What is the max size of the backtest log and can it be increased?

Hi lec0456,

The limit is ten thousand rows. If you need more, you can consider using a custom file and log your information there.

Hi lec0456,

Note that I am referring to replacing the Print function and writing to a text file instead. See below an example

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

namespace cAlgo.Robots
{
    [Robot(TimeZone = TimeZones.UTC, AccessRights = AccessRights.FileSystem)]
    public class NewcBot : Robot
    {
        private string fiName;
        private StreamWriter _fileWriter;
        protected override void OnStart()
        {
            _fileWriter = new StreamWriter("c:\\Users\\pcharalampous.CTRADER\\Documents\\log.txt");
            // Put your initialization logic here
        }

        protected override void OnTick()
        {
            _fileWriter.WriteLine(Symbol.Bid);
        }

        protected override void OnStop()
        {
            _fileWriter.Close();
        }
    }
}

Best Regards,
