We believe that traders provide an important and valuable service to energy markets. We do constant and fast-paced analysis on the current state of the electricity grid and provide all actors crucial information through price signals. We act as intermediaries and decision makers who take risks that other actors would like to avoid. We take on this responsibility with decisive caution. We reduce shortages and oversupply by looking ahead. We need volatility to act, however we reduce volatility overall. In order to trade successfully we need fair and open markets. In order to trade fairly with the market we believe in sharing information, failures and victories and yes: the occassional trash talk.
