No alerts on custom script

[drphilgood1358]

Can anyone help me turn either one of the plots at the bottom into an alert that I can send through text. Every time I build it out I get no alerts when triggered on the chart.

input price = close;
input length = 125;
input displace = 6;

plot HMA = MovingAverage (AverageType. HULL, price,length) [-displace];

HMA. DefineColor ("Up", GetColor (1)) ;
HMA. DefineColor ("Down", GetColor (0)) ;
HMA. AssignValueColor (if HMA > HMA[1] then HMA.color ("Up") else HMA.color ("Down") ) ;


def a = hma > hma [1];
def b = hma < hma [1];

plot up = if a and la[1] then high else double.nan;

plot down = if b and !b [1] then high else double.nan;

To get alerts sent to you via text or app notification, you have to build a scanner to scan for the up and down signals. And then save the scanner and select the option "Alerts when scan result change..."
