Multi Targets/Stops with IG broker in the US? ProRealTime platform

[Monique]

Has anyone tried to use the Multi Targets/Stops option with IG broker in the US?
I've just tried and with no success, because of so called FIFO rule (I was told).

Here is an example.
Let's say
I have only ONE position going in the same direction (e.g Long) , with the following
inputs:
Qty           Target                Stop
70%           15 pips             10 pips
20%           20 pips             10 pips
10%           25 pips             10 pips

The total Qty (quantity) is
100%, so it is just ONE position, but with different Targets and the same Stop.
Only ONE order from the above example was filled (the very first one with 70%) and 2 other were rejected.
I have tried with different Targets and different Stops numbers; still no success.  Each time only one order is accepted, and the rest were rejected.

Have anyone tried to use that option, here in the US or maybe you know a work around it?

Thanks for your input.
