Hi,

Is there a script to plot a line from 9:30 AM open price and a whole dollar from the open price on Thinkorswim?
Thanks.

Here's an extremely basic script that can accomplish what you want. It should work on any intra-day timeframe. You will want to adjust the color and the PaintingStrategy to match your preferences. Note that if you use an intra-day timeframe > 30 mins that the Open price may not match the open price of your first bar. That's expected since your first bar won't start at the same time as the actual open time.

------------------------
input offset = 1.0;
def aggPeriod = AggregationPeriod.DAY;
def openPrice = open(period = aggPeriod);

plot Data = openPrice;
Data.SetPaintingStrategy(PaintingStrategy.HORIZONTAL);
#Data.SetStyle(Curve.LONG_DASH);
Data.AssignValueColor(Color.LIGHT_RED);

plot Data2 = openPrice + offset;
Data2.SetPaintingStrategy(PaintingStrategy.HORIZONTAL);
#Data2.SetStyle(Curve.LONG_DASH);
Data2.AssignValueColor(Color.LIGHT_GREEN);
-----------------------------
