How to add chart based study alert (Fib retracement)

Hi Mr. Hahn. First of all thank you for all your help. I use a script that plots Fibonacci retracement levels and I wanted to know if it was possible to add an alert when the price reaches or goes below the 78.6 level and when the price goes above the high. Below is the script. Thanks

def length = 1;
def na = Double.NaN;

#def DayHigh = HighestAll(high);
#def DayLow = LowestAll(low);
def DayHigh = HighestAll(high);
def DayLow = LowestAll(low);
plot dh = DayHigh;
plot dl = DayLow;

def hi = GetMaxValueOffset(high);
def lo = GetMinValueOffset(low);

# HI AND LOW VALUES
def hitime = GetMaxValueOffset(DayHigh , length);
def lotime = GetMinValueOffset(DayLow , length);
def updown = if hitime >= lotime then 1 else 0;

# FIB DEFINITIONS
def ud23 = If ( updown, 0.214, (1 – 0.214));
def ud38 = If ( updown, 0.382, (1 – 0.382));
def ud61 = If ( updown, 0.618, (1 – 0.618));
def ud78 = If ( updown, 0.764, (1 – 0.764));
def ud1130 = If ( updown, 1.13, (1 – 1.13));
def ud1236 = If ( updown, 1.236, (1 – 1.236));
def ud1382 = If ( updown, 1.382, (1 – 1.382));
def ud1618 = If ( updown, 1.618, (1 – 1.618));

# FIB PLOTS
plot uFib50 = (DayHigh – DayLow) / 2 + DayLow;
plot uFib786 = (DayHigh – DayLow) * ud23 + DayLow;
plot uFib618 = (DayHigh – DayLow) * ud38 + DayLow;
plot uFib382 = (DayHigh – DayLow) * ud61 + DayLow;
plot uFib23 = (DayHigh – DayLow) * ud78 + DayLow;
#plot uFib1130 = if showExtended is false then na else (DayHigh – DayLow) * ud1130 + DayLow;
#plot uFib1236 = if showExtended is false then na else (DayHigh – DayLow) * ud1236 + DayLow;
#plot uFib1382 = if showExtended is false then na else (DayHigh – DayLow) * ud1382 + DayLow;
#plot uFib1618 = if showExtended is false then na else (DayHigh – DayLow) * ud1618 + DayLow;
