Day trading used to be the sole domain of the floor traders. They always have the advantage of bargains on commodities. They have the advantage of being able to judge the market breath, and thereby make the proper predictions with the correct price for a stock. However they don't get any commission or pay any commission.
The trend has changed and benefits brokers. They once paid a sizeable amount to day traders for brokerage or commission with systems, because they did not have market reports. This is not the age of trade done by papers only. Today's real trade is done by system. The trader decides whether to do short term trading or long term trading considering the market position and accessing the future market, because frequent changes in the market may put traders at risk of incurring embarrassing losses. Since there is a lot of media hype in the stock market and super volatile stock prices, -- caution and understanding are the name of the game.
Any one can, with minimal leverage, play to win without stock picking ability and without any money management. The future game really is not about the volatility of the prices but it has an extreme effect on the leverage.
Since the future is uncertain, day brokers are well managed with their teams and well equipped with the recent advancement of technology for conducting trading. The eagerness for money has become a mindset of peoples all over, no doubt for that the targeted future is to be achieved.
