The problem with “alert me at $47”
Most free stock alert tools only do one thing well: tell you when a price crosses a fixed number. That’s fine the day you set it. It’s useless a month later, because the stock has moved and $47 doesn’t mean “down 5%” anymore — it might mean down 15%, or up 3%.
If what you actually want is “tell me when this drops 5%”, a fixed-price alert can’t do that on its own. You’d have to recalculate the number and re-set the alert every time the baseline changes.
What “5% down” should actually be measured against
A 5% drop only means something relative to a starting point. The starting point you pick changes what the alert catches:
- From the opening price — catches an intraday move, useful for short-term/day-trade style watching.
- From the weekly average — filters out single-day noise, catches a real shift in the week’s trend.
- From the monthly average — catches a slower, more significant pullback, ignores short-term wobble.
Most tools force you into one of these. A watcher that lets you pick the baseline (and combine more than one) gives you a 5%-drop alert that stays accurate without manual upkeep.
Setting it up
- Pick the ticker (stock or ETF).
- Set the threshold: down 5%.
- Pick the baseline: opening price, weekly average, or monthly average.
- Optionally stack a second condition — e.g. “down 5% from open AND below the monthly average” — so you only get pinged when both are true, not on every dip.
- Save the watcher. It runs quietly in the background and pings you the moment the condition fires.
No spreadsheet, no manually recalculating a new fixed price every week.
