// bug warning...there is a glitch in the display lines which only seems to respond to 
// having all the line thicknesses preset and not compiling the indicator after it is attached.
// if compiled after attaching to chart the line widths go screwy and will not follow the code.
// my suggestion is to keep all line width settings as they are preset and not compile after attaching.
// Reattach as needed to reset line widths.
