Final answer:
The average spiking percentage in a gap up short without resistance depends on various factors and cannot be determined solely by the presence of a gap up. Resistance levels in the stock market are determined by other indicators or market conditions.
Step-by-step explanation:
The average spiking percentage for a gap up short without the existence of resistance in the stock market can vary depending on various factors.
A gap up refers to a scenario where the opening price of a stock is significantly higher than its previous day's closing price.
The spiking percentage signifies the magnitude of the price increase in relation to the opening price.
However, the existence or absence of resistance levels cannot be solely determined by the gap up short.
Resistance levels in stock trading are price levels where selling pressure outweighs buying pressure, causing the price to stall or reverse. So, whether or not there is resistance will depend on other technical indicators or the overall market conditions.
It is important to analyze the specific stock, its historical data, and the broader market trends to determine the average spiking percentage for a gap up short with or without resistance.
