Hi silvio,

Is there a reason you do not use the built in Renko Charts?

Hi Panagiotis,

I wasn't aware that API for built in Renko is available. I was searching here https://ctrader.com/api/reference/indicators.

Can you advise where to find it?

Thanks

Silvio

Hi silvio,

See screenshot below

You can change the code as below and run the cBot on a Renko chart.

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

namespace cAlgo.Robots
{
    [Robot(TimeZone = TimeZones.UTC, AccessRights = AccessRights.None)]
    public class NewcBot : Robot
    {
        protected override void OnStart()
        {
            for (var i = 0; i < 10; i++)
            {
                Print("ON-ST-(renko O;C) [", i, "]: ", MarketSeries.Open.Last(i), ";", MarketSeries.Close.Last(i));
            }
        }


        protected override void OnBar()
        {

        }

        protected override void OnStop()
        {
            // Put your deinitialization logic here
        }
    }
}

Hi Panagiotis,

Good to know that it is already available to run robot on Renko or Range timeframes. Anyhow I prefer Renko as indicator beacause it is more flexible.

Investigating further more my issue reported above I found that Robot instance at start-up downloads certain amout of historical data depending on selected timeframe. For example for D1 it is ~73 candles, for H1 it is ~125 candles, for M1 it is ~1400 candles. It is accordingly 73 days, 5 days and 1 day. It explains why I can get only few archival bricks when my robot is set to M1 timeframe. 

Is is possible to configure Robot instance to obtain specific amount archival data ? Based on my knowledge of other broker API, it was for example possible to get up to 1 month of data for M1 and 6 months of data for D1 timeframe. 

Thanks

Sylwester

Dear Panagiotis, 

is there any way to backtest with range bars or renko? 

With built in range and renko I cant, is it possible somehow with an indicator?

Also, when trying to use the indicator I get this error: 

Error CS0246: The type or namespace name 'Renko' could not be found (are you missing a using directive or an assembly reference?)

How can I solve it?

Hi Martin,

Backtesting for Range/Renko is not available yet. Regarding the error, it seems you have not referenced the indicator.

Thank you Panagiotis. 

Could you please take a look a this simple code? can´t find the error: 

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


namespace cAlgo.Robots
{
    [Robot(TimeZone = TimeZones.UTC, AccessRights = AccessRights.None)]
    public class Range_Franki_v1 : Robot
    {
        [Parameter(DefaultValue = 0.0)]
        public double Parameter { get; set; }

        [Parameter("Renko Pips", DefaultValue = 10)]
        public double RenkoPips { get; set; }

        public int BricksToShow = 100;
        private Renko renko;


        protected override void OnStart()
        {
            {
                Print("ON-ST-(renko O;C) [", i, "]: ", MarketSeries.Open.Last(i), ";", MarketSeries.Close.Last(i));
            }
 

        }

        protected override void OnTick()
        {
            // Put your core logic here
        }

        protected override void OnStop()
        {
            // Put your deinitialization logic here
        }
    }
}

Hi Martin,

Did you add a reference to the Renko indicator in the project. Also apparently i variable is not declared. Did you just copied and pasted the code from somewhere else?
