Here is the Squeeze Indicator Code that everyone has asked about that Rob Chastain from Think Or Swim Michigan Office coded for the TOS platform. The code to be inserted into the Think Or Swim platform follows:

declare lower; # shows up on bottom

Input Length = 20; # Length for Avg  True Range & Std. Dev Calcs

Input Price = Close; # type of price to use

Input minPriceMove = 1;  # for scaling

Input priceIncrement = 0.01;

Input nK = 1.5; # Keltner Channel ATRs from Average

Input nBB = 2; # Bollinger Band Std. Devs. from Average

Input AlertLine = 1; # BBS_Index level at which to issue alerts

Input SqueezeOnColor = 2;

Input SqueezeOffColor = 6;

# scaling factor :

def LHMult = if (priceIncrement <> 0, (minPriceMove/priceIncrement), 0);

# Average True Range

def ATR = AvgTrueRange(high, close, low, Length);

# Standard Deviation

def SDev = stdev(Price, Length);

# — Calculate Bollinger Band Squeeze Indicator –

# for alert

def Denom = (nK*ATR);

def BBS_Ind = if (Denom <> 0, ((nBB * SDev) /Denom), 0);

# — Plot the Index & Alert Line ————————-

plot BBS_Index = 0;

BBS_Index.assignValueColor(if BBS_Ind < Alertline then Color.Red else Color.Blue);

BBS_Index.SetStyle(4);

BBS_Index.SetLineWeight(2);

# ——————————————————–

# — Plot delta of price from Donchian mid line ———-

# Inertia = LinearRegValue

def LinearRegValue = Inertia(price-((Highest(high, Length)+Lowest(low, Length))/2 + ExpAverage(close,Length))/2,Length);

#Plot the Green Values

def LRVGreens = if (LinearRegValue >= 0, LinearRegValue, 0);

plot BBSqueeze_Pos = LRVGreens * LHMult;

BBSqueeze_Pos.SetPaintingStrategy(PaintingStrategy.HISTOGRAM);

BBSqueeze_Pos.assignValueColor(if LRVGreens > LRVGreens[1] then Color.Green else Color.Dark_Green);

BBSqueeze_Pos.SetLineWeight(2);

#Plot the Red Values

def LRVReds = if (LinearRegValue < 0, LinearRegValue, 0);

plot BBSqueeze_Neg = LRVReds * LHMult;

BBSqueeze_Neg.SetPaintingStrategy(PaintingStrategy.HISTOGRAM);

BBSqueeze_Neg.assignValueColor(if LRVReds < LRVReds[1] then Color.Red else Color.Dark_Red);

BBSqueeze_Neg.SetLineWeight(2);

#Show Alert Dots

# SQUEEZE ON

def BBS_CrossOverAlert = if (BBS_Ind > BBS_Ind[1] and (BBS_Ind > AlertLine) and (BBS_Ind[1] < AlertLine), (LRVGreens * LHMult + 150  * minPriceMove), 0);

plot CrossOverAlert = if BBS_CrossOverAlert > 0 then BBS_CrossOverAlert else Double.NaN;

CrossOverAlert.SetPaintingStrategy(PaintingStrategy.POINTS);

CrossOverAlert.SetLineWeight(4);

CrossOverAlert.assignValueColor(Color.Light_green);

CrossOverAlert.assignValueColor(GetColor(SqueezeOnColor));

#    Alert(”BB Squeeze Alert”);

# SQUEEZE OFF

def BBS_CrossUnderAlert = if (BBS_Ind < BBS_Ind[1] and (BBS_Ind < AlertLine) and (BBS_Ind[1] > AlertLine), (LRVReds * LHMult - 150  * minPriceMove), 0);

plot CrossUnderAlert = if BBS_CrossUnderAlert < 0 then BBS_CrossUnderAlert else Double.NaN;

CrossUnderAlert.SetPaintingStrategy(PaintingStrategy.POINTS);

CrossUnderAlert.SetLineWeight(4);

CrossUnderAlert.assignValueColor(GetColor(SqueezeOffColor)); # Color.Light_red);

#    Alert(”BB Squeeze Is Over”);
