Getting Prior Day Close And Today's Open

[jerrod.davenport]

I'm having a lot of trouble trying to figure this out. Maybe I'm thinking about this the wrong way?

I got the previous day close by adding another data series:

AddDataSeries(BarsPeriodType.Day, 1);

When I output

protected override void OnBarUpdate()
{
if (BarsInProgress == 0)
return;​

Closes[1][0];

When i run the strategy, I get the close from 3 days ago first. Then when the it runs again, I get the 2nd day. And the third time it runs, I get 1 day ago (which is what I'm looking for).
Why doesn't it get the previous day the first time?

I also do not know how to get the current day's open (not pre-market). I thought I could use the same day data series, but this is not working.
Any ideas?

Regarding getting current day's RTH open, assuming you are using an ETH data series - one approach is to get Open[0] when Time[0] is the market's open time (i.e. 9:30am EST) OR you'll need to add an additional RTH data series.

private double rthOpen = 0;  // Variable to store RTH open

protected override void OnBarUpdate()
{
    // Ensure this logic only runs for the primary minute bar data series
    if (BarsInProgress != 0) return;  // Check if the current data series triggering OnBarUpdate is the primary series

    // Check if there is enough data
    if (CurrentBar < 1) return;

    // Define RTH start time
    TimeSpan rthStartTime = new TimeSpan(9, 30, 0);  // 9:30 AM ET

    // Check if the bar's time matches RTH start time (assuming 1-minute bars for the primary series)
    if (ToTime(Time[0]) == ToTime(rthStartTime))
    {
        // Store the open of the bar which corresponds to the RTH open
        rthOpen = Open[0];
        // Print the RTH open; useful for debugging or real-time monitoring
        Print("Today's RTH open was: " + rthOpen);
    }
}

Hello,

Thank you for your post.

You can use the PriorDayOHLC and CurrentDayOHL indicators to get these values.
