JSG could a failure at the old ceiling trigger a deep slide?Johnson Service Group PLCLSE_DLY:JSGStockso_SimplePrice has come back up to revisit an old resistance ceiling which it has touched around three times in the past. Tuesday saw the price open right at this level, only to trigger a fast sell-off on a huge spike in volume. The size of this daily candle completely engulfed the previous day’s entire trading range. In VPA terms, a bearish engulfing pattern on high effort is a clear signal of structural weakness. I am always more conservative when highlighting shorting opportunities because the risks involved can increase massively. If you are going to play the short side, I highly recommend using guaranteed stops. Could this massive volume spike be indicative of further falls ahead? The line in the sand is very clearly defined at that old ceiling.
