you probly want to put in the hours to study the markets , learn the broker you are using, tools to use while you trade, read books about technical analysis and watch tims video lessons before doin any crazy trading. this is from my experience,i was trading without a clue, untrained eyes and mind in february and march. hadnt place a trade since cuz i was losing money taking dumb trades, so i studied many many hours since then and learned hell of alot, have yet to place another trade. but really

you will be glad you studied to make educated trades instead of shooting in the dark.
