Hello.
My strategy works with market depth data. I am getting it by JForex API via IStrategy.onTick(). Sometimes strategy loads input data with 2 values only after application starting. And market depth panel on show only 2 values too. When I select other instrument on client data start come complete. There are 10 values for bid and 10 value for ask. But no every time onTick. Sometimes 8 asks and 10 bids. Earlier 5 ask and 5 bids levels for example.

I read javadoc and subscribed to instrument via setSubscribedInstruments().

I need to know precision count of levels or rules that change it. This is important for my strategy.

As you can observe the count ranges from 1 to 10, depending on market situation and data available on the server side. Mind that for all historical data the market depth size is 1.
