Counting the number of seconds elapsed in a bar

[silvermotion]

Hello,
I am trying to count the number of seconds elapsed in a bar, in PLAYBACK mode with 5 min timeframe.

However, the number of seconds returned is always 0. Can anyone help ?

Hi sivermotion,

What you posted appears to be normal. The time gets updated at the beginning of the bar, so the time will only update every 5 minutes. Meanwhile, you are outputting the time every tick based on bartime.

Here is a code snippet that will work in Playback, I have is set to 3 Seconds. Also be very careful with using debugPrintln. Without clearing the window periodically, the accumulated output is an increasing burden on resources and will really slow things down.


Hope this helps.
