Louis,
You are welcome, I am very happy to be of assistence.
As far as backtesting sentiment data, it is pretty straightforward.
Download the data off the internet, and import it into Ami as a
textfile. You can then use it in backtests as you would any other
instrument. Do a google search on 'sentiment data' and you will find
a wealth of information.
If you are interested in trading forex, I forgot to mention that
OANDA offers near real-time snapshots of aggregate client positions.
I experimented with this data at one point and found to my suprise
(well not really) that the small OANDA traders are pretty bad as a
group. You can use this data as another source of research ideas if
that interests you (I shelved the project myself to focus on
equities). I remember I tested something like either buying or
fading breakouts based on which way the small-money was leaning, and
found pretty good if preliminary results from that. It is definitely
an interesting avenue for you or someone else out there, I believe.
I can share with you a few of my models, so if you want send me an
email we can talk more. However, I highly recommend you spend a few
days (or more) googling on your own for the resources I discussed in
my last post. You should really want to take ownership of this
process as much as you can. It won't be easy at first, but once you
build a foundation, hopefully a certain type of trader's intuition
will start to kick in for you. You'll know it when you feel it, is
how I can best describe it.
