Hi marian.kosa,

Thanks for posting in our forum. It is not clear to me what is the problem. Why do you want to replace index? What are you trying to do?

Best Regards,

RE:

I want to extract price from that indicator to use it later as stoploss.

I am trying to figure out what that index represent, because with it, i am getting several errors, depending how i adjust the code. 
For example "Error CS0115: 'cAlgo.bot.OnBar(int)': no suitable method found to override" or "Error CS0103: The name 'index' does not exist in the current context"

Current simplified code:

using System.Linq;
using cAlgo.API;
using System.IO;
using System.Collections;
using System.Collections.Generic;
using cAlgo.API.Indicators;
using cAlgo.API.Internals;
using cAlgo.Indicators;

namespace cAlgo
{
    [Robot(TimeZone = TimeZones.UTC, AccessRights = AccessRights.FileSystem)]

    public class bot: Robot
    {
        [Parameter("Volume", DefaultValue = 10000)]
        public int volume { get; set; }

        [Parameter(DefaultValue = 15, MinValue = 1)]
        public int TakeProfit { get; set; }

        public FractalChaosBands _fractalChaosBands;

        protected override void OnBar()
        {
            _fractalChaosBands = Indicators.FractalChaosBands();

                double FL = _fractalChaosBands.Low[index];
                double FH = _fractalChaosBands.High[index];

                if (***)
                {
                    ExecuteMarketOrder(TradeType.Buy, SymbolName, volume, "BOT", FL, TakeProfit, "buy");
                }

                if (***)
                {
                    ExecuteMarketOrder(TradeType.Sell, SymbolName, volume, "BOT", FH, TakeProfit, "sell");
                }            
        }
    }
}

Hi marian.kosa,

The index represents the index of the current bar being calculated and as you can see it is passed as a parameter to the Calculate method. So you can use it only inside this method. It is a local variable. If you want to access the values of the indicator inside the cBot, you should consider using Last() method.

RE:

I was trying to Last(), but i probably wrote it wrong. 
Anyway i wrote it that way now "double FL = _fractalChaosBands.Low.Last(1);"

Aaand as i was writing my next question, i realized, that i was writing stoploss in price, not in pips....

Thanks, for your time, I should be able to continue from here.
