Thanks, Nigel. Unfortunately, your explanation doesn't help. The "extra"
trades sometimes occur a year after being stopped out. I am sorry for not
giving some examples. I had better do so now using the output of Backtest:
Without Equity(1):
ABAX Long 11/Aug/1982 16/Dec/1994
ABAX Long 12/Jul/1995 05/Jul/1996
ABAX Long (max loss) 09/Sep/1996 18/Dec/1996
ABAX Long (max loss) 14/Apr/1998 02/Sep/1998
With Equity(1):
ABAX Long 11/Aug/1982 16/Dec/1994
ABAX Long 12/Jul/1995 05/Jul/1996
ABAX Long (max loss) 09/Sep/1996 18/Dec/1996
ABAX Long 23/Dec/1996 21/Nov/1997 *
ABAX Long (max loss) 14/Apr/1998 02/Sep/1998
ABAX Long 20/Jul/1999 27/Mar/2003 **
* (extra trade, a few days after being stopped)
** (extra trade, almost a year after being stopped)
As I said, it's probably not a matter of "extra" trades when I use the
Equity statement. It is more likely "missing" trades when I don't use it.
Cheers
