Dave,
This is what I'm trying to do:
-My system requires a different parameter for each stock ie.
different moving averages, different periods used for calculation
etc. Currently I have to use the Param function and interactively
change parameters for each symbol. When I go back to the same
symbol; I would like to use the previous parameters that I have set
to produce the same result I had before. The only way that I know of
right now is to write/store these parameters into an external file in
the harddrive and read them back when I go back to the same symbol.
-I am currently running into problem of AB variable definition and
initialization. I want to have a static kind of variable which store
the symbol and use this to conditionally read in the external file
only a new symbol is read in. I do not have a solution. There might
be other alternative which I would like to hear.
-I have successfully implemented read/write to an external file using
combination of JScript and AFL. Next is how to conditionally steer
the readin or not when the new symbol is entered.
