Study symbol. Number of rules with study symbols (study alerts) is limited (10 by default).
Note: Study symbols are only allowed in function expressions (see Expression.arguments).
Type: string
Description: Symbol pattern to resolve into a contract and use its market data. Symbol must be specified in CQG dialect. It is allowed to specify a relative symbol (e.g., “EP”) so that the rule will switch to a new most active contract on a rollover event. If there is no need in contract switching a full contract symbol needs to be specified (e.g. metadata_2.ContractMetadata.cqg_contract_symbol). For option contracts only full symbols are allowed. The rule becomes disabled (see RuleDefinition.enabled field) when the market data on the current contract is no longer available.
Required: yes.
