TLDR: Research, do some simulated trades on investopedia.com to get the jitters out, profit. Buy low, sell high, and trade with the trends. Listen to other traders with a grain of salt, and if you can't hang hire a pro.
I am mixed on some of the opinions being thrown out, so I'll offer my own experience.
I jumped into day trading after playing world of warcraft extensively (I know, I'm ashamed) and playing the game auction house. The rules of the auction house are exactly the same as the market though: buy below the market price, and sell above the market price. In the game world, it is not possible to know market price without "addons" to the game to track this data. The same is true of day trading.
You COULD just go strictly off price, buy low sell high, but how do you know if you're trading above market? How can you best estimate if the market will go up or down from the price you're buying? Are you buying at a premium or a discount?
You HAVE to use indicators, but keep in mind indicators aren't limited to the stuff you throw onto a chart. Reading balance sheets, understanding fundamentals, keeping up to date on market news....these are all tools in your toolbox in addition to things like schochastics, bollinger bands, moving averages, etc...You need to find out how YOU want to trade, and then find out what tools best serve YOUR trading style. Someone earlier said "the market is random." This is bullshit. Prices move for a reason, and "random" price movements can typically be attributed to human emotions. If you're going to be successful in any kind of trade you must understand the market, possess the ability to analyze it, and anticipate price movements.
So, how do you do that? Research. Youtube, investopedia.com, google, ET, the internet period. If you think day trading is free money, you need a reality check; the amount of research and observation a day trader performs basically equates to a full time job. A typical active trader watches the market from open to close, and then performs additional research after the market closes. If you're trying to ask how to day trade without putting in your own research, you're better off hiring a professional to manage your trades.
That being said, here's the best advice I can give you:
1) Research. You have to develop your own trading style. Are you trading stocks, ETFs, MFs, options, forex..? Are you doing multiple trades per day or buying a few a week for short-term holds? Are you going to short sell? Do you know what limit, stop, and trailing stop orders are? Stocks will probably be the easiest entry for a beginner, but you still need indicators. Learn how to read a chart, and I would recommend looking up the following terms as a MINIMUM for charts: Moving Averages, Bollinger Bands, Momentum, Schocastics, Pivot Points, Resistance/Support Lines, Volume, Candlestick patterns....the list truly is endless, and these are only very basic indicators. If you need charts for free try

2) Practice. Investopedia.com has a great simulation with 20 min delayed stock quotes. You can join one of the mainstream games, or create your own game that matches your own trading parameters like starting capital. This allows you to trade/test strategies risk free, and can acclimate you to the process of buying and selling before actually putting money on the line.
3) More research. Now that you know how to "play the game," you've gotta find what you're going to buy. Charts can tell you a great deal, but don't forget about the other resources out there. You can find analyst opinions, fundamentals, technical analysis, balance sheets, etc. on everything you want to buy. Which strategy you employ will dictate which tools you want to use/exclude.
4) DO IT. Open an account with a broker and start making that money. The market isn't so much 'random' as it is 'uncertain.' The better you are at predicting entry and exit points the more successful you will be.
5) MORE RESEARCH. There are people (including some on this website) who have decades of trading experience, and you should use that to your advantage. The market can be a gritty place; listening to the veterans while evolving your own trading strategy is key. A day doesn't go by I don't learn another tool or tip.
To put this rant at an end...you've got to do your own homework and weed out the good and bad, and if you aren't willing to put the effort or don't have the skills you really should hire a broker to manage your trades for you. BUT, if you're willing to learn and have the aptitude, you too can join the ranks of the many caffeine-addled, sleep deprived, stressed-beyond-belief day traders who enjoy the freedoms and lifestyle of making money off of capital.
Buy low, sell high, and happy trading my friend I wish you the best and good luck!
