RE:

I will try that, thank you.

Should there by any adjustments in case of running the cBot on a back test?

No, just load the symbol and its bars on your cBot OnStart method and you will be able to use it.

RE: RE: RE:

Hello

I have failed converting my code from a single to multi symbol. Perhaps you can attach a code sample of how you converted one of cTrader cBot samples (such as Sample Aligator, Sample Bears Power etc.) from single to multi symbol. An important note: The code must support running on a back test as well the same way (meaning one chart will run several symbols).

Thanks

Hi,

Here is the sample martingale cBot that works on two symbols, you must provide the symbol names:

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

namespace cAlgo
{
    [Robot(TimeZone = TimeZones.UTC, AccessRights = AccessRights.None)]
    public class SampleMartingalecBot : Robot
    {
        [Parameter("Initial Quantity (Lots)", Group = "Volume", DefaultValue = 1, MinValue = 0.01, Step = 0.01)]
        public double InitialQuantity { get; set; }

        [Parameter("Stop Loss", Group = "Protection", DefaultValue = 40)]
        public int StopLoss { get; set; }

        [Parameter("Take Profit", Group = "Protection", DefaultValue = 40)]
        public int TakeProfit { get; set; }

        [Parameter("First Symbol", Group = "Symbols")]
        public string FirstSymbolName { get; set; }

        [Parameter("Second Symbol", Group = "Symbols")]
        public string SecondSymbolName { get; set; }

        private Random random = new Random();

        protected override void OnStart()
        {
            Positions.Closed += OnPositionsClosed;

            var firstSymbol = Symbols.GetSymbol(FirstSymbolName);

            ExecuteOrder(InitialQuantity, firstSymbol, GetRandomTradeType());

            var secondSymbol = Symbols.GetSymbol(SecondSymbolName);

            ExecuteOrder(InitialQuantity, secondSymbol, GetRandomTradeType());
        }

        private void ExecuteOrder(double quantity, Symbol symbol, TradeType tradeType)
        {
            var volumeInUnits = symbol.QuantityToVolumeInUnits(quantity);
            var result = ExecuteMarketOrder(tradeType, symbol.Name, volumeInUnits, "Martingale", StopLoss, TakeProfit);

            if (result.Error == ErrorCode.NoMoney)
                Stop();
        }

        private void OnPositionsClosed(PositionClosedEventArgs args)
        {
            Print("Closed");

            var position = args.Position;

            if (position.Label != "Martingale") return;

            var symbol = Symbols.GetSymbol(args.Position.SymbolName);

            if (position.GrossProfit > 0)
            {
                ExecuteOrder(InitialQuantity, symbol, GetRandomTradeType());
            }
            else
            {
                ExecuteOrder(position.Quantity * 2, symbol, position.TradeType);
            }
        }

        private TradeType GetRandomTradeType()
        {
            return random.Next(2) == 0 ? TradeType.Buy : TradeType.Sell;
        }
    }
}

All you have to do is subscribe to the Tick event for each symbol you want.

This thread talks about it for indicators, but it's the same for cBots:

Example: Bars.Tick += YourOnTickEventMethod;

RE: RE: RE: RE: RE: RE: RE:

My original single symbol cBot has dozens of private members (strings, integers, etc.). All those members were designed for a single symbol. Now that there are many symbols, each of them should have a different value per symbol. Is there an easy straight forward way to convert all the members from single to multi symbol?

Thanks

Yes.

Add [] onto the end of them to declare them as arrays.

int[]

double[]

etc etc

[0] is the first symbol's value, [1] is the second symbol's, so on and so forth. Hopefully after that, you won't have to make too many other changes to your code depending on how it's written.
