I took the standard Zscore indicator and created an upper indicator out of it that gives buy and sell signals. You can change the sensitivity by going into the code and adjusting the two conditions of -.75 and .75. A closer number to 0 will be more sensitive with more alerts and a higher number will be less sensitive. I don't suggest going over 1.
Below is a picture of ROKU on 9/22/2020 using a 2 min chart. I show the lower indicator as well. The alert is triggered when the Zscore line crosses the average line where the average line is greater than or less than .75. See circled areas. Give it a whirl.
Here is the code:

Here is the code:
Code:
declare upper;
input price = close;
input length = 20;
input ZavgLength = 20;
#Initialize values
def oneSD = stdev(price,length);
def avgClose = simpleMovingAvg(price,length);
def ofoneSD = oneSD*price[1];
def Zscorevalue = ((price-avgClose)/oneSD);
def avgZv = average(Zscorevalue,20);
#Compute and plot Z-Score
DEF avgZscore = average(Zscorevalue,ZavgLength);
#avgZscore.setPaintingStrategy(paintingStrategy.LINE);
DEF Zscore = ((price-avgClose)/oneSD);
#Plot zero line and extreme bands
DEF zero = 0;
DEF two = 2;
DEF one = 1;
DEF negone = -1;
DEF negtwo = -2;
def three = 3;
def negthree = -3;
def condition1 = zscore crosses above avgZscore and avgzscore < -.75;
def condition2 = zscore crosses below avgZscore and avgzscore > .75;
# Plot arrows
plot UArrow = if condition1 is true then 1 else 0;
UArrow.SetDefaultColor(Color.white);
UArrow.SetPaintingStrategy(PaintingStrategy.Boolean_arrow_up);
Uarrow.setLineWeight(4);
plot DArrow = if condition2 is true then 1 else 0;
DArrow.SetDefaultColor(Color.white);
DArrow.SetPaintingStrategy(PaintingStrategy.Boolean_ARROW_DOWN);
Darrow.setLineWeight(4);
