How do you compute the MAR ratio?

I know it is basically: annualized return / maximum drawdown

However, the MAR group uses month end drawdowns based on total equity including open positions. Is this what Trading Recipes uses?

Do you base this on the account balance of closed out trades or total equity? Only on the month end drawdowns or does it include drawdowns that are based on prices occuring during the month?

It calculates in all the time, not just month end and uses total equity.

Yes - TR calculates MAR as CAGR / MaxDD, and as yp said, it uses the closed daily MaxDD of total equity.

I read somewhere recently that hedge fund rating agencies typically use end-of-month data points to calculate MaxDD, whereas CTAs are subject to MaxDD scrutiny on a daily time-frame. Can anyone confirm this?

Howard I can cofirm that what you are saying is true.
There are some reporting services that allow fund managers to input their #'s on a daily or weekly basis. This has been the trend with the advent of internet, real time services.
I believe Quadriga fund reports on a daily basis now.
Most funds still follow the monthly rule.

CAGR / MDD%

I have posted a spreadsheet here viewtopic.php?p=6468#6468 that has the calc in it as well as a few others. Hope it helps!
