Herman he is talking about automatic analysis. How can you run more
than one formula at a time? AA defines the formula that is being
tested.
You can test more than one system at a time by "forward
testing". I
put my formula in a specially designed bar replay indicator
that will
keep track of the number of positions/shares and the price when
the
trade is made. I run BarReplay and feed 5 second data into the
formula. It tells where the trade is made, the conditions of all the
indicators at the trade, whatever the designer wants to track, and
the
price at the trade. I calculate the gain as each trade is closed.
I post
all of that in the interpretation window. Then you can click
on each
formula and see what the stats are. I also dump this data
into _Trace so
that I can go back later and focus in on a specific
area using DebugView
when it doesn't trade as expected. Tracing more
than one formula is a pain
and I typically use this for debug only.
If you want to check longer
periods you can capture hour or 15 minute
data and feed that into a EOD
chart or weekly chart to see what is
going on in them. The shorter the
period you feed into your formula
the more accurate the results. Let your
imagination run away and you
can test/tweak almost anything this way.
IMO that is more accurate than back testing since you are tracking
the almost true performance of the system. Anyway, that is how I
handle multiple formula analysis at a time.
