Hi Matt,

The code below should work on the latest version of cTrader

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

namespace cAlgo
{
    [Indicator(IsOverlay = true, TimeZone = TimeZones.UTC, AccessRights = AccessRights.None)]
    public class BidAsk : Indicator
    {
        [Parameter("To Infinite", DefaultValue = true)]
        public bool ToInfinite { get; set; }

        [Parameter(DefaultValue = 0)]
        public int Displacement { get; set; }

        [Output("Ask", Color = Colors.DodgerBlue, PlotType = PlotType.DiscontinuousLine)]
        public IndicatorDataSeries SymbolAsk { get; set; }

        [Output("Bid", Color = Colors.Red, PlotType = PlotType.DiscontinuousLine)]
        public IndicatorDataSeries SymbolBid { get; set; }

        protected override void Initialize()
        {
            // Initialize and create nested indicators
        }

        public override void Calculate(int index)
        {
            if (!IsLastBar)
                return;

            SymbolBid[index + Displacement - 1] = double.NaN;
            SymbolAsk[index + Displacement - 1] = double.NaN;

            for (int i = ToInfinite ? -MarketSeries.Close.Count : Displacement; i < 200; i++)
            {
                SymbolBid[index + i] = Symbol.Ask;
                SymbolAsk[index + i] = Symbol.Bid;
            }
        }
    }
}

Best Regards,

Panagiotis

I could be wrong, but I think your reversed the Bid and Ask....
If you put the indicator on a chart,, The Ask is cTraders Bid.. and vice versa.. The Bid is cTraders Ask..
