First question is what is intraday?

Intraday is the type of trading in which we have to buy and sell a share between 9:30 to 3:30 and we will get some discount on share price

What is long term?

It is a type of trading in share market there is no limit in buying or selling time

Which is best for me?

It depends on you and you work if you are a job person or busy person you should do long term and focus on your work

And if you do not have any job so you can earn regular income from intraday but its risky
