Sadly yes. Spreads are (atm) wider than an OTC provider AND they require approx 4times the margin that their OTC providers do.
The exchange has DPM's (Designated Price Makers) - institutions that have some good incentives to provide a liquid market. That said, the following must be noted:
1. These products were only launched in mid November, and,
2. There were previously problems for the DPM's to enter prices onto the system, and,
3. The ASX will be taking their CFD show on the road again in February.
IMHO, these negatives can be overcome when more liquidity comes to the market (eg a 2pt spread (which would match the OTC providers) on the ASX200 index). This being the case, I would happily trade with them even considering the increased margin requirement for the reasons of trading DMA through an exchange and all the benefits that provides....
Guess it's a case of wait and see I suppose, but for the time being, one thing's for sure - the DPM's aren't fulfilling their role as anticipated at this moment in time....
