Hello, I need to know if data (for a given bond) provided by your API is reliable. Thanks

2/16/2026 14:00 IT537030= 1.99805
2/16/2026 15:00 IT537030= 1.92665

RIC: IT537030=

The data is about the yield

# Request BID / ASK yields

df_yield = ld.get_history(
universe=rics,
fields=["BID_YIELD", "ASK_YIELD"],
interval=INTERVAL,
start=START,
count=COUNT
)

INTERVAL = "hourly"
START = "2025-04-16"
COUNT = 10000

I did a few changes to the original dataframe

bid = df_yield.xs("BID_YIELD", axis=1, level=1)
ask = df_yield.xs("ASK_YIELD", axis=1, level=1)

df_mid = (bid + ask) / 2.0

to only have mids

df_mid = df_mid.between_time("07:00", "16:00")

so either the bid and/or the ask is wrong.

Thank you for reaching out to us.

Please clarify why the client asked if the data is reliable or wrong.

There is the MID_YLD_1 field for IT537030=.

INTERVAL = "hourly"
START = "2026-02-16"
COUNT = 10000
rics = "IT537030="

df_yield = ld.get_history(
    universe=rics,
    fields=["BID_YIELD", "ASK_YIELD","MID_YLD_1"],
    interval=INTERVAL,
    start=START,
    count=COUNT
    )

df_yield

The client can directly use the MID_YLD_1 field instead.
