Indicator example: Multi-timeframe moving average

In this example, we output moving averages with the same period for different timeframes on a single chart:

Source code:

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

namespace cAlgo.Indicators
{
    [Indicator(IsOverlay = true, TimeZone = TimeZones.UTC)]
    public class MultiTF_MA : Indicator
    {
        [Parameter(DefaultValue = 50)]
        public int Period { get; set; }

        [Output("MA", Color = Colors.Yellow)]
        public IndicatorDataSeries MA { get; set; }

        [Output("MA5", Color = Colors.Orange)]
        public IndicatorDataSeries MA5 { get; set; }

        public IndicatorDataSeries MA10 { get; set; }

        private MarketSeries series5;
        private MarketSeries series10;

        private MovingAverage ma;
        private MovingAverage ma5;
        private MovingAverage ma10;

        {
            series5 = MarketData.GetSeries(TimeFrame.Minute5);
            series10 = MarketData.GetSeries(TimeFrame.Minute10);

            ma = Indicators.MovingAverage(MarketSeries.Close, Period, MovingAverageType.Triangular);
            ma5 = Indicators.MovingAverage(series5.Close, Period, MovingAverageType.Triangular);
            ma10 = Indicators.MovingAverage(series10.Close, Period, MovingAverageType.Triangular);
        }

        public override void Calculate(int index)
        {
            MA[index] = ma.Result[index];

            var index5 = GetIndexByDate(series5, MarketSeries.OpenTime[index]);
            if (index5 != -1)
                MA5[index] = ma5.Result[index5];

            var index10 = GetIndexByDate(series10, MarketSeries.OpenTime[index]);

                MA10[index] = ma10.Result[index10];
        }


        private int GetIndexByDate(MarketSeries series, DateTime time)
        {
            for (int i = series.Close.Count - 1; i > 0; i--)
            {
                if (time == series.OpenTime[i])
                    return i;
            }
            return -1;
        }
    }

Multi-timeframe robot

This is the RSI robot. It uses a daily Average True Range value as a filter, i.e. it does not trade if the ATR value is greater than the specified parameter value:

using System;
using System.Linq;
using cAlgo.API;
using cAlgo.API.Indicators;
using cAlgo.API.Requests;
using cAlgo.Indicators;

namespace cAlgo.Robots

    [Robot(TimeZone = TimeZones.UTC)]
    public class SampleRSIRobot : Robot
    {
        [Parameter("Max ATR Value", DefaultValue = 0.01)]
        public double MaxAtrValue { get; set; }

        private RelativeStrengthIndex rsi;
        private AverageTrueRange atr;

        protected override void OnStart()
        {
            rsi = Indicators.RelativeStrengthIndex(MarketSeries.Close, 14);

            var dailySeries = MarketData.GetSeries(TimeFrame.Daily);
            atr = Indicators.AverageTrueRange(dailySeries, 20, MovingAverageType.Simple);
        }

        protected override void OnTick()
        {
            if (Trade.IsExecuting)
                return;

            // Do nothing if daily ATR value > Max allowed value
            if (atr.Result.LastValue > MaxAtrValue)
                return;

            if (rsi.Result.LastValue < 30)
            {
                OpenPosition(TradeType.Buy);
            }
            else if (rsi.Result.LastValue > 70)
            {
                OpenPosition(TradeType.Sell);
            }
        }

        private void OpenPosition(TradeType tradeType)
        {
            foreach (var position in Account.Positions)
            {
                if (position.Label == "SampleRSIRobot" && position.TradeType != tradeType)
                {
                    Trade.Close(position);
                }
            }

            bool hasNeededPosition = Account.Positions.Any(position => position.Label == "SampleRSIRobot" && position.TradeType == tradeType);
            if (!hasNeededPosition)
            {
                var request = new MarketOrderRequest(tradeType, 10000) 
                {
                    Label = "SampleRSIRobot",
                    StopLossPips = 20
                };
                Trade.Send(request);
            }
        }

RE:

Thank you for this upgrade which seems to be something I am looking for.

