I wonder why anyone will waste , although It's definitely not for me?
Lets say you're watching 5 instruments, each at 20min, lets say you watch screens for 8 hours each day you get 5*3*8 = 130 pubs every day.
130 pubs, depending on how picky you're with your trades that can spawn any number of trades, for me it could be 5. Likely 1-2 trades largely if .
So much could go wrong whilst daytrading, you're under pressure to make quick decisions, you can overtrade, you'll get bored, mad in the markets, trying to earn money back into a rage, spiraling out of control and all the fantastic things that lots of people understand from daytrading.

Compare it to going through 130 tools after market close on daily bars. You buy 130 new pubs, less noise, you're more concentrated and aren't under time pressure to perform and make quick decisions.
Above all you do not have to wait for things to occur, if there is not a trade you can just move on to the next chart, maybe add a new trendline and move on.
This way of trading is really amazing for me I can not fathom why people would waste their time looking at intraday charts at all.

Could someone make the case for daytrading?
