Final answer:
To short a stuffed candle during a gap up at the market opening, you would need to determine the minimum volume requirement. However, the question does not provide enough information to determine the specific requirement. It is important to consult with your broker or financial advisor for the specific requirements.
Step-by-step explanation:
In the stock market, a gap up occurs when a stock's opening price is higher than the previous day's closing price. Short selling refers to selling borrowed securities in the hopes of buying them back at a lower price to profit from the price decrease. To short a stuffed candle at the market opening with a gap up, you would need to determine the minimum volume requirement.
Unfortunately, the question does not provide enough information to determine the specific minimum volume requirement for short selling a stuffed candle during a gap up at the market opening. The minimum volume requirement can vary depending on factors such as the stock's price, liquidity, and your broker's requirements.
It is important to consult with your broker or financial advisor to understand the specific requirements for short selling and determine the minimum volume needed to execute a gap up short at the market opening.