Is there any description of how to use these series in the context of Calculate method?

I know Calculate is called with an index parameter.

How that index relates to instantiated m10 or m1 for that matter ?

How often Calculate method is called by who and when and what is index relative to ?

(I know it is called at some irregular intervals in real time and any time a graph point is evaluated,

but I cannot correlate it to the last "10 minute" or "one minute" bar.)

My question may seem naive for you guys who know this software inside out, but this kind of

questions arise for anyone new to cAlgo. We badly need some glue logic described somewhere.

Descriptions are minimalistic. A simple question like Print method nowhere describes where

does the print go to. So far I know it goes o a log file, but could not find the log anywhere.

I find cAlgo exeptionally cool tool but I am having trouble to get started due to insufficient

description. C# is not an issue here but general concept of all classes and objects and how they tie together.

Of course I will slowly build the picture but it will be a long process.

Cheers

We added new functionality to cAlgo - the ability for robots and indicators to retrieve OHLCV data for multiple timeframes. This can be done using the MarketData.GetSeries method:

MarketSeries m5series = MarketData.GetSeries(TimeFrame.Minute5);

We recommend to call the GetSeries method in the Robot.OnStart() or the Indicator.Initialize() methods.

When the series for a specified timeframe is received, you can access the series values or build an indicator based on that series:

private MarketSeries m10;
private MovingAverage ma;

protected override void OnStart()
{
    m10 = MarketData.GetSeries(TimeFrame.Minute10);
    ma = Indicators.SimpleMovingAverage(m10.High, 14);
}

The new version of our Demo cTrader and cAlgo is released and can be downloaded from www.spotware.com

Backtesting of Multi-timeframe robots in not supported yet. We will support it in the next version.

(I know it is called at some irregular intervals in real time and any time a graph point is evaluated,

but I cannot correlate it to the last "10 minute" or "one minute" bar.)

 

The Calculate method is called on each historical bar in the series the instance is attached to (i.e. EURUSD H1). Once it reaches real time, it is called on each incoming tick of that symbol, as well as on each incoming tick of any other symbols for which the series are retrieved.

The "index" that is the parameter to the Calculate method, is the index of the series that the instance is attached to. The series of other timeframes / symbols have different indexes. So, to get the index of a specific series you would need to use a method such as GetIndexByDate (Described in the example above: Multi-timeframe moving average)

         private int GetIndexByDate(MarketSeries series, DateTime time)
        {
            for (int i = series.Close.Count - 1; i > 0; i--)
            {
                if (time == series.OpenTime[i])
                    return i;
            }
            return -1;
        }
    }
}

Descriptions are minimalistic. A simple question like Print method nowhere describes where

does the print go to. So far I know it goes o a log file, but could not find the log anywhere.

I find cAlgo exeptionally cool tool but I am having trouble to get started due to insufficient

description. C# is not an issue here but general concept of all classes and objects and how they tie together.

 The Print method prints to the Log within the platform, not a log file. It is the last tab in the bottom panel of the chart view.

We are preparing a manual for cAlgo with more detailed descriptions of all the main classes in the API.

I am trying to use this feature to create Heikin-Ashi indicator with custom timeframe as below. The value of haClose in the HeikinAshiClose series looks correct but I am always getting NaN for haOpen. I am not sure if something like below is supported?

RE: Indicator example: Multi-timeframe moving average

Without plotting the actual moving average lines, how would I just output the numerical value of how far the 100 DAY moving average is from the current price on a one HOUR price chart, plotting just the numerical value in the top left corner of the a one hour price chart, i.e.,

(100 DAY moving average value) - (Current price on a one HOUR chart). With the numerical value output in the top left corner of the one hour chart. When I'm looking at shorter time frame charts like an hour or 15 minute charts, I want to know how far the close is from DAILY moving averages. The code below really only works if you want to know the MAs of shorter timeframes than the chart that you are viewing. I want to know the opposite, i.e, show longer timeframe MAs on shorter timeframe charts.

