  1. Check the price from a Chainlink aggregator.

  2. If the price is below or equal to zero, call dForce backup price oracle, which is currently maintained by the dForce team.

  3. For prices Chainlink not provided, price is posted by service maintained by dForce team, currently, only DF.

  4. In the future, dForce governance will manage the selection of price sources.
