Correlation measures the relationship between two items and shows how prices changes in one instrument affect the price of the other.
The object is to see how dependent one instrument is on the price of the other.
The result of the correlation study is a single number that is the historical correlation for the entire compared history of both symbols.

For example, if doing a correlation on weather and a specific crop, such as wheat or corn, you will see a high positive correlation, indicating the weather has an effect on crop prices.

The correlation result will be measured in a range of +1.0 to -1.0.  The closer the result is to + or – 1.0 the greater the relationship is between the two instruments.

A correlation of +1 means changes in the price of one instrument will be identical.  For example, the price of crude will affect the price of heating oil.  If crude goes up, it’s likely that the price of heating oil will also go up.

A correlation of -1 means changes in the price of one instrument will affect the price of the other, but in the opposite direction.  For example, you would see a negative correlation between the value of the dollar and the price of gold.  If the dollar value is up, the cost of gold is down.  If the dollar value is down, the cost of gold will rise.
