Can add time filter ?

Part, can I add a start to this grid once the RSI reaches a given value? for example this one:

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

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

        [Parameter("Source", Group = "RSI")]
        public DataSeries Source { get; set; }

        [Parameter("Periods", Group = "RSI", DefaultValue = 14)]
        public int Periods { get; set; }

        [Parameter("Lower RSI Level", Group = "RSI", DefaultValue = 30, MinValue = 0, MaxValue = 50)]
        public int LRL { get; set; }

        [Parameter("Upper RSI Level", Group = "RSI", DefaultValue = 70, MinValue = 50, MaxValue = 100)]
        public int URL { get; set; }

        [Parameter("Take Profit in pips", Group = "TP SL", DefaultValue = 100)]
        public int TP { get; set; }

        [Parameter("Stop Loss in pips", Group = "TP SL", DefaultValue = 100)]
        public int SL { get; set; }

        private RelativeStrengthIndex rsi;

        protected override void OnStart()
        {
            rsi = Indicators.RelativeStrengthIndex(Source, Periods);
        }

        protected override void OnTick()
        {
            if (rsi.Result.LastValue < LRL)
            {
                Close(TradeType.Sell);
                Open(TradeType.Buy);
            }
            else if (rsi.Result.LastValue > URL)
            {
                Close(TradeType.Buy);
                Open(TradeType.Sell);
            }
        }

        private void Close(TradeType tradeType)
        {
            foreach (var position in Positions.FindAll("SampleRSI", SymbolName, tradeType))
                ClosePosition(position);
        }

        private void Open(TradeType tradeType)
        {
            var position = Positions.Find("SampleRSI", SymbolName, tradeType);
            var volumeInUnits = Symbol.QuantityToVolumeInUnits(Quantity);

            if (position == null)
                ExecuteMarketOrder(tradeType, SymbolName, volumeInUnits, "SampleRSI", SL, TP);
        }
    }
}
