Grantx 

Can anyone help me out here? I am trying to set the starting point of a line to a specific date and time. If I set my DateTime object to a date, how do I get Tool.BeginDateTime to accept it as a date?

SCDateTime GrantxDateTime;
GrantxDateTime.SetDateTime(2019, 06, 07, 10, 39, 0);

Tool.BeginDateTime = GrantxDateTime;
Tool.EndDateTime = sc.BaseDateTimeIn[DrawingIndex];

mkata 

SCDateTime GrantxDateTime; GrantxDateTime.SetDateTime(2019, 06, 07, 10, 39, 0); Tool.BeginDateTime = GrantxDateTime; Tool.EndDateTime = sc.BaseDateTimeIn[DrawingIndex];

Works

Had to use .SetDateTimeYMDHMS(2019, 06, 07, 14, 39, 0);

Thank you!

Hoping someone can help me out here. I am attempting to modify the 'High/Low for time period' study.
If I set the study to show the 1st hour of the US opening range, then it plots higher and lower lines on the chart. I would like the study to also reflect the difference between the high and low of that opening range.

You can see in the attached images what I mean. One image shows the standard study settings and the other one shows it with the text I am trying to add.

Here is the modified code. Everything I have added is commented with 'My stuff'.
You can see right at the bottom I calculate the high and low but then I dont know why the study does not add that data to the chart? I have added the drawstyle as text but why aint it showing?
