SR-ZnV2

There are many support and resistance scripts out there. I was unable to find one that met all of my needs so I have expanded on the closest ones that I was able to discover. The ability to show persistent S/R levels by volume at various time frames automates much of the process for the user with unique and customizable features, the lastest dated of which are displayed by its time frame support/resistance strength and extend toward the right of the screen where they can be seen more clearly by price .
// Original script is thanks to tommyf1001, synapticex and additional modifications is thanks to Lij_MC. Credit to both of them for most of the logic behind this script. Since then I have made many changes to this script as noted below.
// Changed default S/R lines from plots to lines, and gave option to user to change between solid line, dashed line, or dotted line for both S/R lines.
// Added additional time frame and gave more TF options for TF1 other than current TF. Now you will have 4 time frames to plot S/R zones from.
// Gave user option to easily change line thickness for all S/R lines.
// Made it easier to change colors of S/R lines and zones by consolidating the options under settings (rather than under style).
// Added extensions to active SR Zones to extend all the way right.
// Added option to extend or not extend the previous S/R zones up to next S/R zone.
// Added optional time frame labels to active S/R zones, with left and right options as well as option to adjust how far to the right label is set.
// Fixed issue where the higher time frame S/R zone was not properly starting from the high/low of fractal. Now any higher time frame S/R will begin exactly at the High/Low points.
// Added to script a function that will prevent S/R zones from lower time frames displaying while on a higher time frame. This helps clean up the chart quite a bit.
// Created arrays for each time frame's lines and labels so that the number of S/R zones can be controlled for each time frame and limit memory consumption.
// New alert options added and customized alert messages.
