it is true: the brokers and exchange are the consistent winners.
and the game is not zero sum.
when two parcipants put into $100 in a trade ( a buyer and a seller), the loser lose his commisin and fees, plus his $100 worth trade, also the winner lose commission and fees, he/she does not win $100, he/she needs pay to collect his rewards. so we have two losers if you stand in the view of brokers and exchange.
only if we go curb trading.
day trading is hard. sure it is. even looks every day is the same kind of up/down. but from mathematical point of view, the combinations of up/downs is unlimited. the kind of up/downs you bet is just a small set of them, so the odd is very low, just like picking a needle in a sea. the more you zoom in (the magnitude of up/down) or the smaller the timeframe, the more combinations (tick to tick, quote to quote, one1minute to 1minute bar) you get, so the less chance the expected up/down event will occur.
but if you zoom out a little bit, less combinations are there. for example, 100points move in NQ in a day session is very rare, in other words you have slim chance to get 100point move either against you or in your favor. 3points move is just one 1' bar, in a day there (9:30 to 4:00), there are 6.5*60 bars=390. you will see 390bars, your odd to win your 3point move is slim since there are too many 3points there, the particluar one you expect is just one of them, if you think each 3point move as an indepent event, the chance to win your 3point move is 1/390. of course it is not that kind of low, but that tells you: you should bet on high probaility event, while not low odd event.
most people have an illusion about high probability and low probability. they may think 3point move is a high probability event, but the probability of to win a paticular 3point move which you expect is very low. I can almost 100% be sure next monday NQ will not have 100 point either up/down, that is the high odd of betting, even though it is a low low probability event. or I even further claim none of those five days will have 100points move (tuesday AAPL earning may cause such exception).
day trading is just this illusion. I once see one tutorial to cateer day trading use a gap down example, a stock trends very well up, around $80, then something like peer compettitor or financial maniuptaltion news release overnight, the stock gap downed to $10, lost almost 90% of its value, so the daytradeing tutorial claims you should do day trading otherwise you see you lose so much.
actually it is misleading, if you short it before the news release or you buy put options, hold overnight, man, one deal you are in the rich people 10% club.
day trading is just one way to make money. but the requirements to day trade successfully is higher than any other ways: such as option trading betting on scheduled event, stock swing/investment. you must be able to reponse to the market on the fly. if you do others, you have plnty of time to plan your trade, so the trade quility is high. for example, option earning play (you know the date, market expectation etc. beforehand ), or trend following in a trending market (you can easily see the trend whether using EMA or trendline methods, what event such as FDA drug approval agenda etc./earning)
day trading really is not for everyone.
