# otp.oqd.OHLCV

### *class* OHLCV(exch='all', start=utils.adaptive, end=utils.adaptive, symbol=utils.adaptive)

Bases: [`Source`](../source/root.md#onetick.py.Source)

OneQuantData™ source to retrieve a time series of unadjusted
prices for a symbol for one particular pricing exchange of daily OHLCV data.
Output ticks have fields: OPEN, HIGH, LOW, CLOSE, VOLUME, CURRENCY, EXCH.

* **Parameters:**
  * **exch** ([*str*](https://docs.python.org/3/library/stdtypes.html#str) *,*  *'all'* *,*  *'main'* *,* *default=all*) -- 

    The OneQuantData exchange code for the desired price series. Possible values:
    - 'all'
      : return data for all exchanges;
    - 'main'
      : return data main pricing exchange;
    - any other string value will treated as exchange name to filter data.

    Default: 'all'.
  * **start** ([`datetime.datetime`](https://docs.python.org/3/library/datetime.html#datetime.datetime), [`otp.datetime`](../datetime/dt.md#onetick.py.datetime), [`onetick.py.adaptive`](../misc/adaptive.md#onetick.py.adaptive), default= [`onetick.py.adaptive`](../misc/adaptive.md#onetick.py.adaptive)) -- Start of the interval from which the data should be taken.
    Default is [`onetick.py.adaptive`](../misc/adaptive.md#onetick.py.adaptive), making the final query deduce the time
    limits from the rest of the graph.
  * **end** ([`datetime.datetime`](https://docs.python.org/3/library/datetime.html#datetime.datetime), [`otp.datetime`](../datetime/dt.md#onetick.py.datetime), [`onetick.py.adaptive`](../misc/adaptive.md#onetick.py.adaptive), default= [`onetick.py.adaptive`](../misc/adaptive.md#onetick.py.adaptive)) -- End of the interval from which the data should be taken.
    Default is [`onetick.py.adaptive`](../misc/adaptive.md#onetick.py.adaptive), making the final query deduce the time
    limits from the rest of the graph.
  * **symbol** (str, list of str, `Source`, `query`, [`eval query`](../misc/eval.md#onetick.py.eval), default= [`onetick.py.adaptive`](../misc/adaptive.md#onetick.py.adaptive)) -- Symbol(s) from which data should be taken.
