Does anyone know if the options chains are from 1 or from more than 1 exchange?
I've tried to iterate through an OptionChains IEnumerable variable, and I cannot tell if there's more than one contract at every right/strike/expiry point.

Our options data is the entire OPRA tick feed condensed into Minute bars. This covers all the exchanges.
We have a Buy and Hold Options Boot Camp lesson coming up soon. Hopefully, we'll get it published later this week. If you complete the rest of the Boot Camps options will become easier.

Thank you Jared. I did complete 3 more Boot Camps this morning.
I look forward to the Buy and Hold Options Boot Camp. I'll keep an eye out.
I am building a collared strategy using dividend stocks. Eventually, I want to evaluate various put/call pairs at expirations that correlate to 2, 3, & 4 future dividends and strikes that are -3, -2, -1, 0, & +1 to the current underlying price. From all that I have read thus far, it is not a) apparent that an OptionsChain has only 1 memeber at a given <Right, Expriration, Strike> combination nor b) how to iterate through OptionsChains members to select a chain.
Can you tell me how many chains correspond to any given <Right, Expiration, Strike> combination?
Can you tell me how select unique combinations please?

Hi Craig,
It is correct that each OptionChain only has 1 member at a given <Right, Expiration, Strike> combination. See the attached backtest's log for reference.
To iterate through the OptionChains, we can write
for symbol, chain in slice.OptionChains.items(): chain # OptionChainTo determine how many chains correspond to a given Right, Expiration, Strike> combination, we can use the following snippet inside OnData:
self.combinations = pd.DataFrame() for symbol, chain in slice.OptionChains.items(): for contract in chain: row = pd.DataFrame({'symbol': [contract.Symbol], 'right': [contract.Right], 'expiry': [contract.Expiry], 'strike': [contract.Strike]}) self.combinations = self.combinations.append(row) # Calculate number of chains per combination chains_per_combo = pd.DataFrame() df = self.combinations for i, row in df.iterrows(): num_chains = df[(df.right == row.right) & (df.expiry == row.expiry) & (df.strike == row.strike)].shape[0] if chains_per_combo.shape[0] == 0 or \ chains_per_combo[(chains_per_combo.right == row.right) & (chains_per_combo.expiry == row.expiry) & (chains_per_combo.strike == row.strike)].shape[0] == 0: sub_row = pd.DataFrame({'chains':[num_chains], 'right': [row.right], 'expiry': [row.expiry], 'strike': [row.strike]}) chains_per_combo = chains_per_combo.append(sub_row)To select a unique combination for a single symbol, just select a contract while looping through the chain as each symbol has unique <Right, Expiration, Strike> combinations.
for symbol, chain in slice.OptionChains.items(): for contract in chain: contractSee the attached backtest for a full example.
Best,
