# Prices This section manages the prices for each fluid in the ecolyo application. ## Rules - The next price to create is automatically pre-selected by default - Only the 2 last prices plus the one to create are editable, the others are just searchable - Each fluid has its own date frequency : - Electricity : one new price every 6 month (February and August) - Water : one new price every year - Gas : one new price every month - When user creates a new price, the previous price's endDate is set to the new startDate minus 1 minute, so every prices keeps following in time.
