Its pure Elliot Wave theory. Look closely, there are trendline, Retracment line, wave line matches the same line in 37500.
So it will upto 37500 then it will fall upto 36500 within a week.
After that it will go for very long upside upto 37800.
For Monday go for long after 37300 to 37500. Sell for short after 37500 to 37300.
Education purpose only. Thank you.
