Hello, I would like to know how to build a specific spread instead of the build ones. For example, If I would like to do a spread but with different leg calls or puts resulting on 4 legs or 5 legs, some legs with a 2 or 3 ratio some short, some long, and different DTE. Is this possible? and how? I tried with iron condor, unbalanced butterfly, and ratios, but it was not possible to do credit on one side and debit other legs, also I tried with synthetics and it sent the orders separately instead of on one spread. Could you help me please, thanks.
