How to get ask price

Hi robustby,

The ask price is not available. Bars are created using bid prices. To get ask prices you need to get the tick data using MarketData.GetTicks() and loop through the ticks to find the lowest for the bar's period.

Hi robustby,

Here is an example of how to load all ticks for the bars loaded on your 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
    {
        [Parameter(DefaultValue = 0.0)]
        public double Parameter { get; set; }

        protected override void OnStart()
        {
            var ticks = MarketData.GetTicks();
            while (ticks[0].Time > Bars[0].OpenTime)
            {
                ticks.LoadMoreHistory();
                Print("Loaded till " + ticks[0].Time);
            }
            Print("Ticks loaded");
        }

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

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

Thank you so much for the example. Can you check if I'm right? If I want to get lower Ask price I'm doing following:

            var ticks = MarketData.GetTicks();
            while (ticks[0].Time > Bars[0].OpenTime)
            {
                ticks.LoadMoreHistory();
                Print("Loaded till " + ticks[0].Time);

            }
            Print("Ticks loaded");

            int tickIndex = 1;
            int NumberOfTicks = 10000;
            double GetAskLow = ticks[0].Ask; //get last Ask tick in the left of chart
            for (int i = tickIndex; i < ticks.Count; i++)
            {
                if (ticks[i].Ask < GetAskLow)
                {
                    GetAskLow = ticks[i].Ask;
                }

            }
            Print("GetAskLow = ", GetAskLow);

Also, I have some questions:

1) If I want to use only last 10000 ticks, how better load it? Or if I want use ticks data for only 50 last bars at the chart?

2) I must use MarketData.GetTicks() & ticks.LoadMoreHistory() for every time when new tick appears? Please explain how it works.

Hi robustby,

It seems correct to me

1) If I want to use only last 10000 ticks, how better load it? Or if I want use ticks data for only 50 last bars at the chart?

You should load until this condition is me e.g.

while (ticks.Count < 100000)

I must use MarketData.GetTicks() & ticks.LoadMoreHistory() for every time when new tick appears? Please explain how it works.

The list is not updated with every incoming tick. Therefore you should make the respective arrangements if this is something that is important for you i.e. add the new ticks to the list.
