This is from the on-line help file, I think it addresses your questions: Changing Indicator Parameters The Quotes Plus Scan Database Program uses default values when calculating certain indicator functions such as MACD(), MACDSignal(), ROC(), Stochastic(), and RSI(). Using the SET command, a user can now change these default values. A user can use the Display Charts program to visually see what will happen to an indicator when these default values are changed. Select the Indicator | Options menu selection to change the default indicator values from within the Display Charts program. Function: MACD(), MACDSignal() Set MACD=<Small MA>, <Larger MA>, <Signal MA> Changes the default value used in the MACD calculation. The default value for the length of the Shorter MA periods is 12, length of the Longer MA periods is 26, and the length of the Signal MA periods is 9. Example: Set MACD = 8,17,9 //Change the defaults for MACD AllGroup MACD(0) > MACDSignal(0) MACD(-1) < MACDSignal(-1) This example will change the default indicator options from 12, 26, 9, to 8, 17, 9 before calculating the MACD() and MACDSignal() functions. Function: ROC() Set ROC=<ROC Periods> Changes the default value used in the ROC calculation. This will change the number of ROC periods from 12 to the value the user specifies. Example: Set ROC = 14 AllGroup ROC(0) > 0 ROC(0) < ROC(-1) Selects issues that have a ROC above the central line but is declining, which indicates that the price is still above its level 14 days ago but the difference between the two readings is shrinking. This may indicate a bearish factor. Function: Stochastic() Set STOCHASTIC =<%K Value>,<%D Value> Changes the default values used in the Stochastic calculation. The default %K Value is 14 and the default %D Value is 3. Example: Set STOCHASTIC = 16,5 Stochastic(0) > 80 //Over bought on a daily basis Function: RSI() Set RSI =<RSI Length> Changes the default value used in the RSI calculation from 14 to what the user chooses. A 14-day period calculation for RSI is recommended, but some people argue that a 22-day span is more accurate. A 9-day span works well for very short term movements. Example: Set RSI=22 Comment = "High RSI" RSI(0) >= 60 MovAvg(0,150,cl) <= MovAvg(-9,150,cl) Close(0) >= 10 //At least a 10 dollar stock
