I'm currently short on this.
For reference purposes, these are my own thoughts on this, a pull back to 97.90 / 98.78 area - (61.80% / 78.6%) is a good area to be short, or even at current price, although i think we may get back to the 98.30 area.
Targets are way down at the 91- zone.
Stop would be above the 99.88 plus an allowance for the spread.
