The Rules of Engagement
US pattern day trader (PDT) rules require $25,000 equity to make more than three day trades per five sessions in a margin account. Cash accounts escape PDT but settle trades T+1, limiting recycling of capital. Day trades generate short-term gains taxed at ordinary income rates, and commissions/spreads compound: a hundred round trips at a few cents of spread each is real money.
What Day Traders Actually Trade
Liquid, volatile instruments: index futures and options, large-cap momentum names, gappers on news. Strategies cluster into breakout trading, VWAP reversion, and news scalping — all requiring fast execution, level-2 familiarity, and pre-defined risk per trade (professionals commonly risk 0.5-1% of account per idea, exactly like a betting unit).
The Survival Statistics
Peer-reviewed studies across multiple markets converge grimly: the large majority of day traders lose money, and consistent multi-year profitability is measured in single-digit percentages. The edge that exists belongs to preparation, risk control and specialization — treat any 'system' sold with lifestyle screenshots as entertainment. If you must try: paper trade first, then size so that a 50-trade losing streak is survivable.
