You Looked Away
for One Second.
The dog barked. You got up for literally 45 seconds — came back and the chart had already broken down 4%. Your entry was gone. Your stop never triggered.
You went to grab lunch. Set a mental note to check back in 10 minutes. 10 minutes turned into 25 — the position ran without you, reversed, and you missed the whole move.
Or worse — you were watching the whole time, froze on the entry, second-guessed yourself, and the setup played out perfectly without you in it.
