Storing Current Values to use as previous values

[AdeptistJune]

Hello, I was finally able to create RTHOHL values that plot until the next RTH trading session. My question is how do I now store those the current values into previous values using the current script?

Thanks,


protected override void OnBarUpdate()
{

if (!Bars.BarsType.IsIntraday) return;

lastDate = currentDate;
currentDate = sessionIterator.GetTradingDay(Time[0]);


if (Time[0] >= sessionIterator.ActualSessionBegin && Time[0] <= sessionIterator.ActualSessionEnd || Bars.IsFirstBarOfSession)
//if (Bars.IsFirstBarOfSession)
//if (lastDate != currentDate || currentOpen == double.MinValue)
{
currentOpen = Open[0];
currentHigh = High[0];
currentLow = Low[0];

//Print(Time[0] + "|" + "lastDate" + lastDate + "|" + "currentDate" + currentDate);
}

currentHigh = Math.Max(currentHigh, High[0]);
currentLow = Math.Min(currentLow, Low[0]);

//Print(String.Format("Time[0]: {0} lastDate: {1} currentDate: {2}",
//Time[0], lastDate, currentDate));

if (ShowOpen)
CurrentOpen[0] = currentOpen;

if (ShowHigh)
CurrentHigh[0] = currentHigh;

if (ShowLow)
CurrentLow[0] = currentLow;

if (BarsInProgress != 0)
return;

if (CurrentBars[0] < 1)
return;

if (Times[0][0].TimeOfDay >= new TimeSpan(17, 00, 00) || Times[0][0].TimeOfDay <= new TimeSpan(08,30, 00))
{
CurrentOpen[0] = CurrentOpen[1];
CurrentHigh[0] = CurrentHigh[1];
CurrentLow[0] = CurrentLow[1];
}
Print(String.Format("Time[0]: {0} | CurrentOpen[0]: {1} | CurrentHigh[0]: {2} | CurrentLow[0]: {3}",
Time[0], CurrentOpen[0], CurrentHigh[0], CurrentLow[0] ));
}

Hi AdeptistJune, thanks for posting.

We will not be able to create new code for you. Could you be more specific with your question?

Good morning Chris,

No, I don't want you to generate new code for me. I just need information on how to properly store my current days plot value and reference those values going forward.

Hi, thanks for your reply.

There are several ways to store information. In NinjaTrader we can set up Series<T> objects that can hold a data point of any type for each bar on the chart:

Other in-memory storage options:

If you need to store something between sessions when the computer is turned off, you can store values to a .txt file. We have an example here:
