Indicator works on time but not on tick or volume

[ballboy11]

I have been using Visual studio to try find this OnBarUpdate issue. I have a -1 index that is out of range.

It works on minute charts but when I test on non time frame charts I get the error. The error is setting the plot

MyPlot[0] = Bollinger(2, 14).Middle[0]


The system is set to Calculate = Calculate.OnEachTick;

f (BarsInProgress == 1 && CurrentBars[1] > 20 && IsFirstTickOfBar == true)
{

MyPlot[0] = Bollinger(2, 14).Middle[0];


the 2 questions are the following

1. On Currentbar is there a way to make sure you have enough CurrentBars to run?

2. If this is set to Calculate.OnEachTick; do I get my logic at index 1 or index 0 because IsFirstTickOfBar == true;
This plot is just a line.

Hello ballboy11,

Is MyPlot set to return a plot from the Values collection added with AddPlot()?

Can you set other values to this series and print this value?

If you call Print(Bollinger(2, 14).Middle[0]); does this print or error?

This depends on the indexes being used.

If you have a barsAgo value you are planning to use, you can ensure that CurrentBars[0] && CurrentBars[1] are both greater than that value.

if (CurrentBars[0] > myBarsAgoValue && CurrentBars[1] > myBarsAgoValue)
{
Print(Time[myBarsAgoValue]);
}

When in real-time with Calculate.OnEachTick, barsAgo 0 will be the currently open building bar. barsAgo 1 will be the most recent fully closed bar.
If you set a value any time while that bar is open that will be the value used, even if this is on the first tick.
