Hi Tengu,

See an example below

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

namespace cAlgo
{
    [Cloud("Fast MA", "Slow MA", FirstColor = "Aqua", Opacity = 0.5, SecondColor = "Red")]
    [Indicator(IsOverlay = true, TimeZone = TimeZones.UTC, AccessRights = AccessRights.None)]
    public class CloudExample : Indicator
    {
        [Parameter("Fast MA Period", DefaultValue = 21)]
        public int FastMaPeriod { get; set; }

        [Parameter("Slow MA Period", DefaultValue = 50)]
        public int SlowMaPeriod { get; set; }

        [Output("Fast MA", LineColor = "#FF6666")]
        public IndicatorDataSeries FastMaResult { get; set; }

        [Output("Slow MA", LineColor = "#0071C1")]
        public IndicatorDataSeries SlowMaResult { get; set; }

        SimpleMovingAverage FastMa;
        SimpleMovingAverage SlowMa;


        protected override void Initialize()
        {
            FastMa = Indicators.SimpleMovingAverage(Bars.ClosePrices, FastMaPeriod);
            SlowMa = Indicators.SimpleMovingAverage(Bars.ClosePrices, SlowMaPeriod);
        }

        public override void Calculate(int index)
        {
            FastMaResult[index] = FastMa.Result[index];
            SlowMaResult[index] = SlowMa.Result[index];
        }
    }
}

HI @Panagiotis:

A few questions from this:

1) how do we draw clouds between multiple lines within an indicator? For example, imagine an indicator on a price chart that draws horizontal lines at 1, 2, 3, and 4. All 4 lines are different colors. I want one cloud drawn between lines 1 & 2; another cloud drawn between lines 2 & 3; a third cloud drawn between lines 3 & 4. Is this possible?

2) If the above is possible, how can we programmatically change the colors of the clouds or give users the ability to select the colors they want the clouds to be?

Thank you.

Hi firemyst,

1) Just add more Cloud attributes e.g. 

    [Cloud("Fast MA", "Slow MA", FirstColor = "Aqua", Opacity = 0.5, SecondColor = "Red")]
    [Cloud("Slow MA", "Super Slow MA", FirstColor = "Green", Opacity = 0.5, SecondColor = "Blue")]
    [Indicator(IsOverlay = true, TimeZone = TimeZones.UTC, AccessRights = AccessRights.None)]

2) There is no such option at the moment.
