Arbitrage bot

GM

i build an indicator to show the Theoretical price of EURJPY on the chart to get a possible Arbitrage if there is an imbalance of the real price. it calclates with the EURUSD and USDJPY Price in realtime from cTrader broker data. 

It behaves like a third price Line

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

namespace cAlgo.Indicators
{
    [Indicator(AccessRights = AccessRights.None)]
    public class Arbitrage_Theoretical_Price_EURJPY : Indicator
    {
        private Symbol eurusd;
        private Symbol usdjpy;
        private Symbol eurjpy;

        [Output("Theoretical Price", LineColor = "Blue")]
        public IndicatorDataSeries TheoreticalPrice { get; set; }

        protected override void Initialize()
        {
            eurusd = Symbols.GetSymbol("EURUSD");
            usdjpy = Symbols.GetSymbol("USDJPY");
            eurjpy = Symbol; // Automatically fetch the EURJPY symbol for the current chart
        }

        public override void Calculate(int index)
        {
            double eurusdBid = eurusd.Bid;
            double usdjpyBid = usdjpy.Bid;
            double eurusdAsk = eurusd.Ask;
            double usdjpyAsk = usdjpy.Ask;

            double theoreticalBidPrice = eurusdBid * usdjpyBid;
            double theoreticalAskPrice = eurusdAsk * usdjpyAsk;
            double theoreticalPrice = (theoreticalBidPrice + theoreticalAskPrice) / 2;

            for (int i = 0; i <= index; i++)
            {
                TheoreticalPrice[i] = theoreticalPrice;
            }
        }
    }
}

Now i want to automatically arbitrage it if the price is above or below from the ask or bid price by 0,025% to open a Long or short and setting a Target at the Theoretical price line. Now my problem is that the bot  can't dfind it trough the name and i dont know how to code the bot for my plan. the following code is below:

______

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

namespace cAlgo.Robots
{
    [Robot(TimeZone = TimeZones.UTC, AccessRights = AccessRights.None)]
    public class ArbitrageBot : Robot
    {
        private Arbitrage_Theoretical_Price_EURJPY theoreticalPriceIndicator;
        private Symbol eurjpy;

        private const double ThresholdPercentage = 0.025; // 0.025%

        protected override void OnStart()
        {
            // Initialize the symbol
            eurjpy = Symbol; // Automatically fetch the EURJPY symbol for the current chart

            // Initialize the theoretical price indicator
            theoreticalPriceIndicator = Indicators.GetIndicator<Arbitrage_Theoretical_Price_EURJPY>();
        }

        protected override void OnTick()
        {
            // Get the current Bid and Ask prices of EURJPY
            double currentBidPrice = eurjpy.Bid;
            double currentAskPrice = eurjpy.Ask;

            // Get the theoretical price from the indicator
            double theoreticalPrice = theoreticalPriceIndicator.TheoreticalPrice.Last(1);

            // Calculate the percentage difference between theoretical and actual prices
            double bidDifference = (theoreticalPrice - currentBidPrice) / currentBidPrice * 100;
            double askDifference = (currentAskPrice - theoreticalPrice) / theoreticalPrice * 100;

            // Check if the differences exceed the threshold
            if (bidDifference >= ThresholdPercentage)
            {
                // Open a long position (buy) since the theoretical price is lower than the current bid price
                var positionSize = 1; // Define your position size here
                var stopLoss = currentBidPrice - (currentBidPrice * 0.01); // Example stop loss (1% away)
                var takeProfit = theoreticalPrice; // Set the theoretical price as the target

                ExecuteMarketOrder(TradeType.Buy, eurjpy.Name, positionSize, "ArbitrageBot", stopLoss, takeProfit);
            }
            else if (askDifference >= ThresholdPercentage)
            {
                // Open a short position (sell) since the theoretical price is higher than the current ask price
                var positionSize = 1; // Define your position size here
                var stopLoss = currentAskPrice + (currentAskPrice * 0.01); // Example stop loss (1% away)
                var takeProfit = theoreticalPrice; // Set the theoretical price as the target

                ExecuteMarketOrder(TradeType.Sell, eurjpy.Name, positionSize, "ArbitrageBot", stopLoss, takeProfit);
            }
        }
    }
}
