  The nonlinear Schr{\"o}dinger equation with derivative cubic nonlinearity
admits a family of solitons, which are orbitally stable in the energy space. In
this work, we prove the orbital stability of multi-solitons configurations in
the energy space, under suitable assumptions on the speeds and frequencies of
the composing solitons. The main ingredients of the proof are modulation
theory, energy coercivity and monotonicity properties.
