Day trading
buying and selling financial instruments within the same trading day
Day trading is a form of speculation in securities in which a trader buys and sells a financial instrument within the same trading day. This means that all positions are closed before the market closes for the trading day to avoid unmanageable risks and negative price gaps between one day's close and the next day's price at the open. Traders who trade in this capacity are generally classified as speculators. Day trading contrasts with the long-term trades underlying buy-and-hold and value investing strategies. Day trading may require fast trade execution, sometimes as fast as milli-seconds in scalping, therefore direct-access day trading software is often needed.
Day trading is a strategy of buying and selling securities within the same trading day. According to FINRA, a "day trade" involves the purchase and sale (or sale and purchase) of the same security on the same day in a margin account, covering a range of securities including options. An individual is considered a "pattern day trader" if they execute four or more day trades within five business days, given these trades make up over six percent of their total trades in the margin account during that period. Pattern day traders must adhere to specific margin requirements, notably maintaining a minimum equity of $2,000 in their trading account before engaging in day trading activities.
Day traders generally use leverage such as margin loans.

Why this record matters
“Day trading” is worth following because a concise public description often conceals a longer documentary argument. Here, trading, buying and selling provides the most credible route into that argument.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jul 21, 2026. The linked authority identifier is Q1064131. The Library of Congress control number is sh99011019. 1 of 1 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
