Now that I'm digging into the trade specific variables, what I may need is the average profit of all open trades. Does TradeProfit give that? How does TradeProfit behave when more than one trade is open?

Here is an example:

You go long 1 lot at 100.
You add to your position, an additional lot, at 110.

What would be the value of TradeProfit when the asset is trading at 120?
Would it be 30 (total profit)?
15 (average profit)?
10 (the profit of the most recently opened trade)?
Other?

Thanks!
