Above the line, or below it.
LineAlert watches your tickers and tells you the day the 8-day EMA crosses the 20-day EMA. One list, one arrow per stock, one push when it flips.
Coming to the App Store Questions
What it does
Fast EMA is above the slow EMA. Trend is with you.
Fast EMA is below the slow EMA. Trend is against you.
Pro checks every close at 4:05pm ET and pushes the flip to your phone, app closed or not.
Six months of closes with both lines and a marker at each cross, so you can see how the line has treated that stock.
What it doesn't do
No accounts. No news. No trading. No intraday noise: the line is computed on daily closes only, so one alert per real change, not twenty per afternoon.
Pricing
Free: up to 3 tickers, alerts when the app refreshes in the background.
Pro, $3.99/month or $29.99/year: unlimited tickers and same-day push alerts after the close.
Your settings
Periods are adjustable (default 8 and 20). Bring your own Twelve Data key if you want a licensed feed on the free tier; it stays in your iPhone's Keychain.
LineAlert is a math tool, not investment advice. Prices are end-of-day and may be delayed or wrong.
