Multi time-frame chart labels on 5 min chart

I tested this as thoroughly as I could and you are correct. I could not find a cause. I did find that it’s only the thirty min time frame causing the error. You can substitute “AggregationPeriod.FIFTEEN_MIN” in place of “AggregationPeriod.THIRTY_MIN” and the hourly label will work.

When chart studies do not plot, be sure to check the upper left hand corner for an error message. See attached screenshots for detail. There is an exclamation mark inside a circle. Click that whenever you see to get a list of problems generated for that chart.

In this case it tells us that “Two different secondary periods cannot be used within a signal variable”. However it is perfectly clear you code does NOT break this rule. The platform is misinterpreting things.

I recommend you submit this to TDA support for analysis.

In your code there are some minor issues with style. You have gotten the capitalization rules backwards. User defined inputs and variables should always begin with lowercase. System constants and methods should always begin with a capital letter. The data objects for chart data always begin with a lowercase letter (open, high, low, close, volume). Whenever you are not sure just look at the examples provided by Thinkorswim in their language reference: http://tlc.thinkorswim.com/center/reference/thinkScript/Constants/AggregationPeriod/AggregationPeriod-FIFTEEN-MIN.html

Here is a cleaned up version of your code that corrects all of these style issues:


input period5 = AggregationPeriod.FIVE_MIN;
input period15 = AggregationPeriod.FIFTEEN_MIN;
input period30 = AggregationPeriod.THIRTY_MIN;
input periodHour = AggregationPeriod.HOUR;
#5 min chart
def greenCandle5 = close(period = period5) > open(period = period5);
AddLabel(yes, “X5”, if greenCandle5 then color.CYAN else color.YELLOW);
AddLabel(yes, “||”, color.VIOLET);
#15 min chart
def greenCandle15 = close(period = period15) > open(period = period15);
AddLabel(yes, “X15”, if greenCandle15 then color.CYAN else color.YELLOW);
AddLabel(yes, “||”, color.VIOLET);
#30 min chart
def greenCandle30 = close(period = period30) > open(period = period30);
AddLabel(yes, “X30”, if greenCandle30 then color.CYAN else color.YELLOW);
AddLabel(yes, “||”, color.VIOLET);
#1 Hour chart
def greenCandlehour = close(period = periodHour) > open(period = periodHour);
AddLabel(yes, “XHour”, if greenCandlehour then color.CYAN else color.YELLOW);
AddLabel(yes, “||”, color.VIOLET);

In closing I will leave you with a few more tips. Always place your inputs at the very top of your code, grouped together as you see here. When testing if a variable is true, there is no need to use “= 1”. Notice that I only need to say: if greenCandle5and I did not need to say: if greenCandle5 = 1

Those changes don’t make the code work. But it makes it easier to read and maintain. It’s something in the platforum that is broken. The code should work fine.

Good luck!
