My thoughts.
Everyone is different, you might pick it up straight away, it might take years, who knows.
Every market works on Supply and Demand. Study
Wyckoff Stock Market Institute|Stock Market Technical Trading and
Jesse Livermore - Stock trading hero and womanizer
All markets are inherently designed to make you emotional, thus, you will make mistakes, if you submit to fear and greed subconsciously.
The only person you can trust is yourself.
Trade minimum position size, get the feel of winning and losing, demo won't give you this emotion.
In order to make millions, the formula is simple : Your win rate should be around 50%+ and your Risk/Reward should be about 10.
Keep your losers tiny (easy, but emotionally charged) and let your winners run (difficult and emotionally charged).
If you're wrong, you should know straight away and get out, before the market kicks you.
Never risk more than you can afford, or are comfortable to lose. (1%?)
If you make the commitment, make sure you give it a good go.
You've stepped into the hardest business on the planet (so they say) .......... but only if YOU believe it to be so!
All the best.
