Technical Analysis is based on the "sentiments and insights" of traders. and even known as behavioral finance. It is particularly study of charts and the their price and volume to judge the trend. In this analysis we can also follow Indicators but we only need to master one particular indicator for buy/sell strategy. It is more accurate and precise then fundamental analysis.
Trader must follow below strategies for their buy/sell decisions:
1. Buy at Support
2. Sell at resistance.
3. Buy when any positive news comes into the market.
e.g. Reliance Jio news leads to increase in stock price
e.g. When company announces their profits
4. Use appropriate indicator for buy/sell decision
5. Go for Exponential Moving Average rather than Simple Moving Average.
6. Judge logically and critically Price and Volume and their volatality.
