Forex trading

No sane person would jump into the forex market blindly. You might as well set your money on fire if that’s what you’re going to do. Sensible investors study the market carefully first, learn the ins and outs of currency trading -- and even then, before they launch into it, they devise a smart forex trading strategy.

The market is constantly changing and is not always predictable, true. But you still require a scheme, one that provides for unknowns and surprises.

Your strategy should begin with how much money you can afford to lose. That may sound like a negative outlook -- after all, the goal is to MAKE money, not lose it -- but common sense tells you that the forex market is a gamble. There are precautions you can take that will make you less likely to lose your initial investment, but there’s no way to guarantee it. Your strategy must provide the possible action that you will take a bath, and for that cause you should never invest more than you are able to afford to lose.

Another good tip for your forex trading strategy is to avoid putting all your investments in one currency. What’s the old saying about eggs and baskets? Yeah, don’t put ‘em all in one. Spreading them out makes it much, much less likely that you’ll be wiped out, the way you would if you relied on one currency and it bottomed out.

As you develop your trading strategy, make yourself mindful of what the market is behaving like right now. Is it trending upward, or downward? What’s the general mood among traders? They all have a strategy, too, and are eager to know what others are thinking.

Consider also what your timeline is. How long do you want to stay in the market before taking your profits and getting out?

Your strategy must also involve learning the timing of the business. Timing is everything: Too late or too early and your potential profit evaporates. As you learn to gauge the market and make trades at just the right time, your profits will increase. A good strategy will factor in this learning curve and allow for a few mistakes at first.

Above all, to prepared to accept surprises when it comes to forex trading. Strategy can only get you so far. The rest is ingenuity and a little bit of luck.

Circular Motion - Cyclist on banked curve

acceleration around a banked curve?

A curve of radius 64m is banked for a design speed of 84km/hr . If the coefficient of static friction is 0.28 (wet pavement), at what range of speeds can a car safely make the curve? Consider the direction of the friction force when the car goes too slow or too fast.

Recall the following pair of equations from my earlier analysis:
N*cos(theta) = m*g + F*sin(theta)
N*sin(theta) + F*cos(theta) = m*v_max^2/r

These equations correspond to the situation of maximum speed of travel.

Substitute F = mu_s*N for maximum deliverable traction force:
N*cos(theta) = m*g + mu_s*N*sin(theta)
N*(sin(theta) + mu_s*cos(theta)) = m*v_max^2/r

Solve for N:
N*(cos(theta) - mu_s*sin(theta)) = m*g

Thus:
N = m*g/(cos(theta) - mu_s*sin(theta))

Substitute:
m*v_max^2/r = m*g*(sin(theta) + mu_s*cos(theta))/(cos(theta) - mu_s*sin(theta))

Cancel dependence on m:
v_max^2/r = g*(sin(theta) + mu_s*cos(theta))/(cos(theta) - mu_s*sin(theta))

Solve for v_max:
v_max = sqrt(r*g*(sin(theta) + mu_s*cos(theta))/(cos(theta) - mu_s*sin(theta)) )

- - - - - - - - - - - - - -
For minimum speed of travel, friction acts in the opposite direction (up along the asphalt):
N*cos(theta) = m*g - F*sin(theta)
N*sin(theta) - F*cos(theta) = m*v_min^2/r

Perform similar algebra to eventually solve for v_min:
(CAUTION: N and F are not the same as in the maximum speed case)
N*cos(theta) = m*g - mu_s*N*sin(theta)
N*(sin(theta) - mu_s*cos(theta)) = m*v_min^2/r

N*(cos(theta) + mu_s*sin(theta)) = m*g
N = m*g/(cos(theta) + mu_s*sin(theta))

m*g*(sin(theta) - mu_s*cos(theta))/(cos(theta) + mu_s*sin(theta)) = m*v_min^2/r
g*(sin(theta) - mu_s*cos(theta))/(cos(theta) + mu_s*sin(theta)) = v_min^2/r

v_min = sqrt(r*g*(sin(theta) - mu_s*cos(theta))/(cos(theta) + mu_s*sin(theta)) )

Summary:
v_max = sqrt(r*g*(sin(theta) + mu_s*cos(theta))/(cos(theta) - mu_s*sin(theta)) )
v_min = sqrt(r*g*(sin(theta) - mu_s*cos(theta))/(cos(theta) + mu_s*sin(theta)) )

Note: if you end up with an imaginary number or zero for v_min, it means that all speeds are safe.
If you end up with an imaginary number or zero for v_max, it means that no speed is safe.

What is theta? Well, recall the formula for the design of banking angle we derived in the other problem:
theta = arctan(v_proper^2/(r*g))

Substitute this in to each formula for maximum and minimum speed, and do much simplification:
v_max = sqrt(r*g*(v_proper^2 + mu_s*r*g)/(r*g - mu_s*v_proper^2))
v_min = sqrt(r*g*(v_proper^2 - mu_s*r*g)/(r*g + mu_s*v_proper^2))

Data (notice the unit conversion):
v_proper:=70/3 m/s; g:=9.8 N/kg; r:=64 m; mu_s:=0.28;

Results:
v_max = 30.84 meters/second
v_min = 17.23 meters/second

And if you prefer kilometers/hour, simply translate:
v_max = 111 km/hr
v_min = 62.1 km/hr

We have to round in the interest of safety.
