Learn what happened yesterday from the Professional side

What you hear and read on the retail side of the market is totally different than what actually happened on the professional side. This is an important distinction to learn about because the professional side of the market is where 80% of all the market transactions each day, some 350 -400 billion dollars exchanging hands, occurs on the professional side of the market.
The professional side of the market is transacted on the Dark Pool ATS venues, there are 50 Alternative Trading Venues. There are only 13 public exchanges.
20% of all transactions are on the public exchanges and are retail investors, retail traders and small funds managers with less than 3.5 billion in assets.
The internal structure of the stock market is entirely different than retail traders believe.
It is far more complex and far larger. The speed of execution is on the millisecond which is 60,000 transactions per second. Retail trades on the 1 minute timeframe.
The Dow 30 started out the day with a huge Gap Up on HFT volume as the HFTs filled the queues of the market seconds before the market opened. This caused the gap up, NOT retail traders orders which were filled after the gap and run up. Try not to chase stocks or ETFs.
Then just before the Federal Reserve Bank Chairman Powell was going to speak, a surge of MEMEs groups, and Guru led retail groups rushed in and drove the value of the Dow and price of the DIA upward. With a mere 25 basis points retail groups, news, reporters, websites all reacted negatively as all were expecting a higher rate cut. The Sell Side Institutions, aka big banks, and professional traders already were filling the queues on the millisecond with SELL SHORT ORDERS pending a buy to cover WAY below their sell short order.
So the stocks of the Dow that had been speculated upward and the DIA suddenly collapsed as there were NO buyers and scant buy to covers. A VOID along with smaller funds VWAP orders drove Dow components down and DIA down. then the fundamentals of some Dow components were below the stock price. Dark Pools started buying these stocks at bargain prices as the fundamentals at this time were way above the price for those Dow stocks. The Buy Side made huge profits. The Sell Side made huge profits, the professionals made huge profits.
Most retail day traders and numerous smaller funds lost money.
