FAQ

Do reminders run on a server in the background?

No. The countdown and sound run only in the currently open browser page. Closing or refreshing the page loses the current reminder state.

Can I edit preset trading sessions?

Yes. Presets are only starting points. You can add, delete, or edit any session. Check exchange or broker information for holidays, temporary changes, and product-specific sessions.

How does 15K calculate reminder times?

The tool starts from each session start time and adds 15-minute steps, creating bar-close reminders such as 09:45 and 10:00. Cross-midnight night sessions automatically move early-morning reminders to the next date.

Why should I click test sound first?

Browsers usually require a user click before a page can play audio. Testing sound confirms the current browser allows the alert tone.
