//------New V2 Update 07-28-2021----------
//Thanks to @SKTennis for help in Updating code to V2
//Added Groups to Settings Pane.
//Added Color Plots to Settings Pane
//Switched MTF Logic to turn ON/OFF automatically w/ TradingView's Built in Feature
//Updated Color Transparency plots to work in future update
//Added Ability to Turn ON/OFF Show MacD & Signal Line
//Added Ability to Turn ON/OFF Show Histogram
//Added Ability to Change MACD Line Colors Based on Trend
//Added Ability to Highlight Price Bars Based on Trend
//Added Alerts to Settings Pane.
//Customized how Alerts work.  Must keep Checked in Settings Pane, and...
//When you go to Alerts Panel, Change Symbol to Indicator (CM_Ult_MacD_MTF_V2)
//Customized Alerts to Show Symbol, TimeFrame, Closing Price, MACD Crosses Up & MACD Crosses Down Signals in Alert 
//Alerts are Pre-Set to only Alert on Bar Close

//------New V2.1 Update 08-03-2021----------
//Added back in ability to show Dots when MACD Crosses.
//Added Ability to Change Plot Widths in Settings Pane
