Hi pmcarvalho,

From where do you want to access the prices? From the chart? If yes then just scroll back to the specific date.

Best Regards,

Hi Panagiotis Charalampous
I am building a bot for statistics and caching.
I already tried to use this: "Chart.ScrollXTo ([date]);"
But it doesn't go that far.  It probably stops at the first value it has available on the chart.
Any idea?

Thanks

Pedro

Hi Pedro,

Indeed this is true. See below a workaround

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
    {
        [Parameter(DefaultValue = 0.0)]
        public double Parameter { get; set; }

        protected override void OnStart()
        {
            Chart.ScrollChanged += OnChartScrollChanged;
            if (MarketSeries.OpenTime[0] > new DateTime(2014, 1, 1))
            {
                Chart.ScrollXTo(MarketSeries.OpenTime[0]);
            }
        }

        void OnChartScrollChanged(ChartScrollEventArgs obj)
        {
            if (MarketSeries.OpenTime[0] > new DateTime(2014, 1, 1))
            {
                Chart.ScrollXTo(MarketSeries.OpenTime[0]);
            }
        }



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

Best Regards,

Thanks.

It worked.

By the way. There is a way to pass the date to the handler (OnChartScrollChanged), instead of beeing hardcoded (new DateTime(2014, 1, 1))?

Thanks

Hi Pedro,

No you cannot but I do not see the need. You can have a global variable for this.
