The evaluation metric is the **Cumulated Profit and Loss**.
Based on the spread forecast (Imbalances - DA), the strategy is as follows:
- If spread >= 0, buy 50 MW on the Day-Ahead market (long position)
- If spread < 0, sell 50 MW on the Day-Ahead market (short position)
- If the Imbalances price is valued at more than 1000€, do not take a position (considered too risky)

Then we calculate the cumulative profits and losses over the entire period, obtaining a metric in €.
