Function parse_cfm_position_status_report 

pub fn parse_cfm_position_status_report(
    position: &CfmPosition,
    instrument: &InstrumentAny,
    account_id: AccountId,
    ts_init: UnixNanos,
) -> Result<PositionStatusReport>

Parses a single CFM position into a Nautilus [PositionStatusReport].

The position’s quantity is scaled by contract_size (expressed in the instrument’s size precision). Callers are expected to supply the matching instrument so precision lines up with the venue’s reported number of contracts.

Errors

Returns an error when the quantity or average entry price cannot be represented with the instrument’s precision.
