Need Alerts For Bull and Bear Strength

[HUJI]

HI Coders, can anyone add an alarm bell or ding to Ben-Tens Trend Channel Indicator for each time there is a crossover on the ZERO line Red to Blue or vice versa at ZERO?

I'm just looking for this to have an alarm when the two signal lines cross exactly on the zero line, I play six stocks at one time and occasionally dose off. Thanks, Greg

declare lower;

def Mdb = simpleMovingAvg(close, 20);
def bull = high - expAverage(close, 13);
def bear = low - expAverage(close, 13);
def upLine = close - Mdb;
def downLine = -(bull + bear);

plot up = upLine;
plot down = downLine;

up.SetDefaultColor(GetColor(6));
down.SetDefaultColor(GetColor(5));

plot ZeroLine = 0;
ZeroLine.SetDefaultColor(GetColor(3));

Thank you, HUJI

Where did the blue line come from? I don't see it in the script.

The blue line is your Trend Channel Indicator, I overlaid the study to see the direction of the
of the stock after my picked scans , but its not in the script I'm asking about
