There are so many intraday trading strategies based on the technical analysis. One simple strategy, which is extremely simple and useful for a beginner is RSI strategy. RSI is relative strength index, which gives information about whether the stock is overbought or oversold. Based on the RSI value it is possible to make some profitable trades.
This video shows how I used RSI value for making a profit of 8000 rupees in less than 22 minutes.
But one should be careful (i.e., particularly beginners) while using RSI for day trading, because the stock can remain in overbought or oversold condition for a longer time frame which may cause losses to your trade.
For more information on RSI, please comment your queries, as I will try to prepare a video about RSI strategy in detail.
