WTI 원유 선물 가격의 급격한 변화가 있던날

 WTI 관련된 선물 레버리지와 인버스의 가격이 정말 미친 것처럼 변한 하루였다.
 레버리지는 하한가로 떨어져 버렸고, 인버스는 상한가로 튀어 올랐다.
 레버리지 ETN은 심각한 괴리율로 거래정지 상태였는데, 다행인지 불행인지 감도 오지 않는다. 4월 28일 정도에 거래가 다시 된다고 하던데, 걱정부터 앞선다.

 오전 장은 KODEX WTI 인버스와 삼성 WTI 인버스 사이의 방향성이 반대로 감지 되는 상황이었다. 크게 반전 가능한 신호라고 판단되어 레버리지 매수를 진행 하였다.
 그러나, 오후 장으로 넘어가면서 모두 상한가로 향하면서 방향성의 괴리 신호는 의미가 없어져 버렸다. 이것은 내일도 원유의 가격이 하락으로 향할 가능성이 높다고 해석해도 될듯하다.

  기존에 두가지 지표의 방향성 분석을 해보면, 2월 25일 서로 다른 방향성을 보였다.
 이후 10일정도 경과후에 큰폭의 원유 하락이 시작 되었다.
  이때 기관은 25일 인버스 매수를 평소보다 눈에 띄게 큰 폭으로 매수를 진행 하였고, 10일 후 레버리지를 매우 큰폭으로 매도 하였다.
 분명 두 지표의 방향성 괴리는 시장의 혼란을 의미하고, 이것은 곧 큰 방향으로의 전환 가능성을 시사하는 것이다.

 매매의 성공을 위해서는 반드시 선행지표를 찾아서 올바르게 해석해야 한다.

Plasma discharge device, RF cable heating problem

Plasma used for thin film production in vacuum deposition equipment, etching equipment, etc.  And, among the many powers used to generate plasma, the most common 13.56MHz RF power.  We are applying RF power plasma devices in quite a lot of fields such as semiconductors, displays, etc.  RF power plasma devices are more complicated than regular DC plasma devices and require a matching network. However, it can be used in insulators, and the surface properties of thin films are often improved, so RF is often used.  There are many things to consider about these RF discharge plasma devices, but today, I want to write about the heat generation problems that occur in RF cables.  The RF plasma discharge device consists of an RF power supply, an impedance matcher (matching network) for effectively delivering power to the load, and a discharge load device.  RF power requires an understanding of impedance. Impedance is an amount that defines the correlation between voltage and current. In DC, resistance becomes impedance. It becomes complicated in AC power, and when it takes up this and that complex understanding, there are real resistance and imaginary resistance. From the plasma point of view, the real resistance is related to the amount of absorbed power (density and quality of plasma), and the imaginary resistance is the amount independent of power consumption (the amount that is not consumed and reflected) and the supplied energy. You can think of it as saving. The role that is stored in this way is a complicated explanation, and it is most often caused by heat, and we recognize the heating line. Most of the time, there is a problem.  After all, RF power requires impedance matching to reduce this heat generation problem. Being a fever means that there is a problem with matching, and that power transmission is not efficient for the load (power loss).
To reduce power loss, plasma density and quality must be improved. It is necessary to check various process conditions in consideration of discharge characteristics. The next method is to reduce the actual resistance of the line. It is good to minimize each fastening part of the conducting wire and apply coating or silver plating to prevent surface oxidation. Also, the thickness of the line should be considered. If it is difficult to solve the thickness of a line, multiple lines in parallel can be a method. Finally, there is a method to increase the effective real resistance, which can be suppressed by increasing the voltage and decreasing the current. However, if the balance is not balanced, adverse effects will occur, and additional problems such as arcing should be considered.  In some cases, there is a problem caused by the parasitic capacitance, which induces heat generation when matching occurs in the form of shaking or noise. There is a need for a technique to configure the system so that the resonant circuit is not constructed.  If continuous heat generation is not resolved in the delivery of RF power, it is necessary to consider distributing and supplying current. One solution is to reduce the current by configuring transmission lines in parallel.  In the case of ICP, the antennas may be configured in parallel to distribute current.
