I know this may sound dumb but since I am a beginner I think it’s important for me to ask. So my question is how do I get intraday charts for technical analysis? Suppose: I want to track minute-by-minute price tracking of Wednesday trading hour. I looked at nepsealpha but they could provide me data only up to the last day(Tuesday). Do I need to pay subscription if there is any or can I have it for free?
