Many observables which are used as a signature of collective effects in heavy-ion collisions when measured in high multiplicity pp and pA interactions reveal a very similar behaviour. We present first measurements of different order flow coefficients and their magnitude correlations using the Symmetric Cumulants for data collected by ALICE during the LHC Run 2 operation. The data sample includes pp collisions at $\sqrt{s}$ = 13 TeV, p-Pb at $\sqrt{s_{NN}}$ = 5.02 TeV, Xe-Xe at $\sqrt{s_{NN}}$ = 5.44 TeV and Pb-Pb collisions at $\sqrt{s_{NN}}$ = 5.02 TeV. Such a broad spectrum of colliding systems with different energies and wide range of multiplicity allow for detailed investigation of their collision dynamics. The measurements are based on the newly developed pseudorapidity-subevent technique, which was proven to be particularly important for studies in small systems. The results are compared to various theoretical models providing an important insight into initial conditions and the nature of collective phenomena in different collision systems.
