NinjaTrader uses a number of different properties of the TradeStation generated email to identify unique orders as they are sent to NinjaTrader.

They are:

• Instrument name
• Action (Buy, Sell etc...)
• Signal name
• Workspace name

If you are running concurrent strategies on the same market you should ensure that you either -

• Make all signal names unique or
• Run the concurrent strategies in different TradeStation workspaces

This will ensure accurate processing of your automated signals.
