Not taking trades you can't watch through to the exit

This seems obvious, but it's broken all the time. A setup appears five minutes before you need to leave, or just before a call, or right as someone needs your attention. You take it anyway, thinking you'll check on it in a few minutes.

For a scalp, those few minutes are often the whole trade. If the plan involves moving the stop to breakeven at a certain point, or taking partial profits, or exiting if price stalls at a level, none of that happens while you're away. The trade becomes a different trade. It's just entry, stop and target, with no management.

Sometimes that works fine. If your strategy uses fixed stops and targets with no active management, leaving it alone is fine. But if your results depend on managing trades actively, a trade left alone is a trade with a different expected outcome from the ones in your records.

My rule is simple. If I can't commit to watching the whole trade, I don't take it. That includes looking at the clock before entry and estimating how long the trade usually lasts.

If you find many setups appear right when you need to leave, it may help to think about which hours you actually have free and only trade then.

This one is easy to underestimate. We have a simple rule for the desk: no new entry if there are less than 15 minutes before any planned interruption, and if a trade is open when something unexpected comes up, it gets closed or the stop goes to the level we would accept without watching.

The second part matters. Leaving the original stop and target in place sounds fine, but the plan usually counted on active management. A trade without the management is a different strategy, as you say, and that strategy was never tested.

For those with jobs or other commitments, an alternative is to take only trades that don't need management. Set the stop and target, and walk away. This means accepting fixed exits instead of active management for those trades. As long as you know the difference and track those trades separately, it can work. Just don't expect them to perform like actively managed trades. It is a real choice, and a valid one. The key is being honest about which trades fall into this group and judging them by their own results, not mixing them with the actively managed ones.

Mobile apps give a false sense of being able to manage a trade while away. You can see the position and close it, but reacting quickly on a phone while doing something else is hard. Many traders find that their mobile management decisions are worse than their desktop ones. If mobile is your backup, use it for emergencies, not as a normal way to manage scalps. Phone screens also make it harder to see context. Levels drawn on a desktop chart might not show on the mobile app, so decisions are made with less information than you had when entering.

It helps to know the average time your trades stay open. If most of your scalps last fifteen minutes, then a setup ten minutes before you need to leave is a problem. If they last two minutes, you might have time. Looking at the duration column in your history gives you a realistic estimate, which is better than guessing in the moment. Platforms like MT4 and MT5 show the open and close time of each trade, so calculating the average duration is quick in a spreadsheet. Separating it by setup gives even better estimates.

Interruptions during a trade are another version of this. A phone call, a delivery or someone asking you something can pull you away mid trade. Setting up the trading environment so interruptions are less likely during sessions, phone on silent, a closed door, a note that you're busy, reduces the number of trades that end up unmanaged. Telling people in your household when your sessions run makes a difference too. Most interruptions come from people who simply don't know you're in the middle of something. A short message or a sign on the door does more than most traders expect, and it costs nothing to try.
