Attention is a limited resource, and scalping uses a lot of it. A room with a television, family conversations, or street noise steals some every minute.
The effect is hard to see until the journal reveals it. Sessions in a quiet room tend to have fewer impulsive trades and better rule adherence. Interrupted sessions often show a cluster of mistakes right after the interruption, since attention snaps back and the mind rushes to catch up.
Solutions are simple but need commitment. A closed door and a sign. Noise-cancelling headphones with quiet music or silence. Agreements with housemates about the busiest hours. Phone on silent and in another room.
If the environment can't be controlled, the strategy might need to adapt. Slower setups with longer holding times suit a distracted environment better than rapid scalping.
A cheap diagnostic is tagging each session with a noise rating from one to five. After a month, comparing average results across ratings makes the cost of a loud room visible in numbers rather than hunches.
What interrupts sessions most often, and what did the last interruption cost?
