OBJ_TREND extending to the left of chart, not recognizing second time point.
ObjectSetInteger(0,"ORhighline",OBJPROP_RAY_RIGHT,true);
That will just make it extend to the right. I want the line to be a horizontal line, stretching between two specific points in time.
If it is extending to 1970 then your datetime input is incorrect.
Datetime so not string or use StringToTime() function but i don't recommend it.

I'm gonna keep this sweet and to the point. I'm basically just trying to make a little opening range indicator, to practice. I've got a trendline, that is supposed to stretch from the high of the ORcandle, to the same price a few hours later. The problem is, it is plotting the first point just fine, but the second point it is not. the second point is being put at the right price, but checking the properties of the drawn trendline, it is extending to the far left of the chart ,sometime in 1970, instead of at 20:00 like it's supposed to. You can also see that I made sure that it was set to not be a ray. I just need to know why it is not recognizing my second time input.
