JBookTrader, Bid+Ask prices

[eyal8698]

Hi,

I see that in JBookTrader the bid and ask prices (Forex) are unified in one member called price.

Is that how IB send it? cause in their desktop GUI I see both quotes.

How can I differ in real-time between the two quotes?

Thanks.

The IB API sends both bids and asks, but JBookTrader records only the midprice, which is (bidPrice + askPrice) / 2.

JBookTrader is meant to auto-trade very liquid instruments for which the bid/ask spread is nearly always constant.
