Day Trading — Trading Wiki

What Day Trading means

Opening and closing all positions within a single trading day. No overnight risk. Requires significant screen time, discipline, and capital. 90% of day traders lose money.

In depth

Day trading is the practice of buying and selling financial instruments within the same trading day, closing all positions before the market closes to avoid overnight risk and gap risk. Day traders profit from intraday price movements using technical analysis on shorter timeframes (1-minute to 1-hour charts) and typically execute multiple trades per day. The allure of day trading lies in its perceived potential for rapid wealth creation, but the reality is sobering. Multiple academic studies and broker-disclosed data consistently show that approximately 70-90% of retail day traders lose money over any given year.

A comprehensive study by the Brazilian Securities Exchange Commission found that 97% of futures day traders who persisted for more than 300 days lost money, with the average daily loss exceeding the Brazilian minimum wage. These statistics are remarkably consistent across markets, time periods, and geographies. Successful day traders typically share several characteristics: they have sufficient capital (the US Pattern Day Trader rule requires $25,000 minimum account equity for frequent day trading), they treat trading as a full-time profession with dedicated screen time during market hours, they have a statistical edge from a well-tested strategy, and they maintain rigid risk management discipline.

The per-trade risk is typically 0.25-0.5% of account — smaller than swing trading due to the higher number of trades. Common day trading strategies include momentum trading (buying assets making new highs on heavy volume), scalping (taking small profits from many trades), mean reversion (buying oversold assets and selling overbought ones), and gap trading (trading the opening gap between previous close and current open).

Practical tip

Before risking real money, day trade on a simulator for at least 3 months while tracking every trade in a journal. You need a minimum 200-trade sample size to determine if your strategy has a genuine edge or if early profits were just luck.

Why it matters when you are learning

Day trading looks glamorous but is one of the hardest professions in finance. Start with swing trading and graduate to day trading only if you're consistently profitable.

Practising Day Trading on the simulator

Reading about Day Trading and using it are different skills. Try it once in the simulator on an instrument you already follow, write down beforehand what you expect to happen, and check the journal a day later to see whether it played out that way. Educational simulation only — not financial advice.
