# HighLow ZigZag

##### New member
I was wondering if someone can set an alarm for me please. I tried many times but didn't succeed. I also noticed it doesn't print the dot right away,can someone hel please. It was posted by someone i can't remember. It would a great piece to add on a chart.

Code:
``````#Begin code
#updated by BonBon - swing_back and _swing_forward (February 4, 2021)
def bubbles = yes;
input swing_back = 45;
input swing_forward = 45;
input maxbars = 50;
input showlevels = Yes;
def sb = swing_back;
def sf = swing_forward;
def na = Double.NaN;

def Offset = 8; # high(period = "day")and low(period = "day" ) and close(period = "day" ) * 0.03;
def bubblelocation = bubbles[Offset];

def lfor = Lowest(low, sf)[-sf]; #Remember that a negative number inside the square brackets means "after" this bar. So, the above line is defining "lfor" as being the lowest value of the two bars after this bar.
def lback = Lowest(low, sb)[1]; #This line of code is defining "lback" as the lowest value of the eight bars before this one.

##############################
#Finally, this line is actually defining what a "swing low" is. It says, if the low of this bar is lower than the two bars after this one AND the low of this bar is also lower than or equal to the lowest of the previous eight bars, then this bar is a swing low.

def swinglow = if low < lfor and low <= lback then 1 else 0;
plot sl = if swinglow then low else na;
sl.SetPaintingStrategy(PaintingStrategy.POINTS);
sl.SetDefaultColor(Color.WHITE);
sl.SetLineWeight(4);

def hfor = Highest(high, sf)[-sf];
def hback = Highest(high, sb)[1];

def swinghigh = if high > hfor and high >= hback then 1 else 0;
plot sh = if swinghigh then high else na ;
sh.SetDefaultColor(Color.WHITE);
sh.SetPaintingStrategy(PaintingStrategy.POINTS);
sh.SetLineWeight(4);

ll);
#End code``````

Solution
as far as alert sounds, this will help

for comparing highs this might help

Code:
``````input barsback = 8;

# check if current high is higher than prev x bars
# these will be 1 or 0 , true or false
def ishigher = ( high > highest( high[1], barsback) );
def islower = ( low < lowest[1], barsback) );``````

then use ishigher as the trigger variable in 1 alert function, and use islower in the other alert.
edit your post by cutting out your code and pasting it back in using code tags. then it will appear in a sub window. click the symbol at top , </> , of the edit post window. read about them from these links.

.......

this is the code i use for alerts.
a higher pitch sound for a signal moving up and a lower pitch sound for a signal moving down.
replace the variables a and b, with your boolean variables. which i'm guessing are swinglow and swinghigh.

Code:
``````#up
#down
#``````

Is it possible to have a high pitch sound for a new (data high) in the last X number of bars and a low pitch sound (like a Gong) for a new low in the last X number of bars. I would appreciate this and I am sure others would also. As I am very new to TOS scripting I have no clue how to start or even if it is possible. Thanks Ahead of time for any help with this great idea.

then use ishigher as the trigger variable in 1 alert function, and use islower in the other alert.
