Choppiness Index Indicator for ThinkorSwim

Very useful indicator, Thanks!
Can someone pls assist in modifying the code, so the choppiness plot turns color(input default yellow) when it exceeds the specified choppy level and reverts to original color when chop level falls below the threshold.
If possible, plot a vertical band of chosen color, indicating the choppiness band, when the chop level is above the chop threshold.

something like this :

This is the code I have, from this thread:

Code:
===========
# Choppiness Index
# UpTheCreek
# 09.21.2015
# V 1.0

# Choppiness Index was developed by Australian commodity trader E.W. Dreiss
# and may be used to determine if the market is consolidating or trending.
# The Choppiness Index is a directionless indicator. Values above the upper
# guide (61.8) indicate that the market is moving sideways in a ranging or
# choppy manner. Values below the lower guide (38.2) indicate the market is
# trending.
#
# The CI measures the relationship between the Sum of daily trading ranges
# during a given period of time against the total range for that period.
# Low readings in the CI correspond closely with the end of strong impulsive
# movements either up OR down, while High readings occur after significant
# consolidations in the price. Extended periods of trendless price movement
# are reflected in extended periods of above-average readings of the CI.
#
# Bill Dreiss says "high CI readings can be used to indicate that a
# consolidation is about to end and a position should be entered or a
# breakout anticipated. Since the CI reading has nothing to do with market
# direction, it does NOT indicate in which direction to expect the breakout,
# but that the breakout will probably be followed by a significant move.)
# In this respect, the CI is similar in usage to Bollinger Band width (%B).
#
# Commodity Traders Consumer Report, July/August, 1992, Bill Dreiss “The
# Fractal Wave Algorithm, Charts And Systems”
#
# CI is similar to ADX where values below the 38.2 line coincides with ADX
# values above 20 which show a trending market. The author Driess preferred
# his solution over ADX.

declare lower;
input length = 14;
input UseLabels = yes;
Input Choppy_Level=61.8;
Input Trend_Level=38.2;

def Hmax=highest(high, length);
def Lmin=lowest(low, length);

plot choppiness = 100* log(sum(truerange(high, close, low),length)/(Hmax-Lmin))/log(length);
choppiness.SetDefaultColor(Color.BLUE);
choppiness.SetLineWeight(2);

plot choppy=Choppy_Level;
choppy.SetDefaultColor(GetColor(2));
choppy.SetLineWeight(2);
choppy.SetStyle(Curve.POINTS);

plot trending=Trend_Level;
trending.SetDefaultColor(GetColor(6));
trending.SetLineWeight(2);
trending.SetStyle(Curve.POINTS);

AddLabel(UseLabels && choppiness > choppy, "Consolidating, watch for break", Color.RED);
AddLabel(UseLabels && choppiness < trending, "Trending, watch for chop", Color.DARK_GREEN);

# End Study

Any ideas? Thanks!
