## 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

1.  Pick the ticker (stock or ETF).
2.  Set the threshold: **down 5%**.
3.  Pick the baseline: opening price, weekly average, or monthly average.
4.  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.
5.  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.
