Hi Waxy,

you just need to repeat the LoadMoreHistory() until you have enough history data.

API.Ticks symbolTicks;
DateTime firstDt = new DateTime(2020, 8, 1);

symbolTicks = MarketData.GetTicks();
while (symbolTicks[0].Time.CompareTo(firstDt) > 0)
{
     symbolTicks.LoadMoreHistory();
}

Maybe Panagiotis will post the snipplet in the API-Reference. I was looking for it before as well.

Cheers
GridSurfer

Thank you,

This works!

RE:

What I mean is that it takes me 10-15 seconds to load these symbols, not almost instantly, I'm using 30mbps.

Only after the first load, any refresh of the bot/indicator and the bars load instantly afterward (which again, it's great news).

Also, I think a good option would be to have an overload where we can specify how many bars to load, because many times a thousand daily bars is not really needed, is it possible?

And I'm since this is part of the update I thought it would be correct to ask about it in this thread, I'll leave it here and if needed I'll open a new thread, sorry about that.

Thanks for your support

RE: RE: RE:

Hello Panagiotis,

I'm trying out the following code,

using System.Collections.Generic;
using cAlgo.API;

namespace cAlgo
{
    [Indicator(IsOverlay = false, TimeZone = TimeZones.UTC, AccessRights = AccessRights.None)]
    public class NewIndicator : Indicator
    {
        private readonly List<Bars> _bars = new List<Bars>();
        private readonly string[] _mySymbols = {"EURUSD","GBPUSD","EURJPY","USDJPY","AUDUSD","USDCHF","GBPJPY","USDCAD","EURGBP","EURCHF"};

        protected override void Initialize()
        {
            Print("Initializing");

            foreach (var symbol in _mySymbols)
            {
                Print(string.Format("Loading Symbol {0}", symbol));
                MarketData.GetBarsAsync(TimeFrame.Hour, symbol, bar =>
                {
                    _bars.Add(bar);
                    Print(string.Format("{0} Loaded, Bars: {1}", bar.SymbolName, bar.Count));
                });
            }

            Print("End Initializing");
        }

        public override void Calculate(int index) { }
    }
}

I get the responses in the log in this order, doesn't seem to work properly to me, is this correct, or I'm I doing something wrong, is this the best way to do it? It takes about 16 seconds to load them all (don't get me wrong it's a big improvement), could it load faster?

Hello Spotware,

These are indeed great additions,

I see now that when I load an indicator that uses multiple MarketSeries (or now Bars) it takes much less than before, and this is great news, but at the start, it takes the same as before, so, I'd like to know if it's possible to improve or what's the best way now to load multiple series loading for indicators/bots during initialization, let's say I want to load 10 symbol bars, can I load these in parallel now?

 

Hi Xavier,

You can use MarketData.GetBarsAsync() and MarketData.GetTicksAsync() to get data asynchronously.

I think I have sorted this out, by building inside Visual Studio without clicking build again in cTrader the Debug mode will not be overridden.

I'm not sure if this is a bug or a feature, the text is shown above the price axis, how can I edit or fix this? Chart.Width should not consider this axis area.

Thanks for replying,

I'm sorry, what I was actually trying to suggest by improving RemoveChild() is that it should have an overload to just remove by index [Column,Row], or know by these if a "cell" has any child in it, we can make workarounds for it, but it would be nice to have it.

Thanks for the font tips as well.
Best Regards,
Xavier R.

Hello Panagiotis, thanks for your support.

Can you tell me which FamilyFont types are supported? it seems I have to guess, enums for this would be nice.

Another suggestion, the grid should be improved to access and edit objects by index [row, colum], I don't see options to do this, there are only options to remove entire rows or columns.

The .AddChild() property includes row, column parameters, but the .RemoveChild() does not.

I hope this or something similar gets added before 3.6 is released.

Thanks

Hello Spotware, thanks for these additions, they are really helpful.

I have two questions:

What is the "IsHitTestVisible" property for? can we get an example?

My second question might be a request also, it seems we can't modify the grid lines inside a Grid, it would be nice to change the style, width, and color, I can use BorderPanel to circumvent this issue for the moment.

Hello Panagiotis,

I apologize, let me explain:

It is supposed that this event is fired every time you scroll through the chart, right?, however, it's being fired constantly without any interaction with the chart whatsoever, it's a bit erratic, I'm not sure what triggers it.

My bad tho, I tried it and it doesn't work outside forms, the one built in cTrader is enough for most tasks I think.

You can do:
 

         protected override void OnStart()
        {
            Timer.Start(TimeSpan.FromMilliseconds(100));
        }
        
        protected override void OnTimer()
        {
            Print("Test");
        }

If you need more timers you could use the Timer inside System.Windows.Forms, I read that is also single threaded, read the documentation here:
https://docs.microsoft.com/en-us/dotnet/api/system.windows.forms.timer?view=netframework-4.7.2

The timers inside System.Timers are not single threaded and I think they're not safe.

Hello!

Please allow the use of Description Attribute to enums so they could be easily readable, i.e:
 

using System.ComponentModel; 

public enum MyEnum 
{ 
    [Description("value 1")] 
    Value_1, 
    [Description("value 2")]
    Value_2, 
    [Description("value 3")]
    Value_3
}

Thanks for your hard work.
