Hi hua,
Happy new year!
Please try this code (I didn't test it because it's Saturday)
PHP Code:

//-------------ang_Amp_ZZ---------------
#property indicator_chart_window
#property indicator_buffers 3
#property indicator_color1 LemonChiffon
#property indicator_color2 LemonChiffon
#property indicator_color3 Blue
//--------------------------------
