Here is another Exco Chart for those of you who are interested.
This one is a longer term chart that shows the trend channel that Exco have been in since August last year (with a few slight adjustments along the way, I had it too steep early on, I was a bit too optimistic)
From this chart you can see when the Share Price is over bought and when it is over sold.
I marked the selloff's along the way, for interest's sake.
there are also a couple of other comments as well.
