Need Help: Multi Time Frame Alert

Hi I am a newbie in coding and I was wondering if somebody can assist me with my problem. Is there any way I could create an alert for different time frames? The gist of my indicator is just to look for a certain pattern on the chart, but.. I want to be alerted on this for different timeframes. I have looked around the forums but mostly what I found was they are just displaying indicators from various timeframes. I do not want that, I just want to be alerted, should I be using the same script? Please help to give me some advise, below is a sample of my script. Thank you.

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 Trial : Indicator
    {

        [Parameter("Alert File", DefaultValue = "c:\\windows\\media\\Windows Hardware Insert.wav")]
        public string MediaFile { get; set; }

        [Parameter("Alert Sounds", DefaultValue = true)]
        public bool AlertNow { get; set; }

        private MarketSeries series1;
        private MarketSeries series5;


        protected override void Initialize()
        {
            series1 = MarketData.GetSeries(TimeFrame.Minute);
            series5 = MarketData.GetSeries(TimeFrame.Minute5);
        }


        public override void Calculate(int index)
        {
       
            var index1 = GetIndexByDate(series1, MarketSeries.OpenTime[index]);
            if (index1 != -1)
            {

                //just a sample
                   if 
                   {
                           if ((MarketSeries.Close[index1 - 1] <= MarketSeries.Open[index1 - 1]) & (MarketSeries.Close[index1 - 2] >= MarketSeries.Open[index1 - 2]))
                            {
                                if (AlertON)
                                {
                                    //my alert in M1 tf
                                    if (AlertNow)
                                    {
                                        Notifications.PlaySound(MediaFile);
                                    }

                                    break;
                                }
                           }
                    }
             }


            var index5 = GetIndexByDate(series5, MarketSeries.OpenTime[index]);
            if (index5 != -1)
            {

                //just a sample

                            {
                                if (AlertON)
                                {
                                    //my alert in M5 tf
                                    if (AlertNow)
                                    {

                    }
             }
                    

        private int GetIndexByDate(MarketSeries series, DateTime time)
        {
            for (int i = series.Close.Count - 1; i > 0; i--)
            {
                if (time == series.OpenTime[i])
                    return i;
            }
            return -1;
