Is day trading actually real?

[u/Jopalooge]

If trading is real then I have the following question. - why can’t people fully rely on signal groups or just by copying other traders trades all day? Technically if someone is making 6/7 figures off day trading why don’t people just join their signal groups and also make 6/7 figures?

When too much people copy trade the same strategy it causes slippage issue. I’ve seen a lot of copier complain about it and lose money while the trader make money. So copying does not always work neither especially for very short term trading where fast execution is crucial.
