Separating the unrealized gain for two trades in the same strategy

[galsermil]

I need to calculate the unrealized P&L for more than 1 position in the same strategy. It is my understanding that <Position> calculates all open trades in a strategy. I have been assigning the unrealized gain/loss of the first trade to a variable and then subtracting from the total when there are two trades but this seems awkward and I'm wondering if there is not a better way?

Hello galsermil,

There is only one position per instrument in a NinjaScript Strategy. (There is also one position per instrument per account)

Multiple trades would affect the quantity and average price of that single position. Meaning a buy order at 100 and a second buy order of 110 would result in a position of long 2 with an average price of 105.

Are you meaning that you have different instruments added with AddDataSeries()?

Each instrument added with AddDataSeries() that has a position will be in the Positions collection.

A trade has both an entry order and an exit order. So if this is a trade, the orders of that trade would not affect the open position as that position is now closed with the exit order of that trade.
The trade would then be in the SystemPerformance TradeCollection.

The Position.GetUnrealizedPnl() (or Positions[series index].GetUnrealizedPnL()) will only return the unrealized pnl of the open position. (Where there is an entry order but no exit order)
You could add this to the SystemPerformance of closed trades.
Below is a link to an example.

Chelsea, I was doing my best to not confuse the issue but obviously I did not succeed. In a single instrument I have two entries and no exits. I need the Unrealized profit for each transaction separately as the targets for each are different.

Hello galsermil,

NinjaTrader does not track unrealized pnl for each individual order, only the position.

You will need custom coded logic to save the orders to a variable or array, and compare the current price to the entry fill price and calculate with the fill quantity.

The orders will update in OnOrderUpdate().
