One thing to keep in mind is that if you plan to use other boxes to
run optimizations, they will need access to price data.
If you are using free data (e.g. Yahoo, Google) this is not an issue
as you can just install the data on each box.
Similarly, if you plan to use IO, this is a non issue since IO copies
the data from the client to the servers.
However, if you are using a paid subscription for your data, your
license may not allow you to have the data on more than 2 machines.
You might have to make a special request to your vendor, or buy
additional licences.
Alternatively, you might be able to set the AmiBroker database on
each box to point to a single location of the data over a network. I
haven't tried this, so don't know if it works. The drawback is that
the hosting machine would always need to be on when any of the other
boxes needed access, you couldn't update the data while another box
was trying to use it, you increase your odds of messing up the data
by having multiple access points to it (i.e. if you mess up your
database from one machine, you will have messed it up for them all),
etc, etc.
