EurostatServicesSurvey()

EurostatServicesSurvey(line: str)

Bases: BaseData

The European Commission's monthly services survey for a single European economy: what service firms report about their business situation and demand, and what they expect of demand, employment and prices over the coming months.

These are expectations, not measurements, which is why they arrive before the month they describe has finished. Services are the largest share of euro area output, and services inflation is the component the European Central Bank watches most closely because it is the slowest to come down.

Every reading is a balance: the share of firms answering positively minus the share answering negatively, so it runs from -100 to +100 and zero means the two camps are the same size.

One file per economy, one row per month. Subscribe with a geo code, e.g. AddData(Eurostat.Economies.EuroArea) for the euro area or (Eurostat.Economies.Germany) for Germany.

Signature descriptions:

Creates a new default instance.
Creates a new instance from a CSV line produced by the data processor.

Parameters:

Name	Type	Description	Default
`line`	`Optional[str]`	Line of the source CSV: month, publication date, then one column per question	`None`

services_confidence

services_confidence: Optional[float]

Services confidence indicator: the composite of the business situation, recent demand and expected demand. This is the headline of the survey and also the data point's Value.

business_situation

business_situation: Optional[float]

How the business situation developed over the past three months.

demand_development

demand_development: Optional[float]

How demand developed over the past three months.

demand_expectation

demand_expectation: Optional[float]

What service firms expect demand to do over the next three months. Against recent demand it shows whether the sector expects the current pace to hold.

employment_expectation

employment_expectation: Optional[float]

What service firms expect employment to do over the next three months. Services carry most euro area employment, so this is the survey family's broadest labour signal.

price_expectation

price_expectation: Optional[float]

What service firms expect their prices to do over the next three months, an early read on the services inflation the European Central Bank follows most closely.

end_time

end_time: datetime

The date the survey round was published, which is when LEAN makes the data point available.

symbol

symbol: Symbol

Symbol representation for underlying Security

data_type

data_type: MarketDataType

Market Data Type of this data - does it come in individual price packets or is it grouped into OHLC.

time

time: datetime

Current time marker of this data packet.

value

value: float

Value representation of this data packet. All data requires a representative value for this moment in time. For streams of data this is the price now, for OHLC packets this is the closing price.

price

price: float

As this is a backtesting platform we'll provide an alias of value as price.

DAILY_RESOLUTION: List[Resolution] = ...

A list of Resolution.DAILY

This Field is protected.

MINUTE_RESOLUTION: List[Resolution] = ...

A list of Resolution.MINUTE

This Field is protected.

HIGH_RESOLUTION

HIGH_RESOLUTION: List[Resolution] = ...

A list of high Resolution, including minute, second, and tick.

This Field is protected.

A list of resolutions support by Options

This Field is protected.
