Explain gaps in stock charts. What happens with open limit orders from the day before, when a gap occurs?
When there is a price gap on a stock chart, it means that there was a difference between the current price and the previous closing price. This can happen for several reasons, such as a company experiencing financial difficulties or a new product launch.

Open limit orders are placed below the market price of a security and will be filled at that price if it becomes available. If there is a price gap on the day before an order is placed, the order may not fill immediately because the seller does not have enough shares to sell at the higher price. In this case, the order remains open until the next trading day, when the seller might decide to sell the shares at the higher price or cancel the order entirely.

It's important to note that price gaps do not always mean that a stock is about to fall in value. They should be considered along with other factors, such as news headlines, technical analysis, and investor sentiment, to make informed decisions about investing in stocks.
