I thought I'd fill my time between trades by getting GROK and myself to code a Candle Time indicator as well as a Multi Time Frame Open Prices indicator, incorporating all the options that other indicators I've used lacked.

1) Display vertically or horizontally.

2) Individual colours for each selected time frame.

3) Progress bars showing candle countdown.

4) Individual colours for progress bars.

5) Precise adjustments of candle time display

6) Individual alerts for each candle time frame.

7) Selectable time frames all in one indicator

8) Dynamic progress bar adjustment based on the highest selected time frame.

9) Individual sounds (alerts) for each selected time frame

Enjoy
