Have you guys noticed that every day around 5:00 pm EST that the market dumps, it has to be Wall Street taking daily profits before they go home for the night. Its only on weekdays and has happened the last 3-4 weekdays in a row and on Fridays its s bigger dump before they go home for the weekend.
I didn't noticed this but if you do, you can take this as your strategy and do some experiment while executing this discovery you made.
