I run v
9.0 professional with e-signal for data..
I have been getting massive
data spikes on running the system
tester. e.g. a low of $1.57 on MCD
against the typical price of
around $29. This is despite clearing the
cache prior to running the
test.
The period I was testing with the
system tester was 4383 5 Minute
Bars 24/02/2005 14:40 through 16/05/2005
21:00. So if the system
being tested is unchanged then each test
should return identical
results. Not so.
Also the problem does not
occur on every run. When it does occur it
affects different
stocks.
Symbols it occurred with included MCD, MLNM, MDT.
Spikes are found by viewing results of tests and finding enormous
gains/losses in equity in a very short time. "Plot on chart" shows
numerous huge spikes (not at opening time). These are also shown on
the Positions tab.
The effect of this is that every test requires
wading through all
the results (for each stock) to identify those
with
"suspicious"
results and then checking each of these stock's
detailed
positions.
This is hugely time-consuming.
Equis have
advised on how to clear the problem. As a follow I have
asked them
a)
how to prevent it occurring.
b) An easy way (non-manual) of identifying
when it has/is happening.
(it is very obvious in a chart but in a system
test or exploration,
it is often only uncovered on delving into the data).
These questions were asked 24/5 and as of today I have not had any
form of response despite a reminder.
Has anyone else had a similar
problem?
