Low Risk - High Reward trades (like, a few ticks of stoploss, and a hundred pips of profit target), and a lot of winning trades!
Plus leverage of course
That made me laughThat's what billionaires do pre-market. You should see what they do in the real markets! Insane negative tick stop-losses, multiple trades in alternate universes and leveraging their in-laws for a double-plus good whammy in the morning. And we haven't touched base on breakfast yet!
Let me offer you a look from a different angle:If you are day trader you can make decent income, you can actually earn quite a lot but the fact is there is practically 0% chance that you will end up in top 100 forbes list if you are just doing day trading
What kind of investing/trading do you have to do to become SUPER rich, like earn BILLIONS$? What should be your approach in theory?
Let me offer you a look from a different angle:
If you day trade for a living you are unable to take advantage of the magic of compounding and will likely not be very rich in the long run.
Compounding is what can make you very rich if you are able to generate yearly gain of 20%-25% which most day traders on ET claimed were easily obtainable.

Tell me: how long do you have to compound your $5,000 "in the long run" to achieve this? You can make an estimation in years (months and day are not relevant). If you use your "in the long run" strategy and make 100% net return a year (which is not realistic at all), you will need 10 years to get to the $5,100,895. But in the meantime the daytrader will have reached 10 times more as he generates each year $5,000,000.

FACT is that the majority of all people are even not able to be profitable in LT trading. But that does not change the FACT that you can make good money in the hypothetical example I gave. And beat LT traders. I also believe more than 0.01% are consistent winners, this 99.9% is a myth that goes around but nobody ever proved it.
