Alert when current price is specified percent from high or low of day

Since you asked for an indicator or an alert I chose alert and moved this out of the Chart Studies topic and into the Alerts and Notifications topic.

The way I would do this for a chart study is not the same as I would do it for a study alert or scan. So I will provide code that will work as a Study Alert or a Scan.

The following code is to be applied to any of the intraday time frames supported for Study Alerts or Scans:

input percentThreshold = 4.0;
def newDay = GetDay() <> GetDay()[1];
rec trackHigh = if newDay then high else if high > trackHigh[1] then high else trackHigh[1];
rec trackLow = if newDay then low else if low > 0 and low < trackLow[1] then low else trackLow[1];
# use this to scan for current price specified percent below the high
plot scan = close < trackHigh * (1 - percentThreshold * 0.01);
# use this to scan for current price specified percent above the low
#plot scan = close > trackLow * (1 + percentThreshold * 0.01);
