Name	Environment Variable	Description
`otp.config.tz`	`OTP_DEFAULT_TZ`	Default timezone used for running queries and creating databases, e.g. with `otp.run`. Default value is the local timezone of your machine.
`otp.config.context`	`OTP_CONTEXT`	Default context used for running queries, e.g. with `otp.run`.
`otp.config.default_start_time`	`OTP_DEFAULT_START_TIME`	Default start time used for running queries, e.g. with `otp.run`.
`otp.config.default_end_time`	`OTP_DEFAULT_END_TIME`	Default end time used for running queries, e.g. with `otp.run`.
`otp.config.default_db`	`OTP_DEFAULT_DB`	Default database name used for running queries, e.g. with `otp.run`.
`otp.config.default_symbol`	`OTP_DEFAULT_SYMBOL`	Default symbol name used for running queries, e.g. with `otp.run`.
`otp.config.default_symbology`	`OTP_DEFAULT_SYMBOLOGY`	Default database symbology.
`otp.config.default_concurrency`	`OTP_DEFAULT_CONCURRENCY`	Default concurrency level used for running queries, e.g. with `otp.run`. Default value is the number of cores/threads on your machine.
`otp.config.default_batch_size`	`OTP_DEFAULT_BATCH_SIZE`	Default batch size used for running queries, e.g. with `otp.run`. Batch size is the maximum number of symbols that are processed at once. The value of 0 means unlimited – works faster for simple queries, but may consume too much memory for complex queries.
`otp.config.default_license_dir`	`OTP_DEFAULT_LICENSE_DIR`	Default path for license directory. Needed for user to be allowed to use OneTick API. Default value is system-dependent: /license for Linux systems and C:/OMD/client_data/config/license_repository for Windows systems.
`otp.config.default_license_file`	`OTP_DEFAULT_LICENSE_FILE`	Default path for license file. Needed for user to be allowed to use OneTick API. Default value is system-dependent: /license/license.dat for Linux systems and C:/OMD/client_data/config/license.dat for Windows systems.
`otp.config.default_fault_tolerance`	`OTP_DEFAULT_FAULT_TOLERANCE`	Default value for USE_FT query property.
`otp.config.default_auth_username`	`OTP_DEFAULT_AUTH_USERNAME`	Default username used for authentication.
`otp.config.default_password`	`OTP_DEFAULT_PASSWORD`	Default password used for authentication.
`otp.config.max_expected_ticks_per_symbol`	`OTP_MAX_EXPECTED_TICKS_PER_SYMBOL`	Expected maximum number of ticks per symbol (used for performance optimizations).
`otp.config.show_stack_info`	`OTP_SHOW_STACK_INFO`	Show stack info (filename and line or stack trace) in OneTick exceptions.
`otp.config.log_symbol`	`OTP_LOG_SYMBOL`	Log currently executed symbol. Note, this only works with unbound symbols. Note, in this case `otp.run` does not produce the output so it should be used only for debugging purposes.
`otp.config.ignore_ticks_in_unentitled_time_range`	`OTP_IGNORE_TICKS_IN_UNENTITLED_TIME_RANGE`	Default value for IGNORE_TICKS_IN_UNENTITLED_TIME_RANGE query property.
`otp.config.main_query_generated_filename`	`OTP_MAIN_QUERY_GENERATED_FILENAME`	The name of the .otq file with generated main query executed by otp.run.
`otp.config.logging`	`OTP_LOGGING`	The logging level string or path to the file with configuration. Check the documentation of python logging module for the configuration formats. JSON format (in the file with .json suffix) and python configparser formats are supported.
`otp.config.otq_debug_mode`	`OTP_OTQ_DEBUG_MODE`	Enable .otq files debug mode. If set to True, onetick.py will keep all generated otq files and log their paths to the console.
`otp.config.allow_lowercase_in_saved_fields`	`None`	Allow using lower case characters in field names that are being stored in Onetick databases. If set to False, onetick.py would not allow saving fields with lower case characters to a database.
`otp.config.default_db_symbol`		Default symbol with database. Defined with `default_db` and `default_symbol` as string default_db::default_symbol.
`otp.config.default_date`		Default date. Defined as a date part of `default_start_time`.
