Error message
Error: Not enough information to complete the operation. Likely due to zero values in the IV field.
What it means
Raised by OptionsChainsData.skew() in the by-strike mode (moneyness=None): after iterating expirations and appending per-expiration call and put frames with 'ATM IV' and 'Skew' columns, either call_skew or put_skew is empty. Unlike the date mode, this branch computes skew across strikes for each expiration and needs both sides populated.

Solutions
- Check per-side IV coverage: df.groupby('option_type').implied_volatility.apply(lambda s: (s > 0).sum()).
- Switch to a provider/date with two-sided IV surfaces.
- Populate or repair zero IVs before calling (e.g. recompute from option prices) if you own the data pipeline.
- As a diagnostic, run skew(moneyness=..., date=...) mode which surfaces which side is missing via the sibling error.
Example fix
# before
skew_df = chains.skew() # all put IV zero -> put_skew empty
# after
data = obb.derivatives.options.chains('SPY', provider='cboe')
skew_df = data.to_chains().skew() Defensive patterns
Strategy: validation
Validate before calling
df = chains.dataframe pos_iv = df[df.implied_volatility > 0] assert (pos_iv.option_type == 'call').any(), 'no call IV' assert (pos_iv.option_type == 'put').any(), 'no put IV'
Type guard
def two_sided_iv(df) -> bool:
pos = df[df.implied_volatility > 0]
return set(pos.option_type) >= {'call', 'put'} Try / catch
try:
chains.skew()
except OpenBBError as e:
if 'Not enough information' in str(e):
chains.skew(moneyness=95, date=30) # fall back to moneyness-date mode for diagnosis Prevention
- Verify both sides carry positive IV before strike-mode skew.
- Repair or drop zero-IV rows upstream instead of relying on the library to fail.
When it happens
Trigger: Calling chains.skew() (default strike-mode) where no expiration produced both a call frame and put frame with valid IV - e.g. all put IVs are zero so put_skew never gets appended (the append only happens when len(put_atm_iv) > 0).
Common situations: Providers with one-sided IV coverage (puts quoted, calls IV=0, or vice versa); symbols with very few listed expirations where the single expiration lacks ATM IV; IV columns containing NaN cast to 0 upstream.
