How is the bid-ask computed?

For a certain combination of specifications in the attributes that define a carbon project (standard, project activity, geography, and contributions to SDGs), the AI engine infers the full probability distribution of prices from the market.

As such, bid-ask spread is simply a certain number of standard deviations from the mean of the distribution. That number of standard deviations is also inferred from market data and updated as new market data comes along.
