Accessing MarketPosition from Indicator Script

[TAJTrades]

I am trying to create a little Indicator Script that will substitute NT's "Plot execution | TextandMarker" chart option with a Line drawn on the chart showing Trade Entry and Trade Exit. I do not auto trade so using a Strategy File may not be the answer.

I tried using the Help File example for "MarketPosition" and get the following Error:
Indicator\TradeTracker.cs An object reference is required for the non-static field, method, or property 'NinjaTrader.Cbi.Position.MarketPosition.get' CS0120 - click for info 53 10

I tried using the Help File Example for "IPosition " and get the following Error:
Indicator\htcTradeTracker.cs 'NinjaTrader.Indicator.htcTradeTracker.OnPositionU pdate(NinjaTrader.Cbi.IPosition)': no suitable method found to override CS0115 - click for info 36 25


Are "MarketPosition" and "IPosition" only allowed in Strategy Files? If so, how can I get around this. Or what am I missing to access Trade Data from within an Indicator File? Have I missed a Using Declaration?

Thanks.

TAJTrades, correct, this would work in strategy context only and only relative to the individual strategy you're working with as strategies do not cross communicate.

Accessing your discretionary added positions via NinjaScript is unfortunately not supported.
