A Gap Down is when a stock opens at a lower level than the previous day's low.
For example, if the previous day's high was 500, and the stock opened at 495, there would have been a 5 point gap down. This is considered a bearish signal.
This is also known as a Full Gap Down (as opposed to a Partial Gap Down which is when the stock just opens below the previous day's close).
Gaps are areas on a share price chart where the price of a stock moves sharply up or down, with little or no trading in between. Opening gaps can be caused by news releases (for example, if a company's earnings are much higher than expected) or events that happen while the market is closed, or technical factors (e.g. traders placing their orders, before the market opens).
