ohh that guy Martin Pring, not sure about that module thing but try adding an expert adviser to any chart "Martin pring - long term momentum system" you will notice that its password protected so you can't see the formula hmmm, now zoom out on that chart & make a note of when the signals are. Now add the "Equis-MACD" you will see that the buy/sell signals are in exactually the same place, your probly better off ignoring anything Pring has made.
