The search for cosmic ray anisotropy has been performed using particles collected by the Alpha Magnetic Spectrometer after the first five years of operation. The positron to electron ratio is consistent with isotropy at all energies and angular scales. The limit on the dipole anisotropy at the 95% confidence level for energies above 16GeV is δ<0.020 for positrons and δ<0.006 for electrons. In the case of high rigidity protons the upper limit in the rigidity range from 80 to 1800GV is δ<0.003. No indication of seasonal excess is observed for all particle species within the present statistics. Comments:    XXV ECRS 2016 Proceedings – eConf C16-09-04.3
