and 2.

The first table contains a history of the Ex-Dividend Dates - or Ex-Dates - of a dividend stock. The second table is a daily price history of the stock - listing the Stock Trade Date, Closing Price, Open Price, High Price, Low Price, and Volume in reverse chronological order from top to bottom.

The stock price typically drops by roughly the amount of the dividend on the Ex-Date because the intrinsic value of the company has theoretically decreased by the amount of the dividend paid out. The formula I need in column S produces the number of Stock Market Trading Days it takes for the stock price to recover from the drop in price on the Ex-Date. In column U, I need the number of Days on the Calendar that it takes for the stock price to recover from the drop in price on the Ex-Date. See the Thick Box Borders.

Doing so requires the following.

First, the Ex-Date listed in column D must be matched to the same date in column K. The price that the stock must recover from is the Close Price on the day BEFORE the Ex-Date, so that is the Price in column L on the next row below the Ex-Date.

Next, that price must be compared to the Low Prices in column O to determine the next Low Price that meets or exceeds that price. Once identified, the number of rows must be counted in order to calculate column S, and the difference in the date values in column K must be calculated in order to fill in column U.

To confirm the formula, compare the values in column S to the manual calculation I did on this one stock in column Z, and likewise compare column U to column AB. See the values marked in red on the price history table.

Thank so much for your help!
