Ray Bull/Bear Power Combo For ThinkOrSwim


After reading this thread I was interested in combining Ray Bull Power and Ray Bear Power as I trade both long and short near equally.

Perhaps someone may find this useful.
declare lower;

# Ray component

input bullLength = 13;
input bearLength = 13;
plot zeroline = 0;

def Bull = high - ExpAverage(close, bullLength);
def Bear = low - ExpAverage(close, bearLength);

def bullOver = if bull > zeroline then bull else double.nan;
def bullUnder = if bull < zeroline then bull else double.nan;
def bearOver = if bear > zeroline then bear else double.nan;
def bearUnder = if bear < zeroline then bear else double.nan;

plot minorBullPower = if bearOver then bearOver else double.nan;
plot BullPower = if bullOver then bullOver else double.nan;
plot minorBearPower = if bullUnder then bullUnder else double.nan;
plot BearPower = if bearUnder then bearUnder else double.nan;

declare lower;

input length = 20;
input bullper = 13;
input bearper = 13;

def Mdb = ExpAverage(close, length);
def bull = high - ExpAverage(close, bullper);
def bear = low - ExpAverage(close, bearper);

plot upLine = close - Mdb;
upLine.AssignValueColor(if upLine > 2.0 then CreateColor(0,102,204) else Color.CURRENT);

plot downLine = -(bull + bear);
downLine.AssignValueColor(if downLine > 2.0 then Color.RED else Color.CURRENT);

plot centerLine = 0;

Thanks for this indicator. How do we decide about Buy or Sell? can you provide the code for scanner?
try this for Bull movement
def length = 20;
def bullper = 13;
def bearper = 13;

def Mdb = ExpAverage(close, length);
def bull = high - ExpAverage(close, bullper);
def bear = low - ExpAverage(close, bearper);

def upLine = close - Mdb;
def downLine = -(bull + bear);

plot crUp = upLine crosses above downLine;

#plot crDn = upLine crosses below downLine;

for bear scan comment (#) plot crUp and uncomment crDn and create another scan
