Intraday trading means opening and closing positions within the same trading session, finishing flat or nearly flat. Its raw material is the day’s range — opening momentum, midday turns, closing moves — read on minute-scale charts.
How it works
Decisions arrive in sequence: dozens of signals, entries, and exits per week, each judged on short timeframes where the day’s structure unfolds.
Because nothing is held overnight, gaps and after-session news do not touch the account — but every round-trip cost is paid at full weight against thin targets.
Why it matters
Cost share is the defining constraint: a fixed spread and fee bill takes a much larger fraction of a 0.3% target than of a 5% one.
Execution discipline dominates: speed, slippage control, and the ability to stop after losses matter more than reading any extra indicator.
A simple market example
A day trader buys a breakout at 10:05, exits at 10:40 for a 0.4% gain, and pays a 0.25% round-trip cost. Half the day’s prize went to participation — repeated across the month, that share decides the account.
Common mistakes
Treating frequent intraday signals as frequent opportunity. Most short-timeframe movements are noise with a pattern’s shape.
Assuming intraday works everywhere: some markets restrict same-day round trips or require specific account types.
Frequently asked questions
Is intraday trading more profitable than longer styles?
Not inherently. It compounds opportunity faster and costs faster too — results depend on edge net of costs and execution discipline.
Why do so many intraday beginners lose?
The usual combination: thin targets, full-price costs, and decisions taken too fast to review. The style punishes small execution errors.
Does intraday trading require watching the screen all day?
Mostly yes — the style’s risk control lives in real-time decisions. Leaving a fast position unattended is holding, not intraday.
