Good question, it uses the Tradier API so you would still need to trade 4+1. But once filled you can add the individual leg to the 4 legged spread combo to correctly follow its performance.
I am working on a function where you can build the 5 legged spread that we are trading now and the app would automatically seperate it in two orders. Once filled they combine in the portfolio. Same for closing. But this still needs a bit of testing so I’m sure it’s stable and working as intended.
