Code Help to Adjust Hourly H / L Indicator from Ecosystem

[MattD888]

The following code is from the open source indicator on the ecosystem: https://ninjatraderecosystem.com/use...urly-high-low/

I'm trying to gauge how easy it would be to adjust this a (4) hour timeframe. ie: capturing the high and low of each 4 hour period instead of 1 hour.

Would this be a quick change using the code below... or much more complex than just changing a few things...?

Any help or guidance would be great!

CODE BLOCK:

/// <summary>
/// Dynamically plots the highest and lowest of the current hour.//
/// </summary>
public class HourlyHL : Indicator
{
private int startOfHourBarIndex = -1;
private int currentHour = -1;

protected override void OnStateChange()
{
if (State == State.SetDefaults)
{
Description = "Plots the highest and lowest bars for each hour.";
Name = "Hourly High Low";
IsAutoScale = false;
DrawOnPricePanel = false;
IsOverlay = true;
IsSuspendedWhileInactive = true;

// AddPlot for Hourly High
AddPlot(new Stroke(Brushes.SpringGreen, 2), PlotStyle.Square, "Hourly High");
// AddPlot for Hourly Low
AddPlot(new Stroke(Brushes.OrangeRed, 2), PlotStyle.Square, "Hourly Low");
}
}


protected override void OnBarUpdate()
{
DateTime hourBeginning = Time[0].AddMinutes(-1 * Time[0].Minute).AddSeconds(-1 * Time[0].Second);
int hour = hourBeginning.Hour;

if (hour != currentHour)
{
// Start of a new hour, reset startOfHourBarIndex
currentHour = hour;
startOfHourBarIndex = CurrentBar;
}

// Calculate how many bars ago the current hour started
int hourBeginBarsAgo = CurrentBar - startOfHourBarIndex;

if (hourBeginBarsAgo >= 0)
{
double highestHigh = MAX(High, hourBeginBarsAgo + 1)[0];
double lowestLow = MIN(Low, hourBeginBarsAgo + 1)[0];

for (int index = 0; index <= hourBeginBarsAgo; index++)
{
Values[0][index] = highestHigh;
Values[1][index] = lowestLow;
}
}
}
}

}

Hello MattD888,

There would need to be some changes in the logic that calculates the hourBeginning, hour, currentHour, and startOfHourBarIndex variables.

The current logic removes the minutes and seconds from the current bars time. If the hour of this does not equal the last hour value saved to currentHour, then currentHour is updated to the start of the hour for this minute bar. (Meaning the hour of the current minute is different than the last bar that updated)

Likely your logic would need to compare the hour to be greater than or equal to currentHour plus 4 hours.

The level of difficulty would depend on your experience with C# development. With understanding of basic programming concepts and debugging the difficulty would be low.
