    /// This macro generates a test module containing tests for:
    /// 1. Creation from sample data.
    /// 2. Correctness of default values.
    /// 3. Serialization and deserialization integrity.
    ///
    /// # Arguments
    ///
    /// * `$test_module_name`: The name of the module to generate for the tests.
    /// * `$model_type`: The type of the struct to be tested (e.g., `RawTrade`).
    /// * `$sample_data_fn`: An expression that returns a valid instance of the model type.
    /// * `$default_checks`: A closure that takes a reference to a default instance
    ///   and performs assertions on its fields.
