It went like this: pds:=Input("Normalizing lookback periods (1= historical Hi/Lo)",1,2600,150); { Plot 1: Price section } PriceX:=C; { Choose x pds or historical Price High/Low } Hi:=If(pds>1,HHV(PriceX,pds),Highest(PriceX)); Lo:=If(pds>1,LLV(PriceX,pds),Lowest(PriceX)); { Price normalized to 0~100% } PriceNorm:=(PriceX-Lo)/Max(Hi-Lo,.000001)*100; { Plot 2: Indicator/Oscillator section } IndX:=WillA(); { Choose x pds or historical Indicator High/Low} Hi:=If(pds>1,HHV(IndX,pds),Highest(IndX)); Lo:=If(pds>1,LLV(IndX,pds),Lowest(IndX)); { Indicator normalized to 0~100% } IndicatorNorm:=(IndX-Lo)/Max(Hi-Lo,.000001)*100; { Plot in own window } {PriceNorm;IndicatorNorm} (IndicatorNorm-PriceNorm)/25 This works perfectly on daily data but, for some reason, when I use the formula in explorer to sift through intrday data I always get an overflow error message. I've tried to modify it but nothing seems to work. Any chance you could help again?

I think I did a bad job explaining the problem. The problem is not the daily or intraday plots....the oscillator plots well in daily AND intraday format. The problem is when I use it in the explorer to search for setups. It routinely rejects all of my intraday searches and gives the folling reasons: Security Name Reason for Rejection Location DJ06M*60 Error in column A: Invalid time period (zero or negative) passed to HHV() function. C:\MSdata\MsdataFES DVY*60 Error in column A: Invalid time period (zero or negative) passed to HHV() function. C:\MSdata\MsdataFES ES06M*10 Error in column A: Invalid time period (zero or negative) passed to HHV() function. C:\MSdata\MsdataFES ES06M*30 Error in column A: Invalid time period (zero or negative) passed to HHV() function. C:\MSdata\MsdataFES ES06M*60 Error in column A: Invalid time period (zero or negative) passed to HHV() function. C:\MSdata\MsdataFES GLD*60 Error in column A: Invalid time period (zero or negative) passed to HHV() function. C:\MSdata\MsdataFES NDX.X*10 Error in column A: Invalid time period (zero or negative) passed to HHV() function. C:\MSdata\MsdataFES NDX.X*60 Error in column A: Invalid time period (zero or negative) passed to HHV() function. C:\MSdata\MsdataFES SPY*10 Error in column A: Invalid time period (zero or negative) passed to HHV() function. C:\MSdata\MsdataFES * * * * * * I suspect it may have something to do with the amount of intraday data I have and the parameters of the formula. I get my intraday data from quote.com and I think I only get about 200 bars of data per issue. I tried modifying the "pds" variable, but I can't seem to get any results. Thanks again for any assistance. Jim | |
