You can only set up the inputs to move SL to break even when
a trade is 20 pips in profit, but currently there’s no
option to close the trade at the same time.
To do that, in Set Break Even Rule choose
At open price, and in Pips Trigger
From Open Price enter 20.0. You can also set
pips offset, meaning how many pips from the open price in
profit direction the SL will be set.
