# Heikin Ashi Smoothed
# HoboTheClown / blt
# 9.15.2016
# HoboTheClown: I recently found a code for smoothed heiken ashi bars,
# however for some reason all the bars are displayed as one color (going up or down).
#
# blt: Modified the code and replaced the addchart code at the bottom,
# you should now see proper coloring. This is how that was coded to plot
# as an overlay to the chart candlesticks. That is two sets of candles,
# with different coloring for each. If you have the heikin ashi candle
# coloring code on your chart, then they will likely appear the same color.
