Pre-open bid/ask data for ASX stocks

[torch]

Is there any way to get accurate pre market bid / ask data for ASX stocks?

I use eSignal for my data feed, and prior to the open, all ASX stocks show a crossed bid / ask, ie; 50.00 bid, 30.00 ask. A second or so before the open a true bid/ask will appear, then trading starts.

Clearly the crossed market is inaccurate, and somebody is seeing data that allows an accurate view of where a stock will open. Any suggestions?

Thank you.

No, it's not inaccurate. It is the pre-market open auction.

Either eSignal or your trading platform should also give you the indicative open price which is where the ASX algorithm will determine the open price based on the price/volume crossover that you're observing.

eSignal has not been helpful at all in determining an opening indication. Can you suggest a data feed that provides this?

Comsec will, as will etrade (ANZ) and Westpac's trading platform

BourseData have a professional feed that transmits the ASX pre-open session from 07:00 am through 10:00 am which gives you the crossover bids and asks plus the resulting "match price" or anticipated open price, which constantly changes as orders are entered.