In this example, we output moving averages with the same period for different timeframes on a single chart:

        [Output("MA10", Color = Colors.Red)]
        public IndicatorDataSeries MA10 { get; set; }

        private MarketSeries series5;
        private MarketSeries series10;

        private MovingAverage ma;

            series10 = MarketData.GetSeries(TimeFrame.Minute10);

            ma = Indicators.MovingAverage(MarketSeries.Close, Period, MovingAverageType.Triangular);
            ma5 = Indicators.MovingAverage(series5.Close, Period, MovingAverageType.Triangular);
            ma10 = Indicators.MovingAverage(series10.Close, Period, MovingAverageType.Triangular);
        }

        public override void Calculate(int index)
        {
            MA[index] = ma.Result[index];

            var index5 = GetIndexByDate(series5, MarketSeries.OpenTime[index]);
            if (index5 != -1)
                MA5[index] = ma5.Result[index5];

            var index10 = GetIndexByDate(series10, MarketSeries.OpenTime[index]);
            if (index10 != -1)
                MA10[index] = ma10.Result[index10];
        }

            {
                if (time == series.OpenTime[i])
                    return i;
            }

        }
    }

Thats a great feature. I love multiple EMA in with different time frame.

MarketData.GetSeries doesnt work properly!!!

For example, If indicator is on Hour1 Timeframe and I want to get DataSeries from Minute1 Timeframe, it only get truncated Minute1 DataSeries.

DataSeries.Close.Count = 6000

M1DataSeries.Close.Count = 9000, but it should be at least 6 000 x 60 = 360 000!

And when you scroll to the beginning DataSeries.Close is updated, but M1DataSeries.Close is the same = 9000.

Please, fix it!

We added new functionality to cAlgo - the ability for robots and indicators to retrieve OHLCV data for multiple timeframes. This can be done using the MarketData.GetSeries method:

Dear PanagiotisCharalampous thanks a lot for the reply. Greatly appreciated...

I'm traying to design a GannHighLow Multi-Timeframe indicator useful to build up a multi-frame cBot afterwards, and with no success at the moment.

I have tried a referencing and also a direct re-coding of the provided by cTrader samples. Still no success. Both options work well on the chats with the same time scale, but are showing some nonsense lines on the chats with longer or shorter timeframes. It looks like the problem is in re-indexing of series for the Custom Timeframe. The HiLo is using the [index - 1] value, which might be deteriorating the graph, but my knowledge is too limited to sort it out. It would be great, if you could give some advise... Thanks in advance.

One of the codes, which I'm trying to finish, is here:

Hi alexnikon,

I am not sure what is the indicator supposed to do but your indexing is definitely wrong. See below how to get the correct indices for your indicators

            double smaHigh = _smaHigh.Result[_bars.OpenTimes.GetIndexByTime(Bars.OpenTimes[index]) - 0];
            double smaHighPrev = _smaHigh.Result[_bars.OpenTimes.GetIndexByTime(Bars.OpenTimes[index]) - 1];
            double smaLow = _smaLow.Result[_bars.OpenTimes.GetIndexByTime(Bars.OpenTimes[index]) - 0];
            double smaLowPrev = _smaLow.Result[_bars.OpenTimes.GetIndexByTime(Bars.OpenTimes[index]) - 1];

Let me know if this helps

Thanks a lot !! It looks better. It draws more sensible line if the Custom timescale is shorter than the carrier chart, but it is still wrong if it is longer. F.e. on the base H1 chart, the Custom frame M10 looks nearly properly (even not sure), but the D1 is wrong...

Note: I want eventually use the GannHiLo for a cBot to trigger when Close price crosses the HiLo on the triple screen view (by Elder). It seams to be working as a kind of dynamic support line...

