YEM provides a schedule with optimal fixing dates created on the basis of your contractual parameters. Yem optimisation gives you a dynamic view of market prices consistent with your chosen risk appetite.
By choosing a high, medium or low risk strategy, you tell the instrument whether you want to take more or less risk.
 The strategies correspond to YEM algorithms based in particular on Ref-E economic intelligence and their forecasts of energy market prices.
YEM’s fixing advice covers 100% of your gas or electricity quantities for the fixing periods of your contracts.
 YEM advises you on fixing transactions at least 2 months before the start of each fixing period of your contracts. For example, we do not advise you to fix the January-March 2021 period later than 1 November 2020. Risking fixing at the last minute is too risky a strategy that YEM does not consider or recommend.
