Here is a nice synopsis of the various 'legal' and not so legal but overlooked-by-the-snoozing-regulators ways in which the financial trading desks and hedge funds manipulate markets intraday.
In some ways this is from the dark ages, because HFT algos can do the job so much better.
But all the basic principles remain the same, including manipulating the financial news and painting pictures with key markets, like the SP 500 futures for example.
And it is always a plus if your rigging of the market is along the directions favored by the big Wall Street Banks and their Federal Reserve System.
As a reminder, the UK is expected to 'trigger' Article 50 (Brexit) tomorrow. Brexit is not a one off event, but will involve a negotiation process that will probably drag out over a couple of years. Still, it is a sign of the times.
The Historic Moment Draws Near for Brexit
As always, non-professionals should never try to trade short term in these markets. They are far too bent in the favor of insiders and pros. I doubt that it could be more obvious anymore after the revelations of the last seventeen years or so. I don't know if it is the worst in the post WW II era, but it pretty much seems to be right up there with the 1920s.
Get right and sit tight.
This has been a public service announcement. lol
