Spike in historical data for TSLA (pre market)

[sobakasu]

I have noticed a strange bar in historical market data for TSLA.
this comes from the /v2/stocks/bars historical bars endpoint.

The rogue bar is the 1 minute candle on 4th March 8am (New York).
I don’t see this blip in trading view. What could be the cause of the difference?

I’ve noticed some 8 am spiking bars, for example on RXT 10/21/25. My GUESS is this is a dark pool order reporting time. I’m tempted to exclude 8am bars from my technical analysis. If anybody has additional information, this would be very helpful.
