//@version=3

//Created by user ChrisMoody updated 4-10-2014
//Regular MACD Indicator with Histogram that plots 4 Colors Based on Direction Above and Below the Zero Line
//Update allows Check Box Options, Show MacD & Signal Line, Show Change In color of MacD Line based on cross of Signal Line.
//Show Dots at Cross of MacD and Signal Line, Histogram can show 4 colors or 1, Turn on and off Histogram.
//Special Thanks to that incredible person in Tech Support whoem I won't say you r name so you don't get bombarded with emails
//Note the feature Tech Support showed me on how to set the default timeframe of the indicator to the chart Timeframe, but also allow you to choose a different timeframe.
//By the way I fully disclose that I completely STOLE the Dots at the MAcd Cross from "TheLark"
