Data driven test procedure for detection of change is introduced and its properties are studied. The new solution is max-type
statistic related to data-driven rank tests for two-sample subproblems. Simulations show that the new test possesses high
and stable power. The test is consistent at essentially any alternative. Asymptotic null distribution of the test is derived.
