How do i pick individual stocks to trade as a Technical Trader?

Use screener to filter. I use finviz.

This is such a difficult question to answer unless you share more about your method.

Are u a systematic or discretionary trader?

What methods do you use?
Trend following or swing trade?
Prefer range or trending market?

What medium do u use? Futures? Options? CFDs? Traditional buy/sell?

Scanners certainly help you to filter out things you are looking for but there are million different ways to trade and it’s difficult to give a structured reply on that
