What do you think is the right way of doing MC? If you test a system on a
portfolio of stocks/futures and apply certain money management rules. How
would you do the MC then? We are planning to incorporate MC in our software,
so maybe some of you have any thoughts? We all know that results change
dramatically when using MM and have different starting dates. One way we
could think of is running portfolio-tests with random starting dates...but
is that enough...should we take the results and create random equity curves
afterwards... but then what do we get? So if you have any thoughts about it
and dont want to discuss it here you can email me in privat, thanks.

++You seem confused about the concept. The MC is done during system
++development before you ever start trading the system. The practical
++benefit comes from deciding how big to trade. Can you handle a 50%
++chance of going broke (in return for a 50% chance of getting rich
++quick?) Or do you prefer a slow and steady approach with a very small
++probability of blowing out the account? The MC can tell you how much
++leverage to use to accomplish each of those goals.
++
++It's not for everybody and it's hard to do it right. If you don't
++understand it, forget about it. All it will do is confuse you.
