    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.
