Simultaneous Positions

[SystemTrading]

Is it possible to have a simultaneous long and short position on the same instrument?

Not from a single instance of a strategy.

What if I used the Add() method to add a second instrument in the strategy. Could I then buy instrument 1 and sell instrument 2 simultaneously?

If they are different instruments you can.

An additional clarification...what happens in a simple moving average crossover strategy where
1. 'crossabove' is used to enter long (at the same time the same crossabove is used to exit the short trade)
2. and 'crossbelow' is used to enter short, but at the same it is also used for exiting the long trade.
So in this situation, for example, I am assuming the long trade is exited and short trade is entered on the same bar.
Will this work? And does it violate the internal order handling rules?
Are there any nuances dangers which I should be aware of?
thanks

This would not be the way you want to do it. For reversals all you have to do is call your entry order. NinjaTrader will automatically handle the reversal and close your prior position for you. Going EnterLong with ExitShort can cause overfills and thus should not be done.
