duza,
Since GMM is likely to be removed from ASX listing if totally taken over by GXY (hopefully soon), the symmetrical triangle (see my version below, plot 1) predicting .98 to 1.02 for GMM could be interpreted as those values divided by 1.65 ie, .59 to .62 for gxy.
The equivalent flag and pole analysis for GXY (FLAG 2 on plot 2 below) is ragged ended but could still be interpreted to suggest a GXY value of around .65, similar to the prediction from GMM.
I have avoided posting this flag before because the GXY SP is all about FA at the moment - GMM takeover completion, SdeV announcement.
