A Simple Gold Trading System (2)

What was the result of this system?

Backtests of the system since 1971 show that it has earned investors an income of 16.8% a year when gold was bought (its price was above its 10-month moving average) and income of 2.9% when it was sold (the price was below the 10-month moving average).
For comparison, following the simple buy-and-go strategy for gold for the period under review has yielded an average annual return for investors of 8%.
In short, investors were definitely supposed to be in gold when they had a "purchases" signal.
Summarized, the system results look like this:
Between 2001 and 2012, the system has given frequent "buy" signals.
Between 2012 and 2015 dominated "sell" signals.
In 2016, the system gave signals for purchases in the first half of the year and a signal for sale from mid-October.
