Hello again,
I'm back with a bit of a different take on the Opening Range. This is a relatively simple indicator that analyzes movement during a specified time period and plots various lines based on that information. I am anchoring a VWAP (with standard deviations) to this start time as well to better judge the prevailing trend. The opening range is usually a daytrading tool and as such this will not display on daily or higher timeframes. There is another similar concept based on the weekly open range but that is a topic for another time.
In the image above, I have added the study twice. Once, from the European session open and once from the US Open. You will see the blue-ish lines representing the opening range for each of those periods with a mid-line and some extended targets based on the range. This study is intended to provide context to your trading system but is not a strategy in and of itself. If you are interested in learning more about why Opening Ranges are important and some different strategies to trade them, there is a more complex study with background information here: Opening Range Breakout.
There are options in this study to show the range as a label in the top left, to show/hide the extended targets and also to add additional 1/4 and 3/4 lines inside of the range. You can also enable bubbles to show that display the OR highs and lows but need to have an expansion area of 5 bars or so to display properly. And finally, there is an option to color your candles if they fall outside of the OR.
The options have two associated timeframes. One for the opening range you want to analyze (eg. 9:30 to 9:45) and another for the period for the lines to draw (eg. 9:30 to 16:00). In the image above, the first version has 2:30 to 3:30 as the European open range and 2:30 to 9:00 as the time to draw the lines. The second version (in the same chart) is 9:30 to 9:45 and then 9:30 to 16:00 for the line display. Hopefully this makes sense.
This study will work best on timeframes less than 1 hour and will perform will on tick charts. Range charts and renko charts will have some difficulties with the study and the VWAP will not work on those at all. This one was pretty fun to build. Please let me know if you have ideas for improvement.
