Technical indicators are algorithms represent the price and volume. It is not a direct reflection of the price actions as compared to technical analysis. It is the simple average of the Closing prices – Daily – over a period of time Eg: 14 days, 30 days, 1 year, etc. and divides the closing prices by the no of days. RSI is Relative Strength Index. It is very useful in the non trending zone. When the index crosses 30 and moves above 30, it is a signal for bullish trend. That time BUY order can be initiated.
