I lost 50K in Union Bank's F&O in a single day when PNB posted result on 7 August.. Should i continue to trade or take break

F&O

Then 1 min is not your TF.
Selecting and finalizing a trading strategy is more complex than shopping with better half.
You need to custom match everything unless it fits . TF, strategy, entry, exits all need to be tested and custom fitted.
Continue trial and error - until you get it.
