high() and low() unexpected null returns

[Dave180]

Hi
Someone please remind me what I'm doing wrong, I'm trying to step back through the high() and low() values of previous bars. It works for the previous candle (-1) but not for a general negative number. [Edit: It also works when processing historic bars, but fails when we get to the current bar.]

I think

nVal = high(nCandle); 

should access the high values for the symbol and interval of the current chart and return a valid value for any nCandle (a negative) which, as I don't do this until we get to the current bar, is not a value greater in magnitude than the number of bars in the chart. I get null as the return, eSig 10.0.

I can't work it out.

Thanks

As far as I can see at my end calling any previous bar using the bar index [as long as it does not exceed the oldest bar index] while on the most recent bar appears to be returning the correct value (see enclosed screenshots).
You may want to post a more detailed example so as to try to identify what the issue may be

Alexis, my apologies, I never saw your response (I think the advisory emails sometimes don't arrive), and meanwhile I think I hard-coded an array and loop to get around the problem. I'll look again shortly.
