Can we use a simple Excel formula to get the same results as the VBA macro?

    Can we use a simple Excel formula to get the same results as the VBA macro?

    Dear all,

    There is a macro to calculate the maximum drawdown for a stock during a time period:

    Can I ask if we do the same thing using a simple Excel formula, rather than having to use macro?

    It will be very helpful if there is a simple Excel formula for this, rather than having to use VBA. Any great idea?

    You would need to analyze the logic of the function to see what it is doing.

    I'm not a financials guy, so take my analysis for what it is worth. It appears that the function calculates every possible combination of x(j)/x(i)-1 (% change) where j>=i and returns the minimum value from these calculations.

    I don't see a simple, single cell formula that can replicate this calculation. I'm not very good with the complex, single cell array functions that a lot of people like to use. I expect this could be fairly simple if you are willing to use a helper column.

    I haven't rigorously tested the math, but it seems like, the minimum %change relative to each point will be at the minimum data point after that point. So, assuming data is in A2:A20 (comma delimited):

    Then use the =MIN() function on column C.

    Thanks, MrShorty. I am now convinced that there will not be a single formula to handle this. I'll use multiple separate steps to calculate it
