TD Ameritrade API Options Chains Getting wrong values for Greeks (Delta,Vega....) -999

Question

Calling the TD Ameritrade API for Get Options Chains at https://developer.tdameritrade.com/option-chains/apis/get/marketdata/chains#, I keep getting strange -999 values for the greeks here is a snippet. I have tried both ANALYTICAL and SINGLE for strategy. This is what I get back, any ideas what I am doing wrong ? :

• "volatility": -999,
• "delta": -999,
• "gamma": -999,
• "theta": -999,
• "vega": -999,
• "rho": -999,

TDAmeritrade Answer- "If you are referring to the Greeks, this is something that we will look to correct after integration with Charles Schwab which we estimate will take 30-36 months. For your other email around alerts, we do not have an alerts endpoint."
