I have placed some trades in IB as emergency measurement, but it is not frequent.I'm curious if anyone has placed trades, as I've wondered how I might track or price options. Since the SPX stops calculating at RTH closing time, I'm thinking that I'd use /ES as a proxy, while subtracting premium. I've gotten fills after the market closes on some Day orders with IBKR, but I'm not sure it that was driven by "clean up" trades from MM's balancing their books, or from price movement and pricing changes.
How about futures trading on ES after hours ? Is the liquidity good on large orders ?I have placed some trades in IB as emergency measurement, but it is not frequent.
For pricing options I think TOS reflects current prices, but not greeks.
For greeks you can look to TastyTrades - funny enough they show actually greeks (but not real SPX spot).
For spot estimation you can find an entry closest to 0.5 delta.
And with this neither TOS or TastyTrades allow after-hours SPX options trading.
