you can do it with algorithm and automate trading logic through a combination of software and supported brokers.
The traders at big banks do this all the time, they make hundred or thousand of trades automated with little intervention, pocketing $50, $100, $1000 a tick.
Small amount but multiple by 1000s it becomes a very large number.
If you know a certain business or stock well you can do this and make reasonable income stream fairly easily but you got to know your stuff or
you get eaten and lose your capital.
There are people they make their living by just trading Microsoft stock all their life, yup one stock Microsoft.
this is the sort of stuff no one teach you, once you acquire enough knowledge and experience you know what to do and just quietly rake in the cash with little stress...
with stock market if someone got something that rake in the cash, they never tell you..the one that sell course and seminars are just that selling course and seminar they don't know how to rake in the cash.
I sort of do this and I just pocket $1000 here $2000 there $500 over there
through out the year..some weeks I pocket $2000, other week $500..this is just trading activities within a certain business I know very well, then you get the dividend stream on top and capital gain for longer term holding etc...
