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

namespace cAlgo
{
    [Indicator(IsOverlay = false, TimeZone = TimeZones.UTC, AccessRights = AccessRights.None)]
    public class SimpleIndicator : Indicator
    {
        [Parameter(DefaultValue = "EURUSD")]
        public string symbName { get; set; }

        [Output("Main")]
        public IndicatorDataSeries Result { get; set; }

        private MarketSeries ms;

        protected override void Initialize()
        {

            ms = MarketData.GetSeries(symbName, TimeFrame);
        }

        public override void Calculate(int index)
        {
            DateTime dt = MarketSeries.OpenTime[index];
            int indexMS = ms.OpenTime.GetIndexByTime(dt);

            Result[index] = ms.Close[indexMS];
        }
    }
}

Here is an example with a simple indicator that just plot the close of other symbol.

If we add this indicator to the chart while we are in visual backtesting, on cTrader 3.6 there is no problem, indicators load and work normally, but on the 3.7 indicators never load.

Hi,

I have the exact same problem, very annoying. 

I'm using cTrader 3.8.

Please, Might you give us any feedback ?

Just to add to the chorus, I am trying to do something similar in 3.8, so any updates/information would be great!

In fact, some of the standard Indicators, like SwingIndex, simply don't seem to display in tick T1 view, in my cTrader 3.8 :

Is this normal / to be expected, or is something wrong?

Hi dubmocio,

This is an old issue which I cannot reproduce at the moment. Can you please provide more information about your issue so that we can reproduce?

Hi ctid2514471,

This seems to be irrelevant to the issue described in this post. Can you please create a new thread?

Hi,

It is quite curious..

I tested in visual bakstesting my own multisymbol indicator during the weekend when the markets were closed. It didn't work.

I repeated the test yesterday. It worked fine.

Same today. It's working fine.

Is there any possibility that a multisymbol indicator visual backtest works only when the markets are open ?

I did the above tests even with the sample indicator posted by sandrotame1900 in this post. Same results...

Thanks

Today Ctrader updated itself to version 4.0. Same indicators tested above are not working anymore in visul backtesting... how could it be possible ?!? is it just a coincidence ?

Thanks

Hi dubmocio,

I asked for more information above but you did not provide it. Unfortunately we cannot help you if we do not get more information, like the indicator code and exact steps to reproduce this issue.

In my previous post I specifically wrote : '' I did the above tests even with the sample indicator posted by sandrotame1900 in this post. Same results...'' meaning that both my own indi and the one posted in this very first post are giving me the same result. Just take that code, as I did to test the issue. Yesterday it was not working for me. On the contrary it worked 2 days ago. I also tried to substitute MarketSeries with the new API Bars. Same results. Yesterday it didn't work. 2 days ago it did.

Thanks.
