Walk Forward Analysis, a real case on mini-silver YI

The WFA (Walk-Forward Analysis) is an advanced optimization to calculate best parameters and inputs combinations in the trading systems. Each system has some inputs to optimize, and with the optimization you can evaluate the historical results. A way to find best combinations is the WFA. For example, a trading system could to work fine, in a specific market, with a moving average equal to 20. But it could to work fine with a moving average equal to 30 in another market. If you try to test, the WFA helps us to determine best inputs combinations.
What is exactly the WFA? The "secret" is in time interval. Usually in the optimization we use the historical series price as unique block, but with a WFA you need to divide the historical series price in several segments. This segments are called "in-sample" and "out-of-sample". Tomorrow we have to see what is the difference between those segments.

At the end of this article you can find the Walk-Forward Analysis on mini-silver (YI).
