useRTH=False doesn't show post-market trades

[NumberChiffre]

Hey guys,

I'm trying to grab data outside of RTH for SPY, so I'd expect pre-market and post-market data, but I can only see pre-market data. Is there a way to include post-market data which should go from 4-8PM EST?

If there's a forum that lets people post questions like these, please share it here and I'll follow up there!

symbol = "SPY"
contract = Stock(symbol, "SMART", "USD")
bars = ib.reqHistoricalData(
    contract,
    endDateTime='',
    durationStr="1 D",
    barSizeSetting="1 min",
    whatToShow="TRADES",
    useRTH=False,
    formatDate=1,
)

                             open    high     low   close   volume  average  \
date
