How to display levels on an Indicator?

Hi FireMyst,

What do you expect the code to do?  UpwardCount is always 0.

I expect cTrader to show the levels 0, 1, 2 as per the Levels specification at the top of the code:

[Levels(2, 1, 0)]

regardless of what the output values would be.

Just like some indicators would have levels -2, -1, 0, 1, 2, but if the indicator runs and never goes below zero, the levels -1 and -2 are still shown.

Hi FireMyst,

The levels will appear when your indicator starts getting more values. At the moment it is zoomed at 0. e.g.

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

namespace cAlgo
{
    [Levels(2, 1, 0)]
    [Indicator(IsOverlay = false, TimeZone = TimeZones.UTC, AccessRights = AccessRights.None)]
    public class ConditionsOfEntry : Indicator
    {
        [Output("UpwardSell", LineStyle = LineStyle.Solid, PlotType = PlotType.Points, LineColor = "Red")]
        public IndicatorDataSeries UpwardSell { get; set; }
        [Output("UpwardNeutral", LineStyle = LineStyle.Solid, PlotType = PlotType.Points, LineColor = "Yellow")]
        public IndicatorDataSeries UpwardNeutral { get; set; }
        [Output("UpwardBuy", LineStyle = LineStyle.Solid, PlotType = PlotType.Points, LineColor = "Lime")]
        public IndicatorDataSeries UpwardBuy { get; set; }

        public int UpwardCount { get; set; }

        private const int UpwardMax = 5;

        public override void Calculate(int index)
        {
            //if (UpwardCount >= UpwardMax)
            UpwardBuy[index] = index % 10;
            //else if (UpwardCount > Math.Round(UpwardMax / 2.0, MidpointRounding.AwayFromZero))
            //    UpwardNeutral[index] = UpwardCount;
            //else
            //    UpwardSell[index] = UpwardCount;
        }

    }
}

        }

    }

I obviously found that a bit confusing because when I specify levels, I'd expect to see them there when the chart loads.

Might be worth considering updating the API documentation so others aren't caught out by it,but I'll leave that decision with your team.

Thank you.
