What are the sources uses by traders to pick the stocks to day trade

What are the sources uses by traders to pick the stocks to day trade apart from news. Since there are thousands of high volume stocks on day basis.

Moneycontrol - Top gainers, Top losers

Could you please tell that what time I should check top gainers and losers

Around 10-10:30 would be fine

Full day, more important is Hourly gainers, hourly losers

You can filter them for Nifty 50 stocks or Nifty 100 stocks

I keep two tabs open - One is Nifty 100 stocks hourly gainers/losers, second is All stocks Hourly gainers/losers

But be careful while chasing momentum like this, the gainers or losers list will choose or narrow down stocks for you, but which one you choose and at what price you choose is more important

Sorry i mentioned Moneycontrol website, actually correct website is Economic times which shows Top gainers/losers very well