Dear PanagiotisCharalampous. Thank you very much again. Sorry, the Gann-High-Low indicator isn't very popular. It is based on moving averages of High and Low prices of the series. It shows only one of them which is below the trend - would it be  the average of Highs or Lows depending of the trend direction. The line sharply swaps the side around the trend when the Close price penetrates the actual high or low price average line in the opposite movement and the trend changes direction (pict.1).

Not sure whether my explanation is clear, but hope the pictures can help. I sorry for asking so much attention... Thanks in advance...

Historical Data is wrong

Hi,

Why is the historical data wrong when using a different time frame and retrieving the index by GetIndexByTime? How could the indicator already know the high and low value (sma period = 1) at 9 pm of the previous day (see 1. screen shot)? If I a reduce dataIndex by 1 it is correct but is this how you should use GetIndexByTime? If you leave the indicator on the chart for a while, the values calculated while the chart was open behave different then the ones calculated from historical data during initializaiton of the indicator (see 2. screen shot). The last 3 bars all have different low values (red line) but all others (calculated during init) alway have 2 same values (this was done on 1m chart with tf parameter set to 2m).

Kind regards

Hi cW22Trader,

How could the indicator already know the high and low value (sma period = 1) at 9 pm of the previous day (see 1. screen shot)?

Because you are retrieving data for historical bars that have already been closed. All the bars you retrieve are closed bars. When you get data using GetIndexByTime(), you don't get the bar as it was at the specific point of time, but the completed bar where the requested time falls in.

If you are looking to find the bar state at the specific point of time, then this functionality is not offered by the API. You will need to develop something yourself.

I understand that the API does not offer intermediat data of a past bar of a different time frame. Unfortunately, this makes it impossible to run in backtest since the data form a different time frame is futur data.

E.g. on a 1h chart with an indicator using data form the 4h time frame and simply displays the OHLC data as static text on chart, every time a new 4h bar starts it already shows the future high and low of the next 4h in visual backtesting. I would expect that the last bar of the 4h time frame "builds up" during the next 4h in visual backtesting and only stores the open, high, low and close of that bar once it is complete just like it does in real-time mode.

Kind regards

Refer price/indicator values on different Range chart

Hi Ctrader team,

Is it possible to refer to Open/Close/High/Low values & Indicator results from a different Range Bar chart?

Like running Ra100 Chart while getting values from Ra500 for example, just like referring values in a higher TF?

If not yet possible; any plans to implement this already?

Thanks in advance!

I think this is possible at least with Renko. This should be the same with Range bars.

But be carefull when using OHLC data of "higher" or larger TF. On historical data of e.g. on a chart it will use future data of the higher TF. E.g. a Ra100 bar just closed and your indicator algo gets triggered and you also get the data from the Ra500 bar using this API "Ra500bar.OpenTimes.GetIndexByTime(Ra100bar.OpenTimes[index])". The Ra500 bar may not be closed yet but since on historical data you only have access to completed OHLC data, you would use future data of that Ra500 bar which produces unrealistic results.

@cTrader Team: please correct me if I'm wrong...

Kind regards

Thanks! Got me further. I can now get the values from a custom Indicator; but I can't seem to refer to a different RangeBar chart with the standard build in Indicators (for e.g. Supertrend).

Could you help me out a bit here?

So, the DSS values I get back correct; ST values are from the TF the Bot is running on; so that is also fine.

But When I add Ra500 to the ST500 line, like below, it fails and mentioned an overload as only wants to see 2 arguments.

ST500 = Indicators.Supertrend(Ra500, 10, 3.0);

(If I change the indicator to for example a Moving Average like: ST500 = Indicators.MovingAverage(Ra500.ClosePrices, 10, MovingAverageType.Exponential);, no error messages displayed. So seems issue with Supertrend, or I misconfigure it..)

I also got it working if I download the custom Supertrend indicator that can be found in the Algorithms section, but I rather use the standard one located in cTrader.

Ps. I add the code to OnStart, so I can test this in the weekend, as we cannot Backtest RangeBar data..

Thanks in advance!

