2015 I ended up double up on a biotech, 2k to 4k in just a few months. That was pure luck, but here is my chart for 2016... YTD.
I say most is just finding good uptrending stocks that are under valued. And another good chunk of it was good swing trades for biotechs, and oil type companies.
Most trades this were with SUNE, CHK, AVXL, AMAT, and FOLD
My personal view on day trading.
STRESSFULL AS HELL!
My first few days last year made me have a few strokes i swear....
My 2nd trade ever ended up turning red within 2secs of buying. Then it dropped to -100 on the day. The next day was down over 1000. About a 50% loss...
Price ended up recovering and i made a bit, but looking back i should have actually sold.
If you are actually "day trading" and never holding over night you must be VERY VERY strict on your stop losses, and take a % loss and just walk away. Have a good risk/reward plan and stick to it. If you think "oh it will go back up" you end up holding the shares for weeks on and end and you are losing lost opportunity with other trades.
And remember, day trading is a skill, something you learn.
It isn't like what is talked about on this site. You do not just go out and BUY a stock then sell it once it turns green.
Trading with TA or the books are two big ways to trade. And both take a long time to learn. If you don't, you truely just are gambling....
If you do want to try it. Try it with paper money, and BE HONEST. Like be super honest with yourself when you do your trades. And do it for MONTHS and MONTHS, until you can ALWAYS end your months in the green.
