Cannot retrieve data

Hi Team,

Please can someone check the below and provide resolution.

Very good Denis – we’re definitely one step closer now. I’ve changed the password and…

import lseg.data as ld

APP_KEY = "ee1aca4f4d86445bb6d980c533b95686d86716b4"

RDP_LOGIN = "cip@vitol.com"

RDP_PASSWORD = "..."

session = ld.session.platform.Definition(

    app_key = APP_KEY,

    grant = ld.session.platform.GrantPassword(

        username = RDP_LOGIN,

        password = RDP_PASSWORD,

    ),

    signon_control=True,

).get_session()

session.open()

ld.open_session()

df = ld.get_history(

    universe="GOOG.O",

    fields=["BID", "ASK", "TR.Revenue"],

    interval="1Y",

    start="2015-01-01",

    end="2019-10-01",

)

I had to add signon_control=True as I was getting a Session quota error otherwise.

The session now has has an “opened” state and I see no errors anymore:

However, the data frame that ld.get_history returns is empty. I’ve taken the example snippet from pypi. I’m not sure which datasets I’m permissioned to query – perhaps there is something universal like FX that we could try to test?

Hi Cornelius,

Glad your session is now connected. Could you try EUR= or GBP= for FX. For Energy you can try the front month ice brent contract LCOc1. Let me know if you’re able to pull history.

Thanks,Denis

Hm, no luck unfortunately. This is what I’ve done:

df = ld.get_history(

    universe="EUR=",

    fields=["BID"],

    interval="1Y",

    start="2015-01-01",

    end="2019-10-01",

)

And the error message I receive back is

in get_history(universe, fields, interval, start, end, adjustments, count, parameters, header_type)

    210 if exceptions and all(exceptions):

    211     except_msg = "\n\n".join(exceptions)

--> 212     raise LDError(message=except_msg)

    214 if not any({adc_data, hp_data, cust_inst_data}):

    215     return DataFrame()

LDError: No data to return, please check errors: ERROR: No successful response.

Its better to get the client to directly interact with us on these forums.

The code snippet above is correct and should provide a valid dataframe with results. Please ask the client to enable debugging for LD Library as described in this example.

{
    "logs": {
        "level": "debug",
        "transports": {
            "console": {
                "enabled": false
            },
            "file": {
                "enabled": false,
                "name": "lseg-data-lib.log"
            }
        }
    },…

The only change I did to the original code is to set the opened session as the default for the library:

…
	signon_control=True,
).get_session()

session.open()
ld.session.set_default(session)

df = ld.get_history(…
