Market recent trends still follow a bit of a pattern.

Every afternoon shorting, then from the opening of the US stock market until early morning, go long, then around noon to afternoon continue shorting. But the specific timing points cannot be precisely mapped, only to follow this pattern and slowly explore.
Then suddenly one day, a rapid decline occurs, of course, it could also be an increase but the probability of a decline is higher.
This segment of the market should still be quite easy to pick up some living expenses, can stop loss lightly and play slowly, but profits earned from this pattern are easily wiped out by sudden large fluctuations later.
