Abstract :
In this paper, we investigated the copper futures in SHFE of multiple time scales. Using Multifractal Detrended Fluctuation Analysis (MF-DFA) and Multifractal Spectrum, we found that multifractal spectrums of different time scales (τ=1, τ=5, τ=22) have the similar shape. Time scale just affects the width (ΔDC) and the fractal dimensions (Δf) of the spectrums. With the time scales, the degree of the multifractal also strengthens. Hurst exponent implies that there exists long-term memory in the copper futures market, which degree also strengthens as the time scale increases.
