is there a way to combine a limit order with a trailing stop? i.e. if the limit is reached, the trailing stop discards itself.
Unfortunately not.
But this is a very frequently posed feature request.
(Typically the request is to combine a limit and a fixed stop)
This would be very helpful indeed, since it supports the standard situation when you try to "get into a position".
My guess is that implementing such a feature will create a challenge for both the internal data representation and the visualisation in the GUI
@Bitfinex team: are there any plans or have you considered such a feature?
