Breakout strategy indicator and alert

Pretty sure this has already been published here on this site:

Edit: The request does not fit the solution I provided in the link above because the that code merely tracks new intraday high whereas the request is for a close above the previous intraday high. So I am providing a section of code to plot arrows for each bar that closes above the previous intraday high. I have included an alert that will only trigger AFTER that bar has fully closed.

def newDay = GetDay() <> GetDay()[1];
rec trackHigh = if newDay then high else if high > trackHigh[1] then high else trackHigh[1];
plot signal = close > trackHigh[1];
signal.SetPaintingStrategy(PaintingStrategy.BOOLEAN_ARROW_UP);
Alert(signal[1], "Close at New High", Alert.BAR, Sound.RING);
