I'll have to go back and check what the date was but i think it was in the last 2 weeks. I just opened up the 1min chart and started scrolling backwards on tradingview.Strange ...
Why are you shy to disclose the date?
Those would be hardcore scalpers.Day traders love such massive movement.
If its good data then i imagine it is someone trying to buy too many contracts at once so they blow through the order book which must be a bit thin.the spike could be bad/garbage data,
or it could be good data (price really went up and down rapidly).
