how to identify whether a negotiation is a purchase or a sale?

[fabiobioware]

I have an EA that is sending information externally, and I want to send information that identifies whether the current negotiation is a purchase or a sale.

How do I do this?

@fabiobioware Do you mean you are using a copier? Many commercial copiers already do that. Otherwise I'm not sure what do you exactly want. Do you need the 'launcher' EA tells the 'copier' EA if a trade is a buy or a sell?

@l-andorrà I am making a personal copier.
Yes, I need exactly this information.

@fabiobioware Wow. That means using terminal variables. I have no idea how to do that, sorry.
