Help CenterLMax offers Netting account, it means that trades are not segregated, the trades are sum up and you cannot have a long and short position at the same time. This makes impossible to copy the SL and TP to/from a LMax account in a relevant way.
However, please note that it should not be an issue, as soon as a Limit, Stop, SL or TP is triggered, it will send a relevant market order. You will always have the same position, but the way it is triggered is different.
