EurostatIndustrySurvey(line: str)

Bases: BaseData

The European Commission's monthly industry survey for a single European economy: what manufacturers report about their order books, their stocks, and what they expect to produce, charge and employ over the coming months.

These are expectations, not measurements, which is why they arrive before the month they describe has finished, months ahead of the hard industrial production figures they anticipate.

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`

industrial_confidence

industrial_confidence: Optional[float]

Industrial confidence indicator: the composite of order books, stocks of finished products and production expectations. This is the headline of the survey and also the data point's Value.

order_books

order_books: Optional[float]

How manufacturers assess the current level of their order books, the survey's read on demand already on the books rather than expected.

export_order_books

export_order_books: Optional[float]

How manufacturers assess the current level of their export order books. Against domestic order books it separates external demand from internal, which is what makes an export-driven economy sensitive to the global cycle.

stocks_of_finished_products

stocks_of_finished_products: Optional[float]

How manufacturers assess their current stocks of finished products. It reads inverted: stocks piling up mean demand is falling short of output, so a rising balance is the weaker signal.

production_expectation

production_expectation: Optional[float]

What manufacturers expect production to do over the next three months, the most direct lead on the industrial production index.

selling_price_expectation

selling_price_expectation: Optional[float]

What manufacturers expect their own selling prices to do over the next three months. This is pipeline inflation at its source, ahead of both producer and consumer prices.

employment_expectation

employment_expectation: Optional[float]

What manufacturers expect employment to do over the next three months.

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.

ALL_RESOLUTIONS

ALL_RESOLUTIONS: List[Resolution] = ...

A list of all Resolution

This Field is protected.

DAILY_RESOLUTION

DAILY_RESOLUTION: List[Resolution] = ...

A list of Resolution.DAILY

This Field is protected.

MINUTE_RESOLUTION

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.

OPTION_RESOLUTIONS

OPTION_RESOLUTIONS: List[Resolution] = ...

A list of resolutions support by Options

This Field is protected.

data_time_zone

data_time_zone() -> Any

Gets the time zone the data is published in.

Returns:

Type	Description
`Any`	The data time zone.

default_resolution

default_resolution() -> Resolution

Gets the default resolution for this data.

Returns:

get_source

get_source(

is_sparse_data

is_sparse_data() -> bool

Indicates whether the data is sparse. One file per economy means LEAN will look for files that legitimately do not exist for economies outside the survey.

Returns:

Type	Description
`bool`	True.

reader

reader(
