Sorry, I figured he was messing around with their app like me. I use RH, actually did decent on Thursday and Friday jerking with FB puts than calls. Not the fastest app so seeing someone hit over 300 orders was eye opening. Perhaps, on my most bored and self loathing day I hit 100 orders.
It wasn't me. The post circulated a number of option discussion boards. It becomes a real concern, not only from a standpoint of fees and data costs. Some exchanges don't provide visible size for pro customers. You should check your broker routing and limits if you are declared pro. I should have been clearer in the original.
They probably mail like five of those annually, and that largely was due to a 100 sigma health event.
