Hi social.trading,

Did you check if the specific part of the code is executed? If no, you should investigate the reason. If yes, please make sure that the sound file is in the correct location. It would be better to start with an empty indicator and try to make the sound play on each bar change. After that works successfully, add the functionality to the existing indicator.

Best Regards,

Panagiotis

Hi social.trading,

The way you have programmed it, it will play the sound only once and then it will stop working. You will need to reset the alreadyPlayed on the change of each bar. 

Best Regards,

Hi social.trading,

First of all it would be better if you could post the complete cBot code. It is not clear what is the code supposed to do. Then give us a clear explanation of what do you expect the cBot to be doing. Why do you have a loop? Also why do you need to have the sound playing inside the loop?

Best Regards,

Hi ctid712216,

As explained above, new orders can be placed automatically to restore the equity to equity ratio between the two accounts. For the specific trade you reported, there was a change in the strategy provider's balance that caused automatic trades to be executed on copying accounts to restore the equity to equity ratio.

Best Regards,

Hi social.trading,

The easiest solution to this would be to use a sound file that repeats the sound as many times as you want and just play it from the cBot once.

Yes you need to select the trendline tool for each line you want to draw.

Hi davewilson347,

If you are always getting an exception in these cases, you can always use a try catch statement to handle them.

Hi FireMyst,

First of all if you want to see any results at all you need to change

            double tsiDivisor = _divisor.Result[altIndex];
            double tsiDividend = _dividend.Result[altIndex];

to

            double tsiDivisor = _divisor.Result[index];
            double tsiDividend = _dividend.Result[index];

But then there is a major logical issue with your indicator. You are trying to do calculations for indicators using a different timeframe on the main indicator. This will result to wrong results due to different resolution of the available data.  

Example

            if (MarketSeries.TimeFrame != _marketSeries.TimeFrame)
            {
                altIndex = _marketSeries.OpenTime.GetIndexByTime(MarketSeries.OpenTime[index]);
            }

If MarketSeries.TimeFrame is h1 and _marketSeries.TimeFrame is m30 then when executing the following

_dataSeries[index] = _marketSeries.Close[altIndex] - _marketSeries.Close[altIndex - 1];

The last x values (let's say 14) of _dataSeries will contain sample data from the last 28 values of the _marketSeries.Close, since for every change of the index for h1, the index for m30 increases by 2 (print altIndex to understand what i man). Therefore this average

_longDividend = Indicators.MovingAverage(_dataSeries, 14, MaType);

will not be an average of the last 14 periods but the last 28 since it will average the last 14 sample values collected in _dataSeries.

Since you are using moving averages which are simple to code, it would be easier to do the calculations yourself rather than relying on cTrader indicators. Just loop through the custom timeframe data and calculate the MAs

Best regards,

Panagiotis

Ηι drayzen,

cTrader is a platform for CFD contracts which is a different market in many ways than exchanges. We already have an exchange product called cExchange which has a similar interface to cTrader and it is targeted to cryptocurrency exchanges.

Hi FireMyst,

As explained above, data series are not "attached" to any timeframe. It is just a series of doubles. If you want to feed them with data from a lower timeframe, you can do it. There is no time property on anything else that relates an item of the data series to a timeframe.

Hi Stephen,

Thanks for posting in our forum. We do not have a timeframe at the moment.
