Keep and ensure, your trading setups are so simple..
You should have skill to identify the direction in the running market.... with simple logics...
Don't focus do many things.......like...open interest / Call put ratio / volume / Fii - Dii and bla....bla..... nothing works out, if there is no setup....
Interpretation of levels are more important...... if you do so, rest all will fall in line with the setup....
How to do it --->> spend time and learn..... minimum 10 years is required to reach that level...or you should have a experienced mentor to guide to you or transfer his experienced knowledge to you.
Identifying setup is a easy job.... if you have skill....or else.... please quit trading....and do something else....
Cheers....
