auto close

Hi I have built an code that says if open trade at 21.30 then close positions.

It works in backtesting but not live at my demo account, what is wrong?

if (utcTime.Hour == 19 && utcTime.Minute >= 30) // 19:30 UTC corresponds to 21:30 UTC+2
            {
                if (isTradeInitiated)
                {
                    CloseOpenTrades();
                }
                Stop();
            }
        }

        private void CloseOpenTrades()
        {
            foreach (var position in Positions)
            {
                if (position.Label == Label)
                {
                    ClosePosition(position);
                }
            }
        }
