Hello! I have a few questions regarding place bid / offer (IEngine.OrderCommand.PLACE_BID, IEngine.OrderCommand.PLACE_OFFER):

Context is as follows:

I'd like to mimic an immediate-or-cancel style of order. For the purpose I'd place a bid / offer onto the current ask / bid or better, respectively, with a small time-to-live (goot-till-time) interval, say 1000 millis.

-Is there a limit as to how small (>0) this interval can be?


-In this case the method submitOrder(label, instrument, orderCommand, amount, price, slippage, stopLossPrice, takeProfitPrice, goodTillTime) has to be used at least. What, in this context, is the meaning of the slippage parameter? — I assume it has to be set to Double.NaN?



Or do you have another suggestion, as to how to implement an ioc-style order (i.e. if the order cannot be executed at preferred price immediately, it is canceled immediately), I cannot see how this can be done directly with the implemented submitOrder(..) methods and order command types.

Regards

No there is no such limit, note that if you set the goodTillTime parameter to 0, then you will remove the "Good till"condition.
Slippage is int (it is measured in pips) and it does not get applied for bids and offers. Thus, you can use any arbitrary value >=0.
