Array input to a strategy?

[Abhijit Dey <omegalist@xxxxxxxxxx>]

I am modifying a strategy to scale out it's position. I want to enter
a) number of contracts to enter the trade with, and
b) scale out n1 contracts as target t1, {n2, t2} and so on.

a) is easy. How to do b? Even if not possible directly, there must be a 
workaround like so many other stuff with TS.

Thanks,

Abhijit
