Combination of strategy is required

My strategy changes in every few days. But generally i follow below strategies to decide on buy or sell:
1. Technical chart: You may get an idea on when to buy or sell based on technical chart which i believee works positive for me 60-70% of the time.
2. Research: This is most important factor for deciding on stock and may help you to decide long/short term decision on the stock.
3. Fundamental: Related to previous point. But if the stock is good fundamentals you can decide to add at each dip.
4. Any news and its impact: This is very important and generally drives the prices. Based on the news - positive or negative and its impact - short or long term, we can decide. poistive news can be new contract, good dividend announcement etc.Negatove news can be losing some contract or fallings sells number etc
5. Market Sentiments: stock prices generally fluctuates based on the sentiments. So, if you have done your research you can easily decide if its right time to buy/sell.
6. Your goal: As i mentioned earlier, your goal is important. If you know your risk apetite, you can set upper and lower limit for the price fluctuation and decide to add/sell. Say, m happy with 10% profit, i will try the book the profit fully or partially at each 10% milestone. we may set some threshold for loss as well say 5% based on the risk apetite and sell if the threshold is reached. The goal can be changed based on points above.
