There seems to be a gap (1 hour) in minute options data?

Alpaca Market Data

See this for example:

1 hour gap for this option:

Wed Oct 22 2025 16:31:00 GMT+0000

to

Wed Oct 22 2025 17:31:00 GMT+0000

I’m not sure if this is a usage problem on my end, or there simply just is a gap in the alpaca data? I checked the option in Thinkorswim, and there is no such gap. This gap should not be there.

In fact, for oct 22 2025, I think all the options have a gap around this time for 1-minute ohlcv bars.

@Mysterious_Shadow the missing bars you noted were the result of an outage by the Alpaca data provider. There is a bit more detail on the status page here.
