Syntax for variable instruments

[raz0rback]

Hi guys.

I have a strategy with multiple instruments.

Currently the instruments are hard coded with:

Add("ZN 12-08", PeriodType.Tick, 1);

How can I code it so that the date "12-08" is replaced with a variable string that I can modify in the parameters. I know how to set up a user defined input. Just dont know how to code the Add() line.

Cheers

Unfortunately this is not supported.

Let's say your date is a string in the configuration parameters. The variable is expirationDate. Couldn't you just do:

Add("ZN" + " " + expirationDate, PeriodType.Tick, 1);

I'm working on the same problem, but I have indexes & commodities and they don't all have the same expiration dates so it's even more complicated.

Does "not supported" mean it has been tested and doesn't work, or you do not answer questions if we try it?

I don't see any reason why it wouldn't work but I haven't tried it myself.

It likely won't work.
