historical BID ASK data where to buy?

[twinx]

Hello,

where do you get historical intraday BID ASK data for backtesting?
I can have some over the API from IB, but no expired contracts!

Until now i found on the web, only tick or other intraday data which are only prices data which were traded. But i want the BID ASK quotes (1 minutes, 2, or 5 minutes) would be nice.

Look for:
CME® E-mini® EQUITIES indices
European EQUITIES indices
Where do you get historical intraday BID ASK data?

PS: do you backtest only with traded prices?

This is the link to Eurex exchange where you can get their tick data

Be very carefull if buying it from vendors. You know garbage in, garbage out.

You misunderstood. I dont want normal tickdata!

BID ASK data like this:

BID data example:
Date		Time		BIDopen	BIDhigh	BIDlow	BIDclose
01.02.2006	15:45:00	4958.50	4958.50	4958.50	4958.50

ASK data example:
Date		Time		ASKopen	ASKhigh	ASKlow	ASKclose
01.02.2006	15:46:00	4960.50	4960.50	4959.00	4959.00
