Trend day up, trend day down. I enjoy them all the same. True enough ... there was a thread elsewhere today with an article link that discussed this very thing. Here is the thread: https://www.elitetrader.com/et/threads/the-stock-market-works-by-day-but-it-loves-the-night.329764/ And here is the article: https://www.nytimes.com/2018/02/02/your-money/stock-market-after-hours-trading.html
Notice how days before and after the gaps had jumps from close to open but no gap is shown. Gaps come from un-printed territory, not from the jump between open and close. If they did, gaps would be commonplace----and they just aren't
The island like swing low left behind suggests it will be filled - does price hit 2800 first or is tomorrow a trend down day to close..? ...another unfilled gap to 2641..
