Hi Allan - thanks very much! I am not very knowledgeable about these figures, but I wiill be reading up on them soon ( thanks for the link! ). I have not tried to calculate them myself, I will start by using AB's built-in metrics, but I at least wanted to verify what numbers I should punch into the backtest settings in order to get correct Results. My testing these days is limited to just a few indices, so thankfully I don't think I will need to worry about dividends for the moment 8 - ) but I have saved your post for future reference.
Allan, as long as we are discussing these metrics, and since I will be trying to seriously evaluate some of AB's newer metrics for the first time, I wonder if you or any other knowledgeable people might be interested in commenting on what numbers you would find "acceptable" for the following, which do not have any suggested numbers in the help file. TIA for any advice!
