You have too many posts at this forum that intraday trading is can not be successful and then too many posts about how "easy" intraday trading is.
Now you're on the "casino" theme.
What's going on with you ?
You're starting to look like when you lose money intraday trading...you attack it. Then when you making money intraday...you praise how easy it is.
Funny thing is while you're doing all of that contradiction...you also stated you're a profitable trader but not via intraday.
I'm starting to think the problem is
you...not the type of trading.
P.S. There are retail algorithm traders at this forum...some of them have stated they're successful. You should comb thru the algorithm threads at this forum to see whom they are. You may get more traction with your strange messages about
"no one can trade as HFT due to commissions" if you post that message at the below algorithm/automated thread.

There only needs to be just "one" so that "no one" becomes a false statement.
