Conspiracy or stupidity – you choose. The fact remains that no one who wants as good a price as possible dums 7728 contracts in a minute. That just DOESN’T happen. Sure, it can be a bot gone hay-wire. Or a fat finger. Or someone really, really stupid. I’ll agree to any of those. Or it can be someone who has figured out a way of earning money on rapid swings in the gold price.
All I know is, trading such markets is pure insanity. Investing, sure, but not trading.
