#DayTradingStrategy Day trading refers to a trading strategy in which a person buys and sells (or sells and buys) the same security in a margin account on the same day in an attempt to profit from small price fluctuations in the security. The FINRA margin rule for day trading applies to any security, including options.

Intraday trading is not allowed in a cash account. All securities purchased in a cash account must be paid for in full before selling. In a cash account, according to FINRA rules, buying a security, paying for it in full as required by Regulation T, and then selling it is not considered intraday trading.
