Dynamics of Forex Trading- Explained By Trade Expert, Barry Sendach

Forex also known as Forex exchange or FX is the world’s most widely traded market turning over $4 trillion each and every day. FX traders try to profit from fluctuations in the exchange rates between currencies, speculating on whether the currency’s value will go up or down in relation to another pair for example- USD/CHF. If the pair of US dollar and Swiss Franc blooms up, the trader will receive profit otherwise loss.

What makes the FX market so attractive to traders is its high liquidity and dynamic nature. Unlike other markets, Forex trading is not restricted to physical exchange hours, as the market is open 24 hours a day. At any given time traders worldwide are active creating an agile marketplace capable of responding quickly to local or global events.

According to Forex trade expert, Barry Sendach, exchange rates are affected by whole host of factors, with few considerations being-

  • Economic forecasts and results

  • Monetary policy

  • Global political events

  • Natural disasters

According to Barry Sendach opinion all of this means that there are plenty of opportunities for trading on the FX market. Traders can take up or close multiple positions quickly thanks to the fast pace and unrivalled popularity of the market and the internet. In the past decade, many investors have started investing in the Forex market after the unexpected crash of stock market. It seems like it is lucrative opportunity to earn profits tried by traders. But the matter of fact is that most of the currency investors don’t know that they can invest on gold too. Global gold trading is far more safe and simple way to earn money as compared to currency exchange due to the fact that it is less risky and you can sell it anywhere in the world with expert advice of Barry Sendach.

Liquid crystal bubbles experiment arrives at International Space Station

Boulder CO (SPX) Apr 23, 2015
An experiment led by the University of Colorado Boulder arrived at the International Space Station today and will look into the fluid dynamics of liquid crystals that may lead to benefits both on Earth and in space. A new physical science investigation on ISS, the Observation and Analysis of Smectic Islands in Space (OASIS), will examine the behavior of liquid crystals in microgravity, sai

[ Abstract ]
Considerations of local atomic level stresses associated with each atom represent a particular approach to address structures of disordered materials at the atomic level. We studied structural correlations in a two-dimensional model liquid using molecular dynamics simulations in the following way: We diagonalized the atomic level stress tensors of every atom and investigated correlations between the eigenvalues and orientations of the eigenvectors of different atoms as a function of distance between them. It is demonstrated that the suggested approach can be used to characterize structural correlations in disordered materials. In particular, we found that changes in the stress correlation functions with decrease of temperature are the most pronounced for the pairs of atoms with separation distance that corresponds to the first minimum in the pair density function. We also show that angular dependencies of the stress correlations previously reported in [Phys. Rev. E v.91, 032301 (2015)] are not related to the alleged properties of the stress field, but are a trivial consequence of the rotational properties of the stress tensor.


Charybdis by William Pye is an installation with a spinning vortex that can be observed from multiple levels.

About the piece:

The sirens Charybdis and Scylla resided in the Sicilian Sea. Homer tells us that because Charybdis had stolen the oxen of Hercules, Zeus struck her with a thunderbolt and changed her into a whirlpool whose vortex swallowed up ships. In Charybdis the circular movement of water inside a transparent acrylic cylinder forms an air-core vortex in the centre. Steps wrap around the cylinder and allow spectators to view the vortex from above. 

How it works:

An air-core vortex is generated within a circular dish. Water rises and falls within the dish in a cyclic program of water activity. When the system is full and flowing over the perimeter and down the sides, the top surface is comparatively flat and smooth, only broken by the vortex in the middle. However, as the level drops, the body of water seems to take on a life of its own, increasingly rocking and swaying as its volume diminishes unaided by any outside force.
