Hi guys,I'm trying to work out how to set up a custom indicator that would show me the standard deviation of a set of macd plots.The four macd plots are( XAVGC5 - XAVGC13 - XAVG(XAVGC5,5) + XAVG(XAVGC13,5) ) ( XAVGC13 - XAVGC21 - XAVG(XAVGC13,5) + XAVG(XAVGC21,5) ) ( XAVGC21 - XAVGC34 - XAVG(XAVGC21,5) + XAVG(XAVGC34,5) ) ( XAVGC34 - XAVGC55 - XAVG(XAVGC34,5) + XAVG(XAVGC55,5) ) I've found the formula on here to calculate a standard deviation as SQR( ( ( C*C + C1*C1 + ...+ Cn*Cn )- ( p * AvgCp * AvgCp ) ) / n )where p = SMAPds and n = Pds-1However, I don't understand what all the variables in this formula signify or how to create it as a pcf/ custom indicator. Any help with this would be greatly appreciated.Regards Steve

What's the Period of the Standard Deviation you wish to apply?

Hi Bruce,I want the standard deviation to be daily. I'm trying to measure the deviation between the four macd indicators for each day.Regards Steve

You are normally going to calculate Standand Deviation on a data series over a period of time. This is the Period that was requested. If you are looking for something based not on a time series for each of the MACD Histograms, but using the values of the four MACD Histograms as the four values used in a 4-Period Standard Deviation instead, you might wish to try the following:
Select Chart Template | Add Indicator | Indicator
-Visible: Checked
-Center Zero Line: Unchecked
-Plot Using Price Scale: Unchecked
-Smoothing Average: 1
-Smoothing Type: Doesn't matter (because the Smoothing Average is 1)
-Indicator Formula: SQR(ABS((XAVGC5 - XAVGC13 - XAVG(XAVGC5,5) + XAVG(XAVGC13,5)) ^ 2 + (XAVGC13 - XAVGC21 - XAVG(XAVGC13,5) + XAVG(XAVGC21,5)) ^ 2 + (XAVGC21 - XAVGC34 - XAVG(XAVGC21,5) + XAVG(XAVGC34,5)) ^ 2 + (XAVGC34 - XAVGC55 - XAVG(XAVGC34,5) + XAVG(XAVGC55,5)) ^ 2 - 4 * ((XAVGC5 - XAVG(XAVGC5,5) - XAVGC55 + XAVG(XAVGC55,5)) / 4) ^ 2) / 3)
