About

NTP Candle Timer

Read full description

A clear candle countdown beside your charts. NTP Candle Timer is a timing utility for stock, futures, forex and crypto traders. Watch the time remaining in a repeating interval without covering your trading platform. NETWORK-TIME SYNC The app periodically compares device time with network time and applies the measured offset to its display. The final 15 seconds show hundredths of a second. Actual accuracy can vary with the network, device and your trading platform's time source. The app does not change your device clock. YOUR INTERVAL, YOUR DISPLAY Choose 1, 3, 5, 15, 30 or 60 minutes. Use landscape or portrait orientation, select a font and color, and optionally show the battery indicator. AN OPTIONAL REFERENCE CLOCK Display Local, New York or UTC time below the countdown. New York follows daylight saving time automatically. This option is off by default and does not change the countdown or the timezone of your market alerts. VISUAL AND SOUND ALERTS Choose warning colors, final-seconds sounds and a session-end sound. Set market open and close reminders in your device's local time. Keep the app open during your session; it is not a background alarm service. The core timer and reference clock are free with banner advertising. An optional auto-renewable subscription removes banner ads and unlocks Pulse and Afterglow visual effects. The app interface supports English, Korean, Japanese, Spanish, Portuguese, German and French, following your device language preferences. Other languages fall back to English. NTP Candle Timer does not provide prices, trading signals, brokerage services or financial advice. Verify critical timing with your trading platform. Payment is charged to your Apple Account at purchase confirmation. Subscriptions renew automatically unless canceled at least 24 hours before the end of the current period. Manage or cancel subscriptions in your Apple Account settings.
