It is Sunday afternoon, and retail traders are currently performing high-level emotional calculus on whether Fox paying $22B for Roku ($ROKU) means their calls will print on Monday. Across the street, others are staring at the Micron ($MU) chart, convinced that its 293% run-up this year makes it a guaranteed post-earnings breakout on June 24.
The market is closed, yet the anxiety is wide open. You aren't missing trades right now; you are missing preparation. The amateur spent the weekend searching for a hot take to validate their bias. The professional spent it writing down exactly what they will do if their thesis is completely wrong on Monday morning.
Plan the trade before you need the escape hatch.
Then close the spreadsheet and go make dinner.
