[amibroker] Re: Help needed on a simple code:

["nebt1" <nebt1@xxxxxxxxx>]

Hi David,
Thanks for your suggestion. It certainly better that what I had 
before. Just one more thing needed:
yesterday high and low lines appearing on today chart from 9:30 till 
16:00. I would like those lines to start appearing say at 7:45 in 
case there are premarket news or there is a gap open in the morning
and we need to see yesterday high/low ahead of time.
For example my yesterday close line starts at 16:00 yesterday time 
and keep going till 16:00 today:

marketclosetime= deValueWhenTime(O, 160000);
Plot
(marketclosetime, "",colorCustom10,styleDots+styleNoLine+styleNoRescal
e);

So wondering how to make those two lines (yesterday high and low) to 
start appearing from 7:45 today time.
Regards, Tom
