If you close half of lot then the rest is another 50% of closed lot.
Please specify your question.

Your question is still not clear as can be seen in the replies above which seemed to have missed the point, but I will give it a try. If I miss the point, well that makes 3 of us.

For simplicity I am going to assume you want to close the trade in 2 parts. 3 or more parts is possible, but I don't want to complicate my answer. The key to partial closing is knowing what the original size of the trade position was. You need to keep track of this in your program. There are several ways to do this, you can decide how you would like to do this. If you...

1) You can compare initial lot with actual lot size of orders.
If actual lot size is less than initial lot then partial close was applied so you need to skip PartialClose function.

2) It would be better for you to change the conception.
Just open 2,3,4,... orders with different targets.
