Then you can use the Max(d:d) function to get your biggest drawdown, or large(d,d,5) to get the fifth largest drawdown, etc. We sometimes write this last formula as max(M+ - V4,0) or (M4 - V)+. There are many different ways to calculate drawdown in Excel, but the most common and simplest method is to use the drawdown function. Test the solution provided in the youtube video and see if it really works. Column B should give you every maximum drawdown from a new equity high. Once you can identify the peaks and troughs, getting the maximum drawdown should be straightforward. If this is what you are trying to do, the hardest part is the peak and trough identification. total seconds 0. total seconds 0.3050175 test8 - running drawdown test with 180 period rolling window. drawdown.Populate the entirecolumn R withthe drawdown durations ofthe. total seconds 0.2940168 test7 - running drawdown test with 60 period rolling window. I did not explore in detail if that is an adequate algorithm to find the peak to trough numbers, but he seemed to think it was.Ģ) Once you can compute your drawdowns (peaks to troughs), then it should be a simple MIN() to find the maximum drawdown. get back to Excel In any excel cell type MDD( and select the returns you would like to calculate a maximum drawdown for. test6 - running drawdown test with 30 period rolling window. Another return from my internet search was this video He uses a simple "to date" maximum to compute the peaks. This kind of "signal processing" algorithm can get quite involved, but will be a key part of how you perform the calculation. I will agree with alansidman, your post assumes that we are all financial experts who know exactly what maximum drawdown is and how it should be calculated.Ī quick internet search found this page that talks about maximum drawdown: Can we assume that this is the definition and computation procedure you are wanting to use for what you call maximum drawdown?Īssuming the investopedia article represents the calculation you are trying to do, here's how I would expect to proceed (note that, without using a VBA UDF or similar, I would expect this to require several helper columns).ġ) You need some way to locate your peaks and troughs.
