an Exploration to do position sizing. Another example is that I need
to pass values to an AFL to overwrite Param value. One more example
is that an AFL needs to know from which JScript it is invoked and
then behave differently. As you said, we can use file to pass data.
In fact that's what I am doing now. However, it is becoming more
cumbersome when you do it a lot and the code becomes not as clean as
I would like it to be. So, it would be natural to use
StaticVarSet/Get instead. AFL engine has supported StaticVarSet/Get
as a means to record states and pass data between different runs. It
is very logical to enable AA Object to do so.
