amibroker intraday charts

I am using amibroker 5.5 . It shows chart with white background and hollow n filled candles.:mad: How to change it with black background and green n red candles. please help :confused:

Can someone please advise me what all settings need to be done as regards to the timings in Intraday setting button? At present I have set it as 9:15-3:30. But the problem I am facing is that my 5 minutes candles are closing before time. So my candles are closing at 9:19, 9:24,9:29 etc.
