Why do the words "BAD HOURS" appear in my charts?

 
I have EUR/USD 5, 15 & 30 minute charts displayed with an EA attached. Can anyone tell me why the words BAD HOURS appear in my 5 and 30 minute charts (not the 15), what it means and whether or not this will have any effact on my EA?

The EA probably has a time to trade programmed?

Interesting thought, however I would have thought that it would appear on all charts/timeframes for the same currency pair??
