Trading strategy “zero” for scalpers

I would like to tell you about a trading strategy for scallers with zero commission, which is used only by a narrow number of market participants, those who have no brokerage commission at all. I must say right away that zero commissions are available only to NYSE members, i.e.. brokers, etc.. It's not a secret for anyone that besides a specialist in the market (NYSE, NYB) there is still a lot of ECN (NASDAQ, ARCA, WHEREAS, BATS and others), that's just with the help of them you can earn. It's only about that way, which I used and we will talk about BATS. Theory of trading strategy Let's start with the theory of what trading at zero looks like in general.
