Attached image shows a partially filled PLACE_OFFER order using the JForex platform, for 3.000 thousand. The order is partially filled with amounts which can be seen on the message log totalling 2.352 thousand. 3 separate partial fill events occurred and then, because the remainder was <1000 the order for the remainder was Cancelled.

This makes it very difficult to manage PLACE_OFFER or PLACE_BID orders because they are not guaranteed to fill completely, even if the market passes well through the order price, due to cancellation of the order for the <1000 remainder. At any point where the remainder is <1000 the remainder outstanding order will be Cancelled.

However, if I have an order which is filled <1000, I am able to Close it through the JForex platform, even though I am not able to issue any order for Amount < 1000. In a Strategy module, additional logic would be required to choose Close, versus Cancellation of an order with requestedAmount <1000.

Is the API also restricted so that order submission <1000 is disallowed? It appears the only way to get FLAT is to Close the order if amount <1000 and I assume both JForex platform and the API would both behave in this same manner?

Is there any way to guarantee that the PLACE_OFFER or PLACE_BID will be able to be completely filled, in the case of multiple partial fills?

ARE THERE ANY PLANS TO DEAL WITH SUB-MICRO LOT FILL QUANTITIES, OR REMAINDERS?
For example, Sub-Micro lot <1000 fill quantities could be disallowed, and/or a remainder <1000 could be permitted as a lot size on an Order.
