This is another 'non-traditional' options spread that can be set up in the ORATS backtester by adjusting the Leg Relationships section.

Next change the Leg Relationships as the way it is set now with a min max of 0 to 0 will produce no results. Make the min max large so you don't need to think about it like -99 to 99.
