Group] Re: Money Management
I’ve been watching the discussion of
position size and the optimal f concept. It is quite difficult to determine a
good optimal f value. The best way is likely by Monte
Carlo simulations. There are a few relatively inexpensive programs
to run Monte Carlo simulations, but I do not
know if they would interface with MetaStock. One program from PariTech might be
of value.

Re: Money Management
<font size=2
face="Courier New">If I just follow the

the support and resistance levels,
1) The account size is $25,000.
2) The largest losing trade is $2,050.
3) The Optimal f is 27%.
Should I just buy long $25,000 x 27% = $6,750 for
6750 share at $1?
and sell short $25,000 x 27% = $6,750 for 6750
share at $1?
Could you please give any suggestion?
Thank you
