The last fall came from 21750-800, with a bearish candle in the daily timeframe and the high at 21750. If it breaks this level tomorrow, then 21850 becomes an important resistance. If we get a good close above 21800 tomorrow, then it will resume its uptrend. If it falls after a gap up or gap down happens, then the range could be 21600-750 for tomorrow. Levels are marked on the chart.
