Hi,

Does it happen only when you subscribe to 80 symbols or it happens always?

Can you try without subscribing to any symbol or just subscribe to 1 symbol, see if it gets disconnected or not.

RE: Code is crashing cTrader

jani said:

Hello,

 

I tried to use below in an indicator:

Print("{0} bar on the chart. Loading 10 000 bars", Bars.Count);
while (Bars.Count < 10000)
{
    var loadedCount = Bars.LoadMoreHistory();
    Print("Loaded {0} bars", loadedCount);
    if (loadedCount == 0)
        break;
}
Print("Finished, total bars {0}", Bars.Count);

and it practically crashed my cTrader every time I compiled the code while the indicator was attached to a 1H chart.

Hi,

I just tested your code on Spotware cTrader beta for EURUSD and GBPUSD H1 and it worked fine.

But there is an issue with your code, what if the symbol doesn't have that number of bars? then you will end up with an infinite loop which will crash your cTrader.

You don't know how many bars are available, so if you use a fixed number and symbol doesn't had that number of bars then it will crash your platform.

Hi,

Each instance of a cBot runs separate from others, one can't have any effect on other running cBots.

Most probably something is wrong with your cBot code, and its not related to running multiple instances.

You should use unique labels for each of your running cBot instances, and use it to only manage the positions and orders that were opened by that instance.

Please post your cBot code then we will be able to help you.

Regarding debugging multiple running instances, right now there is no feasible way to do this.

Hi,

Sorry, I misunderstood you, I thought you want to get the current back test time on a cBot.

The close time of a bar is the open time of next bar, so there is no need for an extra data collection.

For indicators, the calculate method is called once for each historical bar, and then it's called for each tick.

So for indicators if you call the Server.Time during historical bars it should return the current time not the time of that bar, and that's the correct behavior not a bug.

>>>"The close time of a bar is the open time of next bar" 
Yes, this is true for historical bars, but not for the Last Bar (when IsLastBar == true). If I have set a time frame of lets say 1 hour, there is a time delay of max. 1 hour until I get the current time.  

>>>and then it's called for each tick.
Exactly! And I just need the accurate time of this "each tick". 

So again my question:
How do I get the accurate current back test time on an indicator for each tick after IsLastBar == true which is Corresponding to Bars.ClosePrices[index]???

 

Hi,

This issue will be resolved in cTrader 4.2.

RE: Can I backtest strategy with daily data?

duongphuongtrinh92 said:

Hi Spotware,

I would like to backtest a swing trading strategy using Daily Close Price. And the problem is I do not have 1-minute data csv file, I only have daily data. Can I backtest the strategy using this daily csv file?

No, you can't.

You can only import M1 bars data or use the server data.

Hi,

Try this:

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

namespace cAlgo.Robots
{
    [Robot(TimeZone = TimeZones.UTC, AccessRights = AccessRights.None)]
    public class NewcBot : Robot
    {
        [Parameter(DefaultValue = 0.0)]
        public double Parameter { get; set; }

        [Parameter("Periods", DefaultValue = 14)]
        public int Periods { get; set; }

        private RelativeStrengthIndex diffRSI;

        private IndicatorDataSeries nasdow;

        private Bars _nasdaqSeries, _dowjonesSeries;

        protected override void OnStart()
        {
            _nasdaqSeries = MarketData.GetBars(TimeFrame, "US TECH 100");
            _dowjonesSeries = MarketData.GetBars(TimeFrame, "US 30");

            nasdow = CreateDataSeries();

            diffRSI = Indicators.RelativeStrengthIndex(nasdow, Periods);
        }

        protected override void OnTick()
        {
            var index = Bars.Count - 1;

            var dowjonesSeriesIndex = _dowjonesSeries.OpenTimes.GetIndexByTime(Bars.OpenTimes[index]);
            var nasdaqSeriesIndex = _nasdaqSeries.OpenTimes.GetIndexByTime(Bars.OpenTimes[index]);

            nasdow[index] = _dowjonesSeries.ClosePrices[dowjonesSeriesIndex] - _nasdaqSeries.ClosePrices[nasdaqSeriesIndex];
        }
    }
}

The "nasdow" series contains the subtraction result of two other series, and you can use it on any indicators.

You can't do that now, but if you want to you can write each cBot pass statistics and parameters on a file when OnStop method is called, so you have to code it by your self.

Hi,

You should use different values for your cBot "Instance Name" parameter for each instance, otherwise all the instances will only open one position.

Or you should change the code at:

        private void OpenPosition(string Label, TradeType TradeDirection)
        {
            //Calculate Trade Amount base on the ATR

            var PrevATR = Math.Round(atr.Result.Last(1) / Symbol.PipSize);
            var PerTradeadjust = PerTrade / 100;
            var TradeAmount = (Account.Equity * PerTradeadjust) / (PrevATR * Symbol.PipValue);
            TradeAmount = Symbol.NormalizeVolumeInUnits(TradeAmount, RoundingMode.Down);
            ///var cBotPositions = Positions.FindAll(InstanceName); not used
            if (Positions.Count(x => x.Label == InstanceName) == 0)
            {
                ExecuteMarketOrder(TradeDirection, SymbolName, TradeAmount, InstanceName, null, null);
            }
        }
