Hi there,

Hi,

it's quite easy.

a) run any optimalization via remote desktop, change cpu core usage to 100% and/or sort results by any cryteria,

logout from rdp session and login, you should see problem

b) or run cbot in real mode, draw buttons in “onstart”, logout and login,

In my case this object (border→stackpanel→button) was reduced to “0” dimension (i see small dot with colour of my border).

This problem starts about year ago after some update of cTrader. Before works without problems.

I checked 3 pc with 3 different os (W10,W11, Windows Server 2016).

No. The problem is still there. The data is loading each time for the same time period while backtesting.

If I want to backtest for more than 3 years, it won't even load the data. And I should be able to backtest on tick data since 2016.

I have enough ram and enough virtual ram on my computer.

I resolve my problem:

a) uninstall cTrader

b) and most important : remove cTrader folder in Documents (not cAlgo, only cTrader)

c) install cTrader

Hi,

 

Yesterday I ran the backtesting (tick data) from 2016 to July 2023. Although I ran it many times before, the data was loading again for a long time. I thought this is just because of the new update to cTrader 4.8.15 and I'll just have to load the data once for the same period. But today I restarted my computer and wanted to run the backtesting for the same time period and the data is loading again.

Will the data be newly loaded each time now with this cTrader update, although I already ran the same backtesting for the same time period?

 

Please advise

 

EDIT: I noticed something else.

I just restarted my computer again. When I went to backtesting and only pressed the play button the data didn't load. It started backtesting. But when I only add one more day to the time period it loads the whole data again for the whole time period. It should only load the data for the newly added day to the time period. So this should be quite fast to load the data.

Example. I want to backtest the bot from 12.1.2023 to 1.7.2023. If I already backtested the time period before the data won't load newly. It will start backtesting right away. But if I only add one more day, so from 11.1.2023 to 1.7.2023 it will load the data for the entire period and will take a long time.

Am I doing something wrong?

Hi,

not sure what you want to achieve with this, but in my case there is a timeframe parameter available out of the box for optimization. No need to add one. 

If you just need an additional time frame parameter for a second timeframe in your bot, you can simply use the type TimeFrame for your parameter (see example below). Unfortunately I cannot set a default using DefaultValue = TimeFrame.Minute15. This does not compile. And secondly when you use my example the TimeFrame parameter is not available for optimization. Only the one provided by cTrader Desktop works for me. 

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using cAlgo.API;
using cAlgo.API.Collections;
using cAlgo.API.Indicators;
using cAlgo.API.Internals;

namespace cAlgo.Robots
{
    [Robot(AccessRights = AccessRights.None)]
    public class Test : Robot
    {
        [Parameter("My Time Frame")]
        public TimeFrame InpTimeFrame { get; set; }

        protected override void OnStart()
        {
        }

        protected override void OnTick()
        {
        }

        protected override void OnStop()
        {
        }
    }
}

 

Do You see difference ?

Hi there,

From my experience, there is an obvious mismatch between your setups that you are missing. Happened to me many times :) Usually is in front of your eyes. Blaming the CPUs is a bit far fetched at the moment. Make sure you are running the same versions of cTrader. Then you could try a clean installation of cTrader on both machines to make sure nothing is cached.

I found reason. On e2-900 I tested on real account from FXpro, 

I make some tested on 5900x machine with real not demo accounts, and I get almost identical results like on e2-900.

Hi fx.pro,

The problem is here

I posted working version , but I have problem in importing values of this indicator to my cbot. This is part of my cbot :

        private StochbyPem stoch;
        private ADXbyPem adx;
        

        protected override void OnStart()
        {

            
            adx = Indicators.GetIndicator<ADXbyPem>(Adx_per, Adx_ma_per, Adx_skew, Adx_lb);
            stoch = Indicators.GetIndicator<StochbyPem>(Period_stoch, kPeriods_D, kSlowing_K, stoch_open_skew, stoch_close_skew);

          

        }
        protected override void OnBar()
        {
            

            Print(adx.BUYcond);
            Print(adx.adx_h);
            Print(adx.Adx_ma_n.LastValue);

As You see first print causes always false (but indicator show properly values),

second naN

third : rest of errors.

Indicator is registered properly and i checked almost all posibilties for accesing to values of this indicator (Last, Lastvalue etc).

The same proplem is with my second custom indiator (stoch).

Can You give a little hint.

Thanks,
