Stock Alert Apps Compared: Yahoo Finance, Fidelity, TradingView, and Onepage.live
The question behind this page
“What app do you recommend for price alerts — like % changes, reoccurring?” is one of the most common questions in stock-trading communities, and the honest answer is: it depends what you mean by “alert.” A fixed-price ping, a percentage move, a one-time notification, or something that keeps checking after it fires are four different features, and most tools only do one or two of them well. This page compares the tools people actually recommend for this, including Onepage.live — made by us, so judge the framing accordingly, but we’ve tried to be specific about tradeoffs rather than just picking a favorite.
Quick comparison
| Alert type | Baseline options | Fires again after triggering | Cost | |
|---|---|---|---|---|
| Yahoo Finance Watchlist | Fixed price | None — static number | No | Free |
| Fidelity (native brokerage alerts) | Fixed price, % since close, 52-week high/low, EMA cross | Several, but only if you hold the position at Fidelity | Varies by alert type | Free with a Fidelity account |
| TradingView | Fully custom (indicators, Pine Script, drawn conditions) | Whatever you configure | Configurable, but alert count is capped on free/lower-tier plans | Free tier limited; paid plans from ~$15–60/mo |
| Onepage.live | Percentage change from a baseline | Opening price, previous close, 7/30/90-day average, 52-week high/low, custom | Yes, by default | Free to start |
Yahoo Finance Watchlist
The most-recommended free option, and a fine choice if you want broad market data and news alongside a simple watchlist. Its alerts are fixed-price only and stop once triggered — see the full comparison for detail on both limitations.
Fidelity (and similar brokerage-native alerts)
If you already hold the position at Fidelity, its built-in alerts are genuinely capable — percentage-since-close, 52-week high/low, and moving-average-cross options go further than most free tools. The catch is that it’s tied to holding the position there: it’s not a general-purpose watcher for tickers you’re tracking but don’t own, or for comparing alerts across multiple brokerages in one place. If your accounts are already at Fidelity, this is a reasonable native option; if you want one tool across everything you watch regardless of where (or whether) you hold it, that’s the gap a dedicated alert tool fills.
TradingView
The most powerful option by far if you’re already doing chart-based technical analysis — custom indicators, Pine Script conditions, drawn trendlines. That power comes with setup cost for a simple case (“ping me at 5% from the opening price”), and free/lower-tier plans cap how many alerts you can have active at once. See the full comparison.
Onepage.live
Built narrowly around one thing: percentage moves from a baseline that actually means something (opening price, a moving average, a 52-week extreme), checked continuously rather than as a one-time trigger. Less powerful than TradingView, not tied to a specific brokerage the way Fidelity’s alerts are, and — unlike Yahoo Finance — a watcher keeps firing every time the condition is true, not just the first time.
Which one fits your setup
- Want broad market data and news, alerts are secondary: Yahoo Finance.
- Already hold the position at Fidelity and want a quick native option: Fidelity.
- Doing real technical analysis on charts and want alerts wired into that: TradingView.
- Want a simple, recurring, baseline-anchored percentage alert that isn’t locked to a brokerage or a chart setup: that’s what Onepage.live is built for specifically.
