Price vs. MA Indicator - Need Some Help

   I would like to create an indicator that measures the percentage difference between the current price vs. a moving average, say the 50 DMA.  It would be similar to the Price ROC indicator in the BC indicator list except that it would compare the current price to a MA instead of a price X days ago.  If price = 50 DMA, the indicator would be at 0.  If the price was above the 50 DMA by 19%, it would register +19 above the zero line.  There would be 0-100 above and 0-100 below the 0 line.  Should be pretty simple, but I know nothing about coding/programming/scripting but would like to know what statements I would have to use to convert the existing PROC indicator to do this.  Any help would be greatly appreciated.

	Hi ken, Percentages are very useful in trading that's for sure. [Description="Deviation Percent, Max"] expr := expression("Expression"); method := inputma("Method",S); period := input("Time period",20,1); average:= ma(expr,period,method); ((expr - average) / average) * 100; [horzline=0]

	Another use of percent is identifying support and resistance areas and profit targets. [Description="Percentage Bands, Max"] [Target=Price; lineStyle=Solid; color=steel blue] P50:=ma((HHV(C,50) + LLV(C,50))/2,5,E); P50; [lineStyle=Dotted] P501.05; { 5% above & below } P500.95; P501.10; { 10% above & below } P500.90;
