Won't that potentially cause you to go over the 390 orders/day average and thereby becone a "professional" and lose retail priority and/or your accouny (if the broker can't handle this situation)? I don't know how these dynamic order types work, but I am guessing that if they are broker implemented, the exchanges will treat each update as a separate order, and the number of NBBO price/size changes per day on many options contracts is in 1000's+ per day (even for some that never trade). Would like to be proven wrong on this if anyone else has definite knowledge, thanks!
