Well there are some folks here who obviously know what they are talking about, but those who claim they have a 95% success rate are flat out liars...
Been trading stocks for over 5 years, now more actively involved in futures trading (mainly S&P, gold, crude oil and nat gas), and some forex. Many people prefer to trade forex futures rather than the forex spot. Its a very liquid market (depending on time of day), better executions, greater transparency, and your broker isnt trading against you.
All markets are manipulated to some degree, particularly in the forex/futures market. If you know what to look for, you can often take advantage of this. Also, we as small individual traders can stay nimble and get in/out of a position easily.
Trading can be a very stressful, mentally challenging occupation. At the end of the day, it doesn't matter what you trade, it is imperative you adhere to commonly cited trading rules, for example, using manageable position sizes, always having an exit plan for both winning and losing trades, using mental or hard stop losses etc.
One rule to pay attention to is risk/reward. I only enter trades with a minimum risk/reward profile of 3:1. For example, I risk $100 to make a min $300... I am a profitable trader with a winning trade percentage of around 55-60%. Some traders I know have even less winning trades, but when the win they win big, and keep their losses small. If I make 9 trades in a day, with a 3:1 risk/reward profile, and only win on 4 of them, I can still be highly profitable... Winning trades (4 x 300 = 1,200) less losing trades (5 x 100 = 500) = 700 net profit.
That is a simplistic analysis, but I just use it to show the importance of using solid trading rules, and only entering good risk/reward trading set ups.
Its important to remember, your opinions on what a trade "should" do is irrelevant... The market is always right, rarely rational, and it screws the most people most of the time.
My advice, definitely learn the basics of technical analysis which apply to almost all markets from stocks to commodities, futures, forex etc. Practice with demo accounts (I know, it seems boring but will definitely save you $$$ in the long run).
Follow some reputable traders on Twitter... Yes, there are some fantastic TRANSPARENT follows on Twitter with a lot of knowledge and experience.
If you are into forex for example, follow some of the folk at dailyfx.com... They aren't always right, but nobody is. But they provide some great insight, and actionable trading ideas. There are Twitter users for all markets - just have to find them. I have a great stream of follows for stocks and futures trading, if you want you can hit me up.
And stay away from paid newsletters that promise you unrealistic looking returns.
