Module instrument 

Instrument directory mapping.

Functions

apply_trade_lot_size

The lot for trading, when GetAssetParams gives one: trade_lot_size above 0 replaces the lot size of GetAsset (lot_size and min_qty). 0 or less means “no value” and params stays as it is.

availability_at

Availability from the schedule: inside a non-closed session -> open, otherwise closed.

kind_from_type

Finam’s type strings are not enumerated in the docs; matched by substring.

map_asset

A directory entry (Assets, AllAssets) -> core instrument.

map_get_asset

A GetAsset answer -> core instrument. symbol is the SYMBOL@MIC that was asked for.

map_schedule

A Schedule answer -> core schedule for the range from..to.

map_trading_params

Price step = min_step / 10^decimals. Finam does not give the money value of a step, so price_step_value equals price_step (right for stocks, not for futures). min_qty is one lot because orders are in pieces and sized in whole lots.

session_kind

Session type heuristics: the docs do not list the type values.
