After thinking about it for a while I came to the conclusion that what I really wanted to measure was how much patience I required to trade an account (portfolio, system). My patience is based on calendar time. It's easier to calculate and is a more familiar time measurement for me - being human. Psychology is fuzzy science anyway. What's a few days amongst friends! lol But for market indicators, your table/formula will be very useful! So after thinking a bit more about the data made available via the export, and watching Sports Center, I came up with another (perhaps) interesting stat. The equity curve's batting average - the number of new equity highs / number of trading days. For my ARM4 Margin export it was 0.1951 (or 19.51% if one prefers %). So about 1 in 5 trading days is going to give me the thrill of success... I used trading days because it was easy. The export give me one record (row) of data for each trading day. For a BA, times at bat is the accepted denominator. Close enough for government work... Perhaps another component of a tradability index. Keith Oh give me a home, where the MBH is one, and the annualized LRS is 30%. For seldom will be heard, a discouraging word. And the sky won't be cloudy all day! :-) | |
