Because I have finished my exams now !!! YAY !!! Here is my take on finding the change in the price in the last two calendar months of the chart... --8<------------------------------ {Exploration} {ColA - %} theDay:=LastValue(DayOfMonth()); theMonth:=LastValue(Month()); theYear:=LastValue(Year()); {subtract two months} theMonth:=theMonth-2; {roll back years and days as necessary} theYear:=If(theMonth<=0,theYear-1,theYear); leapYear:=Mod(theYear,4)=0 AND Mod(theYear,100)<>0 OR Mod(theYear,400)=0; theMonth:=If(theMonth<=0,theMonth+12,theMonth); theDay:= If(theMonth=4 OR theMonth=6 OR theMonth=9 OR theMonth=11,If(theDay>30,30,theDay), If(theMonth=2 AND leapYear, If(theDay>29,29,theDay), If(theMonth=2 AND leapYear=0,If(theDay>28,28,theDay),theDay))); x:=Year()>theYear OR (Year()=theYear AND (Month()>theMonth OR Month()=theMonth AND DayOfMonth()>=theDay)); y:=x AND Alert(x=0,2); i:=Cum(1)=1; (x>0)*(100*C)/ValueWhen(1, y OR i,C); --8<------------------------------ This will return a percentage change of the last close versus the close of the first bar traded two calendar months ago. Set your filter as required, in this case you want a 190% rise in the period... so --8<------------------------------ {Filter} ColA>=190 --8<------------------------------ I hope you find this useful. Let me know if there are any bugs. ( I have had a few glasses of wine tonight, so expect anything from the code! ) wabbit

I'm trying to get the input from a mouse position or clicks for start and end though so the user can go over the chart and use the mouse to select the start and end points.
