I'm using the expert advisor to plot a symbol when Bollinger Bandwidth is at it's lowest value for the past 250 days. the formula is: LLV(Fml("BBTK - BandWidth"),250). the problem is that it plots a symbol almost everyday. the pic "LLV_Bandwidth" in the album Expert Advisor Bandwidth shows this.
The bandwidth indicator is plotted on the chart too and it's obvious that it isn't at its lowest value as frequently as the symbol gets plotted.
I've looked at all the lowest functions I can find and none seem better suited for the task than LLV.
I assume this is any easy fix, but I'm stumped. Thank you, jg

LLV returns a value, the Lowest Low Value of BBTK - BandWidth. It is not a True/False aka Conditional statement. The reason it triggers the expert symbols is because any non-zero value counts as a "signal".
You can easily turn your formula into a conditional statement, such as:
Fml("BBTK - BandWidth") = LLV(Fml("BBTK - BandWidth"),250)
