The next setup is the "golden cross", if GBA re-listed it would be the opportune time to buy at the next Golden Cross.
Remember what Patterns said:
As BPH is the main driver for PEP-11 entities (for example I think ASX:BUY just copies BPH price movements) then unlistedGBA would likely have a moving relative value to BPH.

The golden cross basically shows there is increasing activity recently, compared to previously. Then, once there is blue sky breakout, all technicals most likely converge to show positive signals for the future.
