MaxVisibleBars

While developing an indicator which is using Chart.MaxVisibleBars add an instance.

Switching back to it's source window, the MaxVisibleBars value is changing.

To reproduce, run the code in snippet then toggle between source and instance.

using System;
using cAlgo.API;
using cAlgo.API.Internals;
using cAlgo.API.Indicators;
using cAlgo.Indicators;

namespace cAlgo
{
    [Indicator(IsOverlay = false, TimeZone = TimeZones.UTC, AccessRights = AccessRights.None)]
    public class TestMaxVisibleBars : Indicator
    {

        int prevValue;

        public override void Calculate(int index)
        {
            if (prevValue != 0 && prevValue != Chart.MaxVisibleBars)
                Print("prev=", prevValue, " curr=", Chart.MaxVisibleBars);
            prevValue = Chart.MaxVisibleBars;
        }
    }
}
