What you are doing is going to lead you to a dead-end CroMag.

You cant get 'raw ASX data' from that period. Third-party platform providers like IRESS provide broker trade details but only after T+2. They do not have data extending to the period you are asking about. Even if you did get the broker values its not going to reveal anything to you.

Additionally link market services is a registry in its own right, so what registry details are you looking for? history of what? You cant get the registered holder details for specific trade/s at any given date. This is a privacy breach.

The registered holder list at a given time (entire or T20) can be retrieved for a fee. But again this wont reveal anything to you.
