Join →Day Trading: Trading Within the Trading Day
Day trading means opening and closing our positions within the same trading day, so we normally do not carry the position through the regular overnight period. The important point is not the label itself, but the decision framework it creates: we are trying to capture an intraday price movement while controlling execution risk, transaction costs, and the temptation to overtrade.
What We Are Actually Trading
A day trader is not simply a trader who uses a short chart. We can trade a five-minute chart while making decisions from a one-hour context, or use a fifteen-minute setup and execute on a one-minute chart. The defining feature is the holding horizon. Our thesis should therefore have a reason to work during the current session rather than requiring several days to develop.
What Makes a Day-Trade Setup Useful?
- Context: we identify trend, range, volatility and important price levels before looking for an entry.
- Catalyst or reason for movement: a session open, breakout, news event or strong momentum can create the opportunity, but is not a guarantee.
- Defined invalidation: before entering, we know what price action would tell us that the idea is wrong.
- Execution: spread, liquidity and slippage matter because the expected move can be small relative to trading costs.
Risk and Position Management
Intraday trading can produce many opportunities, but that does not mean we should take many trades. We define the maximum acceptable loss before entry and size the position accordingly. If our stop is relatively tight, a small change in position size can materially change the monetary risk. We also have to account for correlated positions: three trades on highly related technology stocks may behave more like one large exposure than three independent trades.
Example
Suppose a liquid stock opens above the previous day’s range and holds that level after the first pullback. We can define the opening range, wait for a retest, and enter only if the market confirms the level. Our stop sits at a point that invalidates the setup rather than at an arbitrary percentage. If the expected move to the next resistance does not offer enough reward relative to the planned risk and costs, we skip the trade.
Common Failure Modes
Typical problems include chasing the first large candle, increasing size after a loss, taking marginal setups late in the session, and continuing to trade simply because we have time available. A professional process treats no trade as a valid outcome.
