Find Your Best Trading Hours by Analyzing Results by Time of Day

For many day traders, a large share of the profit comes from a small part of the day. The rest of the session often gives some or all of it back. Analyzing your results by entry hour is one of the fastest ways to improve, because the fix is simple: trade more in your good hours and less in your bad ones.

Why time of day matters

Market behavior changes through the session. In US stocks, for example:

• The open usually has the most volume and the biggest moves. Opportunity is high, and so is risk.
• Late morning often sees trends continue or reverse as the opening moves settle.
• Midday is typically quieter, with lower volume and more choppy, range-bound price action.
• The last hour often brings volume back as funds adjust positions into the close.

Your personal results will depend on your style. A breakout trader may thrive at the open. A mean-reversion trader may do better at midday.

How to run the analysis

1. Group all your trades by the hour you entered.
2. For each hour, look at the number of trades, total P&L, win rate and average R.
3. Ignore hours with very few trades. Ten trades is not enough to conclude anything. See sample size.

Look at both total P&L and average per trade. An hour with many small losing trades can quietly cost more than one big loss.

What to do with the results

• A clearly losing window: stop trading in it for a month and see what happens to your results. Many traders find their P&L improves just by stepping away at midday.
• A clearly winning window: make sure you are fully prepared for it. If your best hour is the first one, your pre-market routine matters even more.
• No clear pattern: fine. Not everyone has one. Check day of week and holding time instead.

Check holding time too

A related question is how long you hold. Some traders make money on trades held 5 to 30 minutes and lose on trades held for hours, often because they let losers run. Look at P&L by holding time next to time of day.

In TradeThink

The reports page breaks results down by entry hour, weekday, month and holding time, with the number of trades for each bucket, so you can see at a glance where your edge is. Use filters to check whether the pattern holds for each setup separately.
