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. Most of the day's directional movement happens in the opening 90 minutes and the final hour, which is why disciplined day traders trade those windows and stay flat through the low-volume midday drift.

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

Part-time hobbyists — fatigue + emotion = death.

The steps

• Trade only the first 90 minutes and the last 60 minutes of the session.
• Use the 5-min chart with VWAP.
• Risk ≤0.5% per trade, max 5 trades per day.
• 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

Long SPY at VWAP reclaim, stop below VWAP, target the day's prior high.

The numbers behind it

A 52% win rate at 1:1.5 gives (0.52 x 1.5) - (0.48 x 1) = +0.30R per trade. Five trades a day at 0.5% risk on $100,000 is $250 risk per trade, so roughly $375 of expected value a day before commissions and slippage — and slippage on market orders in fast conditions is routinely a quarter of that. Track your actual fills in the simulator's journal rather than assuming the mid-price.

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 it safely

Run this method for at least thirty simulated trades with fixed sizing before judging it, and record every trade in the journal. A handful of winners proves nothing. Educational simulation only — not financial advice.
