Updated script to plot vertical lines for open and close of .
Not sure why the 8:30 and 15:00 times had to be used over 9:30 or 16:00
Only plots for products of type . - Could be easily expanded to work with cryptos as well if you wanted.
In true TradingView spirit, the author of this script has published it open-source, so traders can understand and verify it. Cheers to the author! You may use it for free, but reuse of this code in a publication is governed by House Rules. You can favorite it to use it on a chart.
