SHI回测 (SHI Backtesting)

Hi to all.
This morning I tryed some backtest taking data from metatrader.
After that, I have compiled an Excel file and I've analyzed the data inserting the close point I took looking the SHI SilverTrendSig.
I notice that, all the transaction, BUY or SELL, are profitable; as you can see in the enclosed PDF, some ot these only a few pips, but other also greater than 100 pips.
I would ask if someone can confirm me this indicator and his good respose to the market. I use that in EUR/USD with 2 pip spread.
I would like to know how to create an automated trading system based on this idea. Or someone has already created something similar.
Thank you all for your help.
Bye
Marco
