## A fixed price is arbitrary

Set an alert at “$50” and you’ve picked a number that means something today and nothing next month. A stock sitting at $50 after crashing 20% is in a completely different situation than one sitting at $50 after rallying 20% — same alert, opposite story.

A **percentage alert** fixes this by measuring _change_, not a static level. “Up 5%” or “down 8%” means the same thing regardless of what the stock happens to cost right now.

## But percentage from what?

This is the part most alert tools skip. “Up 5%” is meaningless without a reference point:

Baseline

Good for

Opening price

Intraday moves, day-trading style watching

Weekly average

Short-term trend shifts, filters daily noise

Monthly average

Medium-term pullbacks/rallies

Quarterly average

Longer structural shifts, ignores short-term volatility

A watcher that lets you choose (and change) the baseline is what turns “percentage alert” from a gimmick into something you’d actually trust to replace manually checking a chart.

## Stacking conditions instead of chasing every tick

The other failure mode of percentage alerts is noise — get pinged on every 1% wiggle and you’ll mute the app within a week. Layering conditions (e.g. “up 5% vs the month **and** above the opening price”) means you only hear from it when multiple signals agree, which is a much stronger indicator than any single threshold alone.

## Bottom line

If you’re choosing between a fixed-price alert and a percentage alert: percentage almost always wins, but only if you can control what it’s a percentage _of_. That’s the piece worth checking for before picking a tool.
