Optimization multi symbols on Tick

Hello everyone, I hope someone can help me.

I'm testing some ideas with multisymbols and I can run the optimization on the bar, but I can't run it on every tick, this is the code:

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

namespace cAlgo.Robots
{
    [Robot(TimeZone = TimeZones.UTC, AccessRights = AccessRights.None)]
    public class TestBot : Robot
    {
        [Parameter("Stop Loss", Group = "Test", DefaultValue = 80, MinValue = 1, MaxValue = 10000, Step = 1)]
        public int Sl { get; set; }
        [Parameter("Take Profit", Group = "Test", DefaultValue = 80, MinValue = 1, MaxValue = 10000, Step = 1)]
        public int Tp { get; set; }

        public Symbol[] MySymbols;

        protected override void OnStart()
        {
            MySymbols = Symbols.GetSymbols("EURUSD", "GBPUSD");
            foreach (var symbol in MySymbols)
            {
                var bars = MarketData.GetBars(TimeFrame, symbol.Name);
                bars.BarOpened += Bars_BarOpened;
            }
        }

        private void Bars_BarOpened(BarOpenedEventArgs obj)
        {
            if (obj.Bars.Last(1).Close > obj.Bars.Last(1).Open)
            {
                ExecuteMarketOrder(TradeType.Buy, obj.Bars.SymbolName, 1000, "Label", Sl, Tp);
            }
            else
            {
                ExecuteMarketOrder(TradeType.Sell, obj.Bars.SymbolName, 1000, "Label", Sl, Tp);
            }
        }
    }
}
