Thanks mwatts,
The last placement there were approx 15-20mil traded from 5 to 6c. Once they hit 6c they were dumped all the way back to 4.6 and they've been going down ever since. I expect them ranging to 4.5 at max before the dump again.
It's very tempting to have a go again but I got caught at 5.5 so I've finally learned my lesson, 400 times burnt never again! (I'm a slow learner :-) )
Cheers
