Thresholds from the stock's own history.

Not sure where to set the line? Automatic Alert Setup calculates up to 16 alerts for a stock from its price, volume, borrowing, short, Flow and Reddit history, and shows how often each would have matched. Here it is for NVDA.

Calculating thresholds from history…

Historical matches describe the past, not a forecast. Every suggestion is an ordinary alert you can edit or delete. Automatic Alert Setup needs a free trial or subscription.

Several conditions, one alert.

Group two or more saved alerts and get one alert when they line up, not one for each.

A trigger while a condition holds

The 10:05 sweep is ignored because RSI isn't above 70 yet. The 13:40 sweep arrives while it is, so you get one alert.

Everything within a window

SPY rises 1% at 11:41 and QQQ at 11:52. Both happened within 15 minutes, so you get one alert.

Each alert in the group keeps its own settings; only the combined alert notifies. For two symbols moving together, Paired Move in the Create menu builds the group in one step.

Combined alerts need a free trial or subscription.

Where alerts arrive.

Choose any mix. Every alert is saved, whichever way it reaches you.

Inbox

Each alert with the rule as it was and the data that matched, newest first.

On-site

A notification appears while ChartExchange is open, and the bell in the menu keeps count.

Browser push

Alerts reach your desktop or phone with the site closed. On iPhone and iPad, add ChartExchange to your Home Screen first.

Email

Batched into one message at most every 10 minutes, sent to your account email or another address you verify.

API stream

Every API plan streams your alerts live over WebSocket, as JSON with the rule, the data that matched and when it was delivered. API plans

Every alert, with what matched.

The Inbox keeps each alert with the rule as it was and the data that matched, timed at every step: when the data happened, when the rule matched, and when the alert was delivered. Open one to see.

Questions about alerts.

Short answers. How alerts work has the long ones.

Does a new alert look back at past data?

No. It starts from where things stand when you save it and only fires on what happens after that. Editing an alert resets that starting point.

How often can one alert fire?

At most once per minute. A Combined alert has its own limit, separate from the alerts in it.

What does the free delay mean?

Alerts on a free account and during a free trial arrive 15 minutes after they trigger. On Investor they arrive as they happen.

Can I get alerts on my phone?

Yes, with browser push. On iPhone and iPad, add ChartExchange to your Home Screen, open it from there, and turn on push in the Delivery tab of Alerts.

What happens to my alerts if my subscription ends?

They stay saved. Any alert that needs the subscription pauses, and runs again when access returns.

Where do I create an alert?

From Alerts, or straight from a chart, the Flow tables, the Screener or a stock's data pages, which fill in the symbol and filters you're looking at.

Set up your first alert.

Pick a type, set the condition and choose where it arrives. A free account gets 2 alerts; Investor is free for 14 days.
