The count this follows
Under FINRA Rule 4210, a customer who makes four or more day trades within five business days in
a margin account is a pattern day trader, provided those day trades are more than six percent of
the account's total trades over the same period. A flagged account needs at least 25,000 dollars
of equity to keep day trading. FINRA has proposed changing these requirements, so check the
current rule and your broker's policy, and remember that brokers can apply stricter definitions.
The counter moves a five-business-day window across the dates you enter, skipping weekends and
any holidays you list, and reports the most day trades inside any one window. It also shows the
latest window, the one that ends on your most recent day trade, and the business day after which
its oldest trade stops counting.
What counts as a day trade
Buying and selling the same security in the same margin account on the same day is a day trade,
and so is selling short and covering the same day. How several buys and sells in one session
are counted can depend on the order they happen in, and brokers apply their own counting, so
use your account's day trade counter as the final word. For the full rule, see
pattern day trader; for trading without it,
day trading in a cash account.
