Historical Ask/Bid Prices

[Rollins]

Hi,

am I right when I assume that it is impossible to get historical ask/bid prices?
As far as I know OnMarketData only gives access to the current ask/bid, except for market replay, I guess utilizing it in a strategy wouldn't produce a different behavior.
Since no data export file format I know of provides the bid/ask price, storing the data in real time in an external file might be my only option.

Thanks

Correct, this is on our list for NT7 though.
