Multi Time Frame EMA
22 Oct 2018, 19:10

Hi everybody,

It 's EMA(20) of 1 Hour Period on 5 min chart. Does anybody know why the last segment of EMA is not straight like previous segments? That is the code (it is written like one of indicators of API Guide):

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

namespace cAlgo.Indicators
{
    [Indicator(IsOverlay = true, AutoRescale = false, TimeZone = TimeZones.FLEStandardTime, AccessRights = AccessRights.None)]
    public class MTF_EMA_1H : Indicator
    {
        [Parameter(DefaultValue = 20)]
        public int Period { get; set; }

        [Output("EMA 1H", Color = Colors.OrangeRed)]
        public IndicatorDataSeries EMAH { get; set; }

        private MarketSeries seriesHour;

        private MovingAverage emaH;

        protected override void Initialize()
        {

            seriesHour = MarketData.GetSeries(TimeFrame.Hour);

      emaH = Indicators.MovingAverage(seriesHour.Close, Period, MovingAverageType.Exponential);
        }

        public override void Calculate(int index)
        {

            var indexH = seriesHour.OpenTime.GetIndexByTime(MarketSeries.OpenTime[index]);

            if (indexH != -1)
                EMAH[index] = emaH.Result[indexH];
        }
    }
}

Because the last 1H bar is not closed and the EMA value on it is recalculated with each tick.

The correct value will be the last on the 12th closed bar (60 min / 5 min = 12 bars).

Freeman is right, the longer the timeframe the more jaggered the line will appear in the lower TF's. ie: the weekly would look like a ZigZg Indicator..........

I have added an Oscillating version of a MA MTF Indicator (completely adjustable) which will smooth out the Moving Averages for you.....

If you want to place the chart change the line (8) of code below.

[Indicator(IsOverlay = true, AccessRights = AccessRights.None, TimeZone = TimeZones.UTC)]

Hope this is of some help...... Cheers

Hello

How can I change the code to show me two EMA 20 and 40 on the H4 chart with the D1 timeframe?

Best Regards

To modify Indicator so it overlays the chart (not display as an Oscillator) paste the line of code below (Overlay = true) in the code and recompile.

Line 8 [Indicator(IsOverlay = true, AccessRights = AccessRights.None, TimeZone = TimeZones.UTC)]

Change Timeframe 1 to Daily1, Period TF 1 to 20 | Timeframe 2 to Daily1, Period TF 2 to 40 | Timeframe 3 to Daily1, Period TF 3 to 200 (For reference)

This gives the result you requested........ Zoomed out, Looks terrific for long term position...... Good Luck
