Manual Pricing for Ratio Based Contracts

Ratio based contracts can only be priced manually, not automatically. Automatic fixing is not feasible for commodities with a ratio because the quantities have an unpredictable nature and would need to be updated each time you do a fixing and deviate from the number of lots predicted based on the market ratio.

Therefore, a hedge requirements with purpose Fixing will not be generated at contract creation. Only the hedge requirement with purpose Hedging will be generated. No updates takes place from Fixing to Hedging, because the Fixing type of hedge requirement is not used for Ratios.

The number of lots to create depends on what you enter on the Risk tab.
