Hi all,
I have some years of experience in investing in stocks; a couple of years ago I started to explore the more speculative swing and daytrade.
Quite recently the tech support of 2 of my charts providers and brokers started to explain me to stay away from short timeframes 1/5 minutes and focus on moderately longer charts, in particular the 12h.
( Of course I’m aware about the dangers of daytrades, common sense wise 
)
