Module schedule 

Schedule mapping.

GET /trading-schedule/daily-schedule (docs, checked 2026-10-19) takes classCode AND ticker (both required) and answers isWorkDay and dailySchedule[], where startDate / endDate are TIMES OF DAY ("14:30:00", the doc example), tradingSessionType is a Russian name (Торговый период, Вечерняя торговая сессия, Аукцион открытия, Аукцион закрытия, Технический перерыв QUIK, Не рабочее время/Выходной/Праздник) and tradingSessionStatus is OPEN or CLOSE.

The answer is for ONE day (today), so the intervals are put on the day of range.from. The time zone of the times is not stated: they are read as Moscow time (UTC+3), which is an assumption. A full datetime (the form older samples had) is read as it is.
