Setting a stop loss

[maninjapan]

I would like to try and set a stop loss at the most recent Swing low - 1 tick.
Is it possible to do this through the wizard?
So far I have
Position.MarketPosition==MarketPosition.Long
Is this all I need in the 'following conditions are true' section?

I believe this is possible however, it might not be 100% since the swing indicator returns a value of zero or negative (can't recall) which indicates that there is not swing point. The wizard is unable to provide flexibility to check if there is NOT a swing point, use some other value.
