I think you'll need some more beer, Sportrider - your code doesn't plot any High/Low signals (only one of each allowed per month) as shown in this sample chart. jose '-)

When i put into my Metastock 9.1 Pro for E-Signal in the Indicator Builder to a New Formula Creation the: --->Start---> Days:=Cum(1); DaysLoaded:=LastValue(Days); DaysRemaining:=DaysLoaded-Days; StartOfMonth:=(Month()>Ref(Month(),-1)) OR (Month()=1 AND Ref(Month(),-1)=12); Months:=Cum(StartOfMonth); MonthsLoaded:=LastValue(Months); MonThsRemaining:=MonthsLoaded-Months; EndOfMonth:=(Month()<Ref(Month(),1)) OR (Month()=12 AND Ref(Month(),1)=1); HighDaysAgo:=If(EndOfMonth,HighestSinceBars(1,StartOfMonth,HIGH),0); LastHigh:=LastValue(HighestSinceBars(1,StartOfMonth,HIGH)); LowDaysAgo:=If(EndOfMonth,LowestSinceBars(1,StartOfMonth,LOW),0); LastLow:=LastValue(LowestSinceBars(1,StartOfMonth,LOW)); DaysPassed:=BarsSince(StartOfMonth); LastDay:=LastValue(DaysPassed); DaysLeftInMonth:=If(MonthsRemaining>0, LastValue(ValueWhen(LastValue(MonthsRemaining+PREV-PREV), Endofmonth,DaysPassed)),LastDay)-DaysPassed; currenthigh:=If(MonthsRemaining>0, LastValue(ValueWhen(LastValue(MonthsRemaining+PREV-PREV), EndOfMonth,HighDaysAgo)),LastHigh); currentLow:=If(MonthsRemaining>0, LastValue(ValueWhen(LastValue(MonthsRemaining+PREV-PREV), EndOfMonth,LowDaysAgo)),LastLow); HighDay:=If(DaysLeftInMonth=Currenthigh,1,0); LowDay:=If(DaysLeftInMonth=CurrentLow,-1,0); HighDay; LowDay; <---End<--- I received the Message: This constant is being used incorrectly But when put the above Formula in the same Field without the --->Start---> and <---End<--- meaning: Days:=Cum(1); DaysLoaded:=LastValue(Days); DaysRemaining:=DaysLoaded-Days; StartOfMonth:=(Month()>Ref(Month(),-1)) OR (Month()=1 AND Ref(Month(),-1)=12); Months:=Cum(StartOfMonth); MonthsLoaded:=LastValue(Months); MonThsRemaining:=MonthsLoaded-Months; EndOfMonth:=(Month()<Ref(Month(),1)) OR (Month()=12 AND Ref(Month(),1)=1); HighDaysAgo:=If(EndOfMonth,HighestSinceBars(1,StartOfMonth,HIGH),0); LastHigh:=LastValue(HighestSinceBars(1,StartOfMonth,HIGH)); LowDaysAgo:=If(EndOfMonth,LowestSinceBars(1,StartOfMonth,LOW),0); LastLow:=LastValue(LowestSinceBars(1,StartOfMonth,LOW)); DaysPassed:=BarsSince(StartOfMonth); LastDay:=LastValue(DaysPassed); DaysLeftInMonth:=If(MonthsRemaining>0, LastValue(ValueWhen(LastValue(MonthsRemaining+PREV-PREV), Endofmonth,DaysPassed)),LastDay)-DaysPassed; currenthigh:=If(MonthsRemaining>0, LastValue(ValueWhen(LastValue(MonthsRemaining+PREV-PREV), EndOfMonth,HighDaysAgo)),LastHigh); currentLow:=If(MonthsRemaining>0, LastValue(ValueWhen(LastValue(MonthsRemaining+PREV-PREV), EndOfMonth,LowDaysAgo)),LastLow); HighDay:=If(DaysLeftInMonth=Currenthigh,1,0); LowDay:=If(DaysLeftInMonth=CurrentLow,-1,0); HighDay; LowDay; work well. Do you have opinion for that? George K.

Dear Jose, I received your Message. I appreciate your answer. Now, i understand! The Formula is Valid without the --->Start---> and <---End<--- George K.

Jose, Well I did like you said -I had a few more beers,-but it didnt work it all looked like a different language by then-lol....I will try again today...I see that my plots work outbut with the new highs and lows .... ... I take it that this indicator would only plot previous months high low not the current month because technically the current month high low wont be know until the end of the month..,or is the everchanging current month also required?

This competition is just pointing to the fact that MSFL is mainly a collection of function calls and routines, lacking 2 or more basic constructs: Loops and Indexed Arrays. Not to mention reliable recursive references instead of PREV. It's ridiculous - in my opinion - to be forced to use constructs like "+PREV-PREV" to achieve the right result. (I am not very clear yet about how this construct works and when it should be used - some comments from experts will be appreciated) The competition target is just so easy to achieve using a simple conditional loop search after the Highest High was identified for each Month. I was told there is a developers group that is working to bring a new life into the MFSL (suggestions@equis.com) and the new features will include loops, indexed arrays and other constructs that are supposed to be part of any decent formula language. Forgive my lack of enthusiasm, but years passed and Equis haven't implemented yet a basic trading tool feature that is to support Intraday Time Frames for 2,4 and 8 hrs. I hope to hear some good news next year. Guara

The 2nd of eight lines of code has now been posted. Watch for the 3rd hint this coming Sunday 18th Dec! jose '-)

Johnl, I have a feeling that you and I are on very different planets. I've really got no idea why you keep mentioning the LastValue function. jose '-)

Congratulations to Wabbit for his lateral-thinking solution! Wabbit has chosen the excellent PremiumData package (valued at between US$290 & $440) for his prize. Wabbit's solution will be released when we have our final winner. We are now looking for our third & final winner who can code the month's High/Low signals without any PREV functions. The 3rd & 4th of eight lines of code have now been posted here. Watch for the crucial 5th hint this coming Thursday 22nd Dec! jose '-)

Thanks G.... Where's your entry? wabbit :D

Jose, I have a question.If you can't answer it because of the answer will give away the competition then I'll just wait till after or maybe I'll understand it when the next line of code is given on the 22nd. My question is :why do you need to identify even and odd months in this indicator? Thanks in advance.
