See if you smart:
At 0919 how is he making the arm move up or down?

he's got his foot on top of the guys foot under the table and puts pressure on it when he says ''do you feel the pressure''
Off course they are smart that's why they are surviving in the market.
Anyone know maths?
If so I'm stuck on this question
Given that the volume of a cylinder is pi times radius squared times height,
And that the volume of a sphere is 4/3 times pi times radius cubed.
A cylinder with diameter 10cm, Height 20cm, Half full with water (at 10cm).
3200 ball bearings are added and now the water is 18cm high.
What is the radius of 1 ball bearing?
Thought this was as good a place as any to ask!
Would I be right in thinking the volume of 1 ball bearing is 1/16pi?
why?
Re: well? are traders smart?
Thought would ask here before signing up to yet another forum
i dont know but thought you were more likely to find the answer on an Alevel maths or phys website
why?
Assuming all spheres get underwater, I got r = 0.36cm, dont think you should have pi in the answer
Change in volume of fluid = volume of spheres added
pi*(5^2)*8 = 3200*(4/3)*pi*(r^3) then solve or r?
The primary reason for the failure of the vast majority of "traditional" High IQ traders is that they lack a high "emotional" IQ or E-IQ. A so-called genius level E-IQ is extremely rare and it is the highest attribute of long term successful traders.
A fraction of a percent of active traders have this attribute. A heuristic to determine a high E-IQ is the ability to remain focused and calm during times of high anxiety. High E-IQs do not anger and are impossible to provoke. These on the ones whom exceed the "Right Stuff" standard.
I would feel extremely confident that there is not a single member or contributor on this site which possesses an E-IQ at this level. It is not difficult to master puzzles and standardize testing problems with enough practice and short cut solutions, but emotional intelligence is like an artistic ability. Some can draw or sing but most can't draw a circle or carry a tune. Here is a test: if you are extremely good at solving any mathematical problem and you are the master of any analytic reasoning scenario but you have little patience for those whom you feel are not as intellectual as you are... you may need more work on you E-IQ and it is highly likely that as a trader you will suffer a terminal draw down at some point.
To put it in terms you will understand; Hubris will doom all "smart" traders.
I'll be the first to say i dont have the E-IQ for trading. I guess i should stop making 50%+ a year.
Are you bragging or complaining?
