I would like to work Wall Street, buy and sell stocks. Is the title of this job "investor", "investment banker", or something else? I have no clue what it is called to sell and trade stocks like in the movie Wall Street: Money Never Sleeps (Michael Douglas & Shia Labeouf).

Thanks in advance!

Answer
The job title is a Trader.

Trading involve... well trading stocks on the market.
There are, of course, many sub sections, such as you can trade on behalf of clients (Sales division) or on behalf of the bank (proprietary trading).

There are also specifications within trading, commodities/equities/forex and the 'way' you trade: day trading, fundumental vs technical and so on.

I will tell you a couple of things about this kind of job.

a) It is very competitive and hard. Don't think you can do it "because I am good under stress" or because "you like competitive jobs". You need to be genuinely superior to be able to be good.
I will not judge you, but you need to be honest with yourself. Is there something you are "BEST" at. Maths or physics or anything, have you ever had a niche for thinking logically and much faster than your friends/fellow students? If the answer is not, you're unlikely to succeed or even get past the first stages. Just effort is not enough

b) The job itself is very stressful. Especially trading. You do need to be very good under pressure. You must realise that this job will take a lot from you. It will be hard, stressful, competitive and ruthless, but so far it has 'paid' well.

c) Lastly - the industry. Well it's not doing all that well. I personally don't think that you are going to see the profits in banking that we have seen in the last few decades. Trading has a lot of bonuses - but even those are being heavily attacked. Just google "bonus cap banking in US/UK".
In addition with all the incoming and already implemented regulations - not many people are hiring. Which only means you really need to be exceptional to succeed.

In conclusion: ask yourself, is it really something you want?

If you are absolutely fascinated by the idea of being in a very competitive and dynamic job market and you consider yourself very intelligent and you're confident - go for it.

MACD vs Stochastic? Which one is better/ are these the two best indicators?

Macd is amazing and gets great results. I have hear the same about stochastic. Any experiences of these two in forex trading.

Answer
there is no "best" magic bullet indicator....they all on occasion lie to you....If you like Stochastics (fast or slow) and MACD....then use BOTH....when they are both positive it could be a buy...if both negative it is probably a sell and when mixed...there is no consensus.

Myself on stocks I take a consensus of about 8 indicators and 4-5 overlays before I make a decision... it is usually a good decision this way.
