unless it can tell you down to the second, how much time is left, I think all you need is a global clock. I mean, if you’re looking at a 5 minute chart, you just have to wait every 5 minutes for a new candle right? I’m not really sure why you would need it to tell you how much time is left.
If you still need it, do a google search for EJ_CandleTime.ex4
You’ll need to put it in your \experts\indicators folder, restart your mt 4, double click on EJ_CandleTime in the custom indicator window and you should be all set.
Its just if i`m watching 4 hour candles, with the clock telling me how long before the next one (at work) i know when the roughly review the charts again.
