Hi ctid386599,

It is not clear to us what do you need.

1. What is custom renko? A cBot or an indicator? Can you post the code?
2. Why do you need data from earlier periods and how are these data related to the cBot/Indicator?  

If you give us some more information on what you are trying to do then we might be able to help you.

Best Regards,

Panagiotis

RE:

Hi Panagiotis,

I have  renko indicator  and a cbot  gets the renko  blocks.

If i want to run my bot between a given  time interval, the blocks are formed between that time interval.

it means at time =0, there is no brick yet. I would like to have bricks from  say 1 month earlier

Hi ctid386599,

Data for indicators is loaded for periods before the backtesting starts therefore you should not worry about this. You should havemany bricks created on starting your cBot. See example below.

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

namespace cAlgo.Robots
{
    [Robot(TimeZone = TimeZones.UTC, AccessRights = AccessRights.None)]
    public class NewcBot : Robot
    {
        private Renko _renko;

        protected override void OnStart()
        {
            _renko = Indicators.GetIndicator<Renko>(10, 100, 3, "SeaGreen", "Tomato");
            Print(_renko.Close.Count);
        }
        protected override void OnBar()
        {       
         
        }
        protected override void OnStop()
        {
            // Put your deinitialization logic here
        }
    }
}

Best Regards,
