[amibroker] trading hours vertical lines and day of the week

[gsmservplus]

hello,
sorry i`m not a AB programer or AFL guru, but how can i get together with 
vertical lines between days in intraday,month in EOD we`ve got now,separate 
vertical lines for trading hours.eg. i`d like to have one line in different 
color at 9.30a.m. and one line at 16:00 in hourly,5-min. or 1-min charts.
and one more thing. any chance to have a day of the week(eg. 
Mon,Tue,Wed,Thu,Fri) together with the dates we`ve got now on the standard AB 
charts?
thanks
