Hello,

I'm trying to set up alerts ( triangle up/down) but I'm having the following issues. the subgraph is showing NaN and when I do and the chart is getting compressed. my formula is =IF(E3>Y4, 1, IF(E3<Z4, 0, " ")).

A space is not a valid number. Your formula does not make any sense, as you are doing an initial test, but in your second test you are giving a value of "0" if true, but then nothing if not true.

Sierra Chart (and most programs) use a value of 1 (or non-zero) for True and a value of 0 for False.

We are not certain what exactly you are wanting to do with the formula you are using.

Also, if you want a triangle at a specific level, then you need to return the level at which you want the triangle. A zero value means do not display. Since you are in a spreadsheet, you can reference the Open/High/Low/Close of a candle for the result. For instance, you can have the following:
=IF(E3>Y4, ID0.SG2@3, IF(E3<Z4, ID0.SG3@3, 0))

Where ID0.SG2 is the High of the bar and ID0.SG3 is the Low of the bar. The @3 signifies to return the value at row 3 of the spreadsheet.
