A day trade is defined as a round-trip pair of trades within the same day (including extended hours). This is best described as an initial or opening transaction that is subsequently closed later in the same calendar day. For long positions, this would consist of a buy and then sell. For short positions, selling a security short and buying it back to cover the short position on the same day would also be considered a day trade.
An account is designated as a Pattern Day Trader if it makes four (4) day trades within five (5) business days. Day trades less than this criteria will not flag the account for PDT.
Cryptocurrency trading is not subject to the PDT rule. As a result, crypto orders are not evaluated by PDT protection logic and round-trip crypto trades on the same day do not contribute to the day trade count.
Day trades are counted regardless of share quantity or frequency throughout the day. Here are some FINRA-provided examples:

09:30 Buy 250 ABC
09:31 Buy 250 ABC
13:00 Sell 500 ABC
