after two years waiting and some sixty% down ,do i take the paltry sum left and put it into my coh or hope there might be some screaming diamonds about to show?

Might be worth waiting for the test results from ABN 021 before you decide. Admittedly, if the test results are bad, then the sp will reflect this, but if good, then you will probably see a good bounce in the chart.
I don't hold this stock but why take a loss if you don't need to yet.

Manythanks,HARRYCAT now I understand stoploss! If thereare others in GRN please come out from under the diamonds!!and tell me what agood ABN021 should look like.