Hi,

The built-in super trend indicator doesn't support multiple time frames, you can only use if for the current time frame.

If you want to use super trend on another time frame then you have to develop a custom version by yourself, you can find some examples on site if you search.

TimeFrame parameters

Another feature that has been introduced, is parameters of TimeFrame type that can be used in multi-timeframe robots and indicators:

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

namespace cAlgo.Robots
{
    [Robot(TimeZone = TimeZones.UTC)]
    public class MultiTimeFrameBot : Robot
    {
        [Parameter("Another Timeframe", DefaultValue = "Minute10")]
        public TimeFrame AnotherTimeFrame { get; set; }

        protected override void OnStart()
        {
            var anotherSeries = MarketData.GetSeries(AnotherTimeFrame);

            Print("My TimeFrame: {0}, Last high: {1}, Last Low: {2}", TimeFrame, MarketSeries.High.LastValue, MarketSeries.Low.LastValue);
            Print("Another TimeFrame: {0}, Last high: {1}, Last Low: {2}", AnotherTimeFrame, anotherSeries.High.LastValue, anotherSeries.Low.LastValue);
        }
    }
}

As a result we have a robot like this:

I have modified the indicator to just display daily 50/100/200 averages on the chart. 

Please have alook. I am very novice at this. 

I do wanted to ask, is it possible to disable this overlay value which appear on when mouse hovers over the MA lines?

Here is the full code:

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

namespace cAlgo.Indicators
{
    [Indicator(IsOverlay = true, TimeZone = TimeZones.UTC)]
    public class MultiTF_MA2 : Indicator
    {

        [Output("MA50", Color = Colors.Red)]
        public IndicatorDataSeries MA50 { get; set; }

        [Output("MA100", Color = Colors.Green)]
        public IndicatorDataSeries MA100 { get; set; }

        [Output("MA200", Color = Colors.White)]
        public IndicatorDataSeries MA200 { get; set; }

        private MarketSeries seriesdaily;

        private MovingAverage ma50;
        private MovingAverage ma100;
        private MovingAverage ma200;

        protected override void Initialize()
        {
            seriesdaily = MarketData.GetSeries(TimeFrame.Daily);
            ma50 = Indicators.MovingAverage(seriesdaily.Close, 50, MovingAverageType.Simple);
            ma100 = Indicators.MovingAverage(seriesdaily.Close, 100, MovingAverageType.Simple);
            ma200 = Indicators.MovingAverage(seriesdaily.Close, 200, MovingAverageType.Simple);
        }

        public override void Calculate(int index)
        {

            var index50 = GetIndexByDate(seriesdaily, MarketSeries.OpenTime[index]);
            if (index50 != -1)
                MA50[index] = ma50.Result[index50];

            var index100 = GetIndexByDate(seriesdaily, MarketSeries.OpenTime[index]);
            if (index100 != -1)
                MA100[index] = ma100.Result[index100];

            var index200 = GetIndexByDate(seriesdaily, MarketSeries.OpenTime[index]);

            {
                if (time == series.OpenTime[i])
                    return i;
            }

Hi alexnikon,

I cannot help you further at the moment because I have no idea what is the indicator expected to do. You need to provide more information of what the expected outcome should be and what does the indicator do instead. Screenshots would be helpful.

Dear PanagiotisCharalampous. Thank you very much again. Sorry, the Gann-High-Low indicator isn't very popular. It is based on moving averages of High and Low prices of the series. It shows only one of them which is below the trend - would it be  the average of Highs or Lows depending of the trend direction. The line sharply swaps the side around the trend when the Close price penetrates the actual high or low price average line in the opposite movement and the trend changes direction (pict.1).

Not sure whether my explanation is clear, but hope the pictures can help. I sorry for asking so much attention... Thanks in advance...

Dear Panagiotic

Here you can see what the H1 chart looks like when I use consecutively M5, Daily and H1 (normal) custom frames.

(Sorry for publishing them this way. Can not see how to attach the link from cTrader directly...)

Thank you very much.
