there are various renditions of codes posted, both here, and else where on the web.

 

a simple search would surely yield heaps of bounty.

Here is a count down timer for Easy Language that only works on an intraday chart. I hacked up that other code, and stripped out a lot of stuff. I got rid of a couple of function calls, and changed where the countdown display is located on the chart. I put it right next to the price bar. That's where I want it.

It looks like TS version 9 has a new way to deal with forcing code to run, which affects countdown timers. Here is a new countdown timer.

I modified the above code. I didn't like the code trying to guess how much time was left in the first bar, so I removed that. And I added text coloring to make the counter red when there is only 5 seconds left in the bar. Also changed the display from the close to the HL2 so it's not jumping around as much, and added some spacing to push it further to the right of the bar.
