When I submit a main order with a Takeprofit, each time the main order is partially filled, will the TP order adjust its amount automatically ? Idem for the StopLoss ?

Thank you,

Hi,
if you are using a DEMO account, could you please send us order id numbers?

It was just a question to know how to write my strategy, because it's not easy to check how the partial fills are working on backtests.
Up to now, I have no problems and not so much partial fills, but it might happen when the amounts will grow; that's why I would like to know what the behavior of the Takeprofit orders is intended to be: if their amounts will follow the amount of the partially filled main order or not.
And, if the main order is a Limit Order, if the amount of the TakeProfit Order will be automatically updated each time a subsequent partial fill of the main order occurs.

Thank you for your attention,
Michel

Yes, it will follow main order. The amount of all partly filled orders could get by a IOrder.getAmount() function. It's a same for the Limit orders.
In JForex, if an order is partly filled, then its IOrder.State is set to FILLED. Use a function IOrder.getAmount() to know how far the order has been filled. Each time an partial fill happens the message IMessage.ORDER_CHANGED_OK is sent.
