Trend line & pivot level

This script can plot pivot levels and trend lines that are haven't broke out.
In the setting, left and right means how to get the pivot. the pivot will be gotten based on the left candles and the right candles. boxes will be auto deleted after the box was broke.
Important: This is just a beta version, if you find some bug with using this script. Don't hesitate to contact me.
What the future version will have? Might be pattern scanner, multi trend line, levels in different time frame, break out alert, or better key level algorithm. Depends on when I have free time.
