# Limit the add bubble of low or high of a candle when compared to market open candles (high and low) to only once during market time

##### New member
The code given below detects low or high of a candle when compared to the market open candle. I need some help in limiting the detection to only once during market open. Here is the code.

input marketOpenTime = 0930;
input marketCloseTime = 1600;
def closeByPeriod = close(period = "DAY")[-1];
def openbyperiod = open(period = "DAY")[-1];
def secondsFromOpen = secondsFromTime(marketOpenTime);
def secondsTillClose = secondsTillTime(marketCloseTime);
def marketOpen = if secondsFromOpen >= 0 and secondsTillClose > 0 then yes else no;

def newDay = if !IsNaN(closeByPeriod) then 0 else 1;

def referenceBarLow = if secondsTillTime(0930)==0 then low else referenceBarLow[1];
def lowerLowThanOpeningBar = if secondsTillTime(0930)!=0 then low < referenceBarLow[1] else 0;

def referenceBarHigh = if secondsTillTime(0930)==0 then high else referenceBarHigh[1];
def higherHighThanOpeningBar = if secondsTillTime(0930)!=0 then high > referenceBarHigh[1] else 0;

addchartbubble(marketOpen and higherHighThanOpeningBar, high, "H", COLOR.GREEN);

Any help is much appreciated.

which one time do you want to find?
the first occurrence after the first bar? the highest high of the day? the last occurrence?

The first occurrence after the mark open candle bar (either high or low is breached of the market open candle - only one).
