MAE/MFE (was:Re: System Exits)

[Lincoln Fiske <lincolnf@xxxxxxxxxxxxx>]

I believe this code isn't truly MAE/MFE, since the equity calculation it
uses (OpenEquity function) is based on the closes of bars, rather than
extremes. At least that's what it does when I run it. Does anyone have a
simple way to do it so it calculates the actual maximum? I know it can be
done using print statements in your system code, but is there a simpler
way? Too bad Omega dropped this from System Writer.

Thanks.
