Which is the best time frame used by Intraday traders?

Intraday TF is depend on your analysis. For best results use 5min TF for execution or you can use 3min also. And for analysis you can go with 15min and 1HR TF... Index and stocks both can be traded on this with MTF analysis.

Happy Investing

I usually use 15 mins time frame for intraday. However, it depends on the market.

Usually 15min is the best TF to used in intraday

It completely depends on weather you are Buying or selling the Scrip/Strikes. And the type of trader you are.

One-minute time frame is the best for intraday trades, but you must master the technicals by heart.

Market open hone pr 1 hour 5 mint and uske bad 15 mint.

It Depends on  index or stock . 15 max  3 min
