Retrieving high() & low() values from different intervals

[waynecd]

Hi,

In this efs I’d like to select the symbol and interval so that it plots the “high(0), low(0), high(-1), low(-1)” on a chart. The issue is that I get null values when I add the “capability” to select a different symbol and interval than that displayed on the chart. In other words, I’d like to display say, above values from a 3 min chart onto a 55T chart.

The attached efs is my original modification using the charts own symbol and interval and it works fine. The following code returns the null values.

Any help is greatly appreciated.

Got it.

I needed to use eval() for:
vIntHigh = high(sym(eval(xSymbol)));
vIntLow = low(sym(eval(xSymbol)));


The code is attached.
