What is the best intraday trading strategy for large cap stocks?

I want to know about the intraday trading strategy for large cap stocks. I am new to intraday trading. So, please help me.

If new to intraday, I suggest to first read and identify a strategy that suits you. Then paper trade that strategy for a while. Fine tune your strategy on what you learnt from paper trading. Once you are comfortable, then start with real money. Unless we use real money, learning will be less, but still paper trading for a while helps. Start with small amount and then increase the capital if you are profitable consistently.

Look for Nifty 50 stocks top 10 gainers and losers. Wait for 15 or 30 minutes. then take trade if the break out happens on either side of high/low made in first 15/30 minutes. You can search online for ORB (Opening Range Break out) strategies to learn more.
