As an AI language model, I can provide you with some general guidelines for buying or selling stocks based on real-world stock market indicators. However, please note that investing in the stock market involves risks, and it is always recommended to consult with a financial advisor or do thorough research before making any investment decisions. Here are some indicators to consider:

1. Fundamental Analysis: This involves analyzing a company’s financial health, including its revenue, earnings, debt, and market position. If a company has strong fundamentals, it may be a good buy. Conversely, if the fundamentals are weak, it may be a sell signal.

2. Technical Analysis: This approach involves studying stock price patterns, trends, and trading volumes. Technical indicators like moving averages, relative strength index (RSI), and MACD can help identify potential buy or sell signals.

3. Market Sentiment: Monitoring market sentiment can provide insights into investor behavior. Positive sentiment, such as optimism about economic growth or a company’s prospects, may indicate a buy signal. Negative sentiment, such as concerns about economic downturns or company-specific issues, may suggest a sell signal.

4. Valuation Metrics: Evaluating a stock’s valuation relative to its peers or historical averages can help determine if it is overvalued or undervalued. Common valuation metrics include price-to-earnings ratio (P/E), price-to-sales ratio (P/S), and price-to-book ratio (P/B).

5. Economic Indicators: Keeping an eye on macroeconomic indicators like GDP growth, inflation rates, interest rates, and unemployment can provide insights into the overall health of the economy. Positive economic indicators may support a buy decision, while negative indicators may suggest a sell signal.

Remember, these indicators are just tools to assist in decision-making. It’s important to conduct thorough research, diversify your portfolio, and consider your risk tolerance and investment goals before buying or selling any stocks.
