Charting futures butterfly & condor spreads

[CB001]

Would it be possible to create a script to calculate and chart futures butterfly or condor spreads?

There's an indicator posted to the forum for charting futures calendar spreads, so perhaps it's as simple as modifying the code's input formula from the difference of front month's ask & deferred/'back' month's bid (if buying the calendar), to the front month's ask minus twice the 'middle' month's bid plus the back month's ask.

Any preliminary considerations for starting with this notion? Any input appreciated.

Welcome to our forums CB001 - correct, I think the spread indicator approaches could be serving as good starting point for further custom works in this area changing the formula to calculate with the two inputs series as you desire.
