Notice the spike in volume on Friday. The spike in volume is occurring right at the prior zone where a similar green candle with volume spike happened few weeks ago. Price then correction about 10% from the highs.
The inability to cross the recent highs, despite the volume spike, makes me slightly cautious / worried. A red candle on Monday (Oct.17) would mean that the stock is still not attracting big buying interest.
Better to wait for the price to clear the green line at 452+ before considering big ticket long positions.
