using System.Collections.Generic;

namespace WealthLab
{
    public class MyStrategy : UserStrategyBase
    {
        //display the scale of the chart
        public override void Initialize(BarHistory bars)
        {
			DrawHeaderText("The current scale is: " + bars.Scale.Description);
        }

        public override void Execute(BarHistory bars, int idx)

using System.Collections.Generic;

namespace WealthLab
{
    public class MyStrategy : UserStrategyBase
    {
        //create indicators and other objects here, this is executed prior to the main trading loop
        public override void Initialize(BarHistory bars)
        {
			DrawHeaderText("Bar Scale = " + bars.Scale);
			DrawHeaderText("Bar Interval = " + bars.Scale.Interval);
        }

        public override void Execute(BarHistory bars, int idx)
        {
        }
    }
}
Interval

Represents the time interval for Minute, Second and Tick scales.

Example Code
using WealthLab.Backtest;
using System;
using WealthLab.Core;
using WealthLab.Indicators;
using WealthLab.ChartWPF;
using System.Drawing;
using System.Collections.Generic;

namespace WealthLab
{
    public class MyStrategy : UserStrategyBase
    {
        //create indicators and other objects here, this is executed prior to the main trading loop
        public override void Initialize(BarHistory bars)
        {
			DrawHeaderText("Bar Scale = " + bars.Scale);
			DrawHeaderText("Bar Interval = " + bars.Scale.Interval);
        }

        public override void Execute(BarHistory bars, int idx)
        {
        }
    }
}

using WealthLab.ChartWPF;
using System.Drawing;
using System.Collections.Generic;

namespace WealthLab
{
    public class MyStrategy : UserStrategyBase
    {
        //create indicators and other objects here, this is executed prior to the main trading loop
        public override void Initialize(BarHistory bars)
        {
			if (bars.Scale.IsIntraday)
				DrawHeaderText("Intraday Chart!", WLColor.Red);
        }

        public override void Execute(BarHistory bars, int idx)
        {
        }
    }
}
Static Helpers
public static HistoryScale Daily = new HistoryScale(Frequency.Daily)
public static HistoryScale Weekly = new HistoryScale(Frequency.Weekly)
public static HistoryScale Monthly = new HistoryScale(Frequency.Monthly)
public static HistoryScale Quarterly = new HistoryScale(Frequency.Quarterly)
public static HistoryScale Yearly = new HistoryScale(Frequency.Yearly)
