The market keeps office hours too

Yes, if you can give a fixed, uninterrupted window of the US session to trading. For some time zones that's easy. For others it means before dawn or late at night.

The hard part isn't the hours on paper. It's that a day trade needs your eyes from entry to exit. A stop that triggers on a candle close only works if someone is watching the close.

To make it work, stop trying to catch everything. Pick one window you can protect and ignore the rest of the session.

The version that fails is trading in the gaps between meetings. You check a phone under the desk and exit late because a call ran over. The math below shows which window you actually have.

US stocks trade from 9:30 to 16:00 New York time, six and a half hours. Here's that session in other zones.

Pacific time: 6:30 to 13:00. A 9-to-5 worker gets the first two hours before work. Central time: 8:30 to 15:00, so only the first half hour is free. Eastern time: the whole session sits inside a normal workday.

London: 14:30 to 21:00 most of the year. Leave work at 17:30 and you get the last three and a half hours. Central Europe: 15:30 to 22:00. Finish at 17:30 and you get the last four and a half hours.

Watch the clock changes. The US moves its clocks a few weeks before Europe in spring and a week later in autumn. In those weeks the session opens an hour earlier for Europe. That's 13:30 in London and 14:30 in Paris.

Choose the window your life can protect every day, then make it the only time you trade. For West Coast traders that's often the open. For Europe it's usually the afternoon session.

Write the window down with a hard stop time. If you have 90 minutes before work, the last entry might come 30 minutes before you leave. That leaves time to manage the trade to its exit.

Draw your levels the evening before, not in the window itself. That turns the session into execution, not analysis.

If you must step away with a position open, decide first how you'll handle it. A resting stop order with your broker protects you while you're gone. It can also fill on a wick that a close-based exit would have ignored. Pick the trade-off on purpose, before you're in the trade.

Split attention costs money twice. You enter late because you were in a meeting, then you exit late because the meeting ran over.

A day trade is short. Missing ten minutes can mean missing the whole move, or sitting through a stop you'd have taken.

There's a second risk that has nothing to do with charts. Some employers restrict personal trading or the use of work devices for it, especially in finance. Read your contract and your company's policy before you open a chart at your desk.

Then look at your own record. If your results get worse on days you traded around meetings, the window is wrong. A trade log with hold times shows this quickly. Losers held far longer than winners often mean exits waited on something else.

If your free time falls after the close, swing trading fits better than day trading. You read daily charts in the evening and place orders for the next day.

Decisions happen on a daily close, which you can check at night. Nothing needs watching at 11 in the morning.

The cost is overnight risk. A stock can open well past your stop on news, and a close-based exit can't help with that. You manage it with smaller size, not with screen time.

A sensible order is to start here while you're employed. Move to day trading once you can protect a daily window. That lets you build a record without fighting your calendar every morning.

Keep the same discipline you'd use intraday. Write the level, the stop and the target before you place the order, then let the daily close decide.

Don't quit on a good month. A short run of wins tells you very little. Here's what to check first, with real numbers from your own record.
