Day Trading

What it is

Opening and closing all positions within a single session.

Day trading concentrates a whole trading career into single sessions. Because everything is closed by the bell there is no overnight gap risk, but there is also no time for a thesis to recover — the market either agrees with you within hours or it does not. Activity and execution conditions vary across assets, sessions and events. Compare a dated sample instead of assuming that one universally best hour establishes an edge.

Market conditions that matter

Good days have a clear opening drive, expanding range and volume above the recent average. Bad days are narrow, overlapping and volume-starved — typically the sessions before a major holiday or the day before a central-bank decision, when institutions stand aside. Learning to recognise a no-trade day is worth more than any additional indicator.

Best suited to

Full-time traders. Anyone who has at least 3 hours of focused screen time.

Badly suited to

Learners whose schedule cannot support the chosen observation window.

The steps

• Define a session window for the worksheet and compare its actual volume, spreads and events with other windows.
• Use the 5-min chart with VWAP.
• Use a deliberately small and consistent simulated risk budget, and set a session limit that you can evaluate afterwards.
• Close everything before the close — no overnight exposure.
• End every day with a journal entry: what worked, what didn't, what to cut tomorrow.

Worked example

Hypothetical worksheet, not an observed trade: Long SPY at VWAP reclaim, stop below VWAP, target the day's prior high.

The numbers behind it

Hypothetical arithmetic: fixed realized 52% wins at 1.5R and 48% losses at 1R give 0.30R gross expectancy. An arbitrary 0.5% of $100,000 is $500, so expectancy is $150 per trade and $750 across five trades before costs. This is an input-based worksheet, not observed returns or a slippage estimate.

How it fails

• Trading the midday lull out of boredom. Range contracts, stops get hit by noise, and the day's profit from the open is handed back.
• Using a fixed dollar stop instead of a structural one. The stop should sit where the idea is wrong — below VWAP, below the opening range — not at an arbitrary loss you find comfortable.
• Ignoring the daily loss limit. Two full stops in a session is a signal to close the platform; a third is almost always emotional rather than analytical.

Practising Day Trading safely

When reviewing a Day Trading practice trade, compare the rule you planned with the action you recorded. The first pitfall above is a useful review question:

Trading the midday lull out of boredom. Range contracts, stops get hit by noise, and the day's profit from the open is handed back.
