Nickel is one of the most important materials of stainless steel, which is massively used in diverse industries such as automobiles, remote communication, engineering construction, chemical engineering, food processing, aviation and aerospace industry.
The price of nickel fluctuates wildly between US$ 13,000 to US$ 52,300 per ton. One of the key factors to control the manufacturing cost of stainless steel is to precisely predict the price of nickel.
Records such as multiple futures trading prices, industry articles and news related to the topic are provided to the participants, hoping that these data can help grasping the key of Nickel price forecasting.

The system will process evaluations in batches regularly to calculate the scores. Evaluations are conducted by calculating the Mean absolute percentage error, MAPE, of the predictive and actual result.
The formula is as follows.
$$ MAPE = \frac{100}{n} \; {\sum_{i=1}^{n}} \; { \biggr\lvert \frac{ y_i - \hat{y}_i }{y_i} \biggr\rvert } $$
