Скопировать индикатор написанный на mql4 в Ninjatrader.

Здравствуйте, нужно сделать, индикатор для терминала Ninjatrader, такой как приложен mq4.

#property strict
#property indicator_separate_window
#property indicator_buffers 5
#property indicator_plots   5
#property indicator_minimum 0
#property indicator_maximum 100
