There are quite a few fantastic complex options strategies that could be used if brokers would allow traders to submit orders of greater than 4 legs at once. Unfortunately at this stage it seems to be impossible to capitalize on these opportunities because of this limit on trading opportunities. Allowing traders to execute, for example, 2 butterflies simultaneously on one order, to be filled AON, opens up new possibilities and variants on strategies that cannot currently, realistically achieve success because the necessity of legging in (and the risk it presents) destroys the strategy before it begins. Anyone else agree?
