Hello all, FYI to all that would potentially pull SPY options through the market/options/search endpoint.

One of the exchanges introduced "Jumbo" options on the SPY last week.  This new option contract has a contract size of 1000 vs. the normal 100.  TradeKing will not support trading on these at this time.  We might reconsider if the volume and liquidity of these contracts improves.

Our market data provider will still send these options through the option search endpoint, causing duplicate strikes for your response. When using this endpoint on SPY options, you may need to programically filter these options.  You can key off the root symbol field for "SPYJ" or you can leverage the contract size field that shows "1000"

Please let me know if you have any questions.

Thanks,
Mark S.
