Data Retrieval#

OneTick is a time series database meaning that each record has a timestamp and timestamps of consecutive records are non-decreasing. Multiple time series are stored in OneTick. An individual time series is identified by the symbol (aka ticker, financial instrument, security), tick type (i.e., the type of data such as trades or quotes), and the name of the database where the time series is stored.

import onetick.py as otp

s = otp.dt(2024, 2, 1, 9, 30)
e = otp.dt(2024, 2, 1, 9, 30, 1)

# we can retrieve the list of databases available on the server
# (note that not all databases may be readable by your user,
#  but the _SAMPLE databases should be)
dbs = otp.databases()
list(db for db in dbs if db.endswith('_SAMPLE'))

['CA_COMP_SAMPLE',
 'CME_SAMPLE',
 'EUREX_SAMPLE',
 'EU_COMP_SAMPLE',
 'ICE_EU_COM_SAMPLE',
 'ICE_US_SAMPLE',
 'LSE_SAMPLE',
 'TDI_FUT_SAMPLE',
 'US_COMP_SAMPLE']

# the list of dates with data for the db
dbs['US_COMP_SAMPLE'].dates()[-5:]

[datetime.date(2024, 3, 22),
 datetime.date(2024, 3, 25),
 datetime.date(2024, 3, 26),
 datetime.date(2024, 3, 27),
 datetime.date(2024, 3, 28)]

# or just the last day with data
dbs['US_COMP_SAMPLE'].last_date

datetime.date(2024, 3, 28)

# and the list of tick types
dbs['US_COMP_SAMPLE'].tick_types()

['DAY', 'IND', 'LULD', 'MKT', 'NBBO', 'QTE', 'STAT', 'TRD']

We can now retrieve symbols traded in a given time range. (In many financial markets, there are properties that remain constant throughout the trading day. Examples include the name of a financial instrument and the set of instruments traded).

symbols = otp.Symbols('US_COMP_SAMPLE')
otp.run(symbols, start=otp.dt(2024, 2, 1), end=otp.dt(2024, 2, 2))

We used the otp.run method above, which executed a query that retrieved the list of symbols.

The start and end timestamps were specified with onetick-py’s datetime class otp.dt.

Now that we have database names, tick types, and symbols, we are ready to query a time series.

Note that we specified the start and end of the time series to retrieve the corresponding interval.

Warning

In otp.DataSource default value of the parameter schema_policy enables automatic deduction of the data schema.

It works fine for simple cases like using onetick-py in Jupyter notebooks, but it is highly not recommended for production code.

For details see Schema deduction mechanism.

Let’s just keep the columns we’re interested in to make it more digestible.

We can merge all of the time series by time by using otp.merge function.

Parameter identify_input_ts here automatically adds SYMBOL_NAME and TICK_TYPE columns to the output, so each tick can be identified.

Generating ticks#

There are several ways to generate ticks without accessing the database. It’s very useful in case you want to check some algorithm fast or to create a test-case.

Classes otp.Tick and otp.Ticks can be used for this purpose.

otp.Tick can be used to generate a single tick for the whole time range:

data = otp.Tick(A=1)
data['B'] = 2
otp.run(data)
Time A B
0 2003-12-01 1 2

Or to generate ticks with some interval, for example every day:

data = otp.Tick(A=otp.math.rand(1, 100), bucket_interval=1, bucket_units='days')
otp.run(data, start=otp.dt(2022, 1, 1), end=otp.dt(2022, 1, 6))
Time A
0 2022-01-01 84
1 2022-01-02 92
2 2022-01-03 84
3 2022-01-04 11
4 2022-01-05 66

And otp.Ticks can be used to generate many ticks with different fixed values:

data = otp.Ticks({'A': list(range(5)), 'B': ['c', 'd', 'e', 'f', 'g']})
otp.run(data)
Time A B
0 2003-12-01 00:00:00.000 0 c
1 2003-12-01 00:00:00.001 1 d
2 2003-12-01 00:00:00.002 2 e
3 2003-12-01 00:00:00.003 3 f
4 2003-12-01 00:00:00.004 4 g

otp.Ticks can also be used to generate ticks from pandas.DataFrame:

import pandas as pd

df = pd.DataFrame({'Time': [pd.Timestamp(2022, 1, 1, 1, 1, 1), pd.Timestamp(2022, 1, 2, 2, 2, 2)], 'A': [1, 2]})
data = otp.Ticks(df)
otp.run(data, start=otp.dt(2022, 1, 1), end=otp.dt(2022, 1, 6))
Time A
0 2022-01-01 01:01:01 1
1 2022-01-02 02:02:02 2
