Hi firemyst,

I would just use a boolean flag indicating if the Calculate() method has been executed.

Hi koktos632,

Change your cBot access rights to FullAccess. See below

[Robot(TimeZone = TimeZones.UTC, AccessRights = AccessRights.FullAccess)]

Hi firemyst,

1) Timer event should work as well. 

2) We had to make this change to fix other issues with indicators not being updated after reconnections

Hi w.b.z,

Unfortunately without a code sample to reproduce the problem we cannot determine what is the reason of the exception.

Hi Tengu,

See an example below

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

namespace cAlgo
{
    [Cloud("Fast MA", "Slow MA", FirstColor = "Aqua", Opacity = 0.5, SecondColor = "Red")]
    [Indicator(IsOverlay = true, TimeZone = TimeZones.UTC, AccessRights = AccessRights.None)]
    public class CloudExample : Indicator
    {
        [Parameter("Fast MA Period", DefaultValue = 21)]
        public int FastMaPeriod { get; set; }

        [Parameter("Slow MA Period", DefaultValue = 50)]
        public int SlowMaPeriod { get; set; }

        [Output("Fast MA", LineColor = "#FF6666")]
        public IndicatorDataSeries FastMaResult { get; set; }

        [Output("Slow MA", LineColor = "#0071C1")]
        public IndicatorDataSeries SlowMaResult { get; set; }

        SimpleMovingAverage FastMa;
        SimpleMovingAverage SlowMa;


        protected override void Initialize()
        {
            FastMa = Indicators.SimpleMovingAverage(Bars.ClosePrices, FastMaPeriod);
            SlowMa = Indicators.SimpleMovingAverage(Bars.ClosePrices, SlowMaPeriod);
        }

        public override void Calculate(int index)
        {
            FastMaResult[index] = FastMa.Result[index];
            SlowMaResult[index] = SlowMa.Result[index];
        }
    }
}

Hi firemyst,

In 3.7 all output series are cleared after initialization. All value assignments in output series should take place inside Calculate method.

Hi 66281850,

It means that you are using wrong credentials. Make sure that refresh_token, client_id and client_secret are correct.

Hi 66281850,

If you manually get the initial token, then everything else can be done automatically. No further user interaction is required.

Hi 66281850,

There is no way to get a token automatically. The user needs to give his explicit permission at least once. After you receive the token, you can use the refresh token to automatically refresh your token without user interaction.

The Optimisation is crashing even though exactly the same cBot works in Backtesting. For me the issue is in the time frame e.g. when I remove the timeframe description from the description of the indicator, Optimisation starts working e.g.

the code lines (in protected override void OnStart()) are:
            Bars M15 = MarketData.GetBars(TimeFrame.Minute15);
           _abd = Indicators.GetIndicator<abd>(M15, abd_Period, abd_Signal);

If I remove M15, the Optimisation starts working.

Hi TzvetomirTerziysky,

Can you post the complete cBot code?

1. Optimization may have indeed finished. The parameters are different across different runs, however I have no way of seeing which parameters are optimal as all the results are zeroed.

2. When I press "play" the optimizer quickly goes through the sequence of run numbers and stops at 574 and shows the screen above.

3. cBot runs well and two optimisations completed successfuly on 3.6

4. I restarted cTrader, once automatically during update, once manually. I also removed the cBot instance and assigned it again. No change.

5. cBot is closed source.

My guess is that this is some kind of cache issue. Can I manually scrub the optimizer cache and start again?

Hi thank you for the reply.

 

This is what I see and cannot unsee - there is no way for me to restart or resume the optimization process:

Hi Victor,

Can you post some screenshots as well for us to understand the issue?

This is probably an issue with the cBot's code. Can you post the source code?
