Advice for stirring your online community and fostering engagement
When you enter into any new area of science, you almost always find
yourself with a baffling new language of technical terms to learn before you can converse with the experts. This is certainly true in astronomy both in terms of terms that refer to the cosmos and terms that describe the tools of the trade, the most prevalent being the telescope. So to get us off of first base, let’s define some of the key terms that pertain to telescopes to help you be able to talk to them more intelligently. The first area of specialization in telescopes has to do with the types of telescopes people use. The three designs of telescopes that most people use are the Refractor, the Reflector and the Schmidt Cassegrain telescope. The refractor telescope uses a convex lens to focus the light on the eyepiece. The reflector telescope has a concave lens which means it bends in. It uses mirrors to focus the image that you eventually see. The Schmidt Cassegrain telescope uses an involved system of mirrors to capture the image you want to see. A binocular telescope uses a set of telescopes mounted and synchronized so your view of the sky is 3-D. Beyond the basic types, other terms refer to parts of the telescope or to the science behind how telescopes work. Collimation is a term for how well tuned the telescope is to give you a good clear image of what you are looking at. You want your telescope to have good collimation so you are not getting a false image of the celestial body. Aperture is a fancy word for how big the lens of your telescope is. But it’s an important word because the aperture of the lens is the key to how powerful your telescope is. Magnification has nothing to do with it, its all in the aperture.

국외선물이란?
다양한 정보를 참고하세요.
해외선물은 해외에서 거래되는 파생상품 중 하나로, 지정된 기반자산(예: 주식, 화폐, 상품 등)을 바탕로 한 옵션계약 약정을 말합니다. 본질적으로 옵션은 특정 기초자산을 향후의 어떤 시점에 일정 가격에 사거나 팔 수 있는 자격을 허락합니다. 국외선물옵션은 이러한 옵션 계약이 해외 시장에서 거래되는 것을 지칭합니다.
외국선물은 크게 콜 옵션과 풋 옵션으로 분류됩니다. 콜 옵션은 특정 기초자산을 미래에 일정 가격에 매수하는 권리를 제공하는 반면, 풋 옵션은 명시된 기초자산을 미래에 일정 가격에 팔 수 있는 권리를 허락합니다.
옵션 계약에서는 미래의 특정 일자에 (만기일이라 칭하는) 일정 가격에 기초자산을 사거나 팔 수 있는 권리를 보유하고 있습니다. 이러한 금액을 행사 금액이라고 하며, 종료일에는 해당 권리를 실행할지 여부를 선택할 수 있습니다. 따라서 옵션 계약은 투자자에게 미래의 가격 변화에 대한 안전장치나 수익 창출의 기회를 허락합니다.
국외선물은 마켓 참가자들에게 다양한 투자 및 매매거래 기회를 열어주며, 외환, 상품, 주식 등 다양한 자산군에 대한 옵션 계약을 포괄할 수 있습니다. 거래자는 풋 옵션을 통해 기초자산의 하향에 대한 안전장치를 받을 수 있고, 매수 옵션을 통해 상승장에서의 수익을 노릴 수 있습니다.
국외선물 거래의 원리
실행 금액(Exercise Price): 국외선물에서 실행 금액은 옵션 계약에 따라 명시된 가격으로 약정됩니다. 종료일에 이 가격을 기준으로 옵션을 행사할 수 있습니다.
만기일(Expiration Date): 옵션 계약의 만기일은 옵션의 실행이 불가능한 마지막 날짜를 뜻합니다. 이 날짜 이후에는 옵션 계약이 소멸되며, 더 이상 거래할 수 없습니다.
매도 옵션(Put Option)과 콜 옵션(Call Option): 풋 옵션은 기초자산을 특정 가격에 팔 수 있는 권리를 부여하며, 콜 옵션은 기초자산을 지정된 금액에 매수하는 권리를 부여합니다.
계약료(Premium): 해외선물 거래에서는 옵션 계약에 대한 옵션료을 지불해야 합니다. 이는 옵션 계약에 대한 비용으로, 시장에서의 수요와 공급량에 따라 변화됩니다.
행사 방식(Exercise Strategy): 투자자는 종료일에 옵션을 실행할지 여부를 선택할 수 있습니다. 이는 시장 환경 및 투자 전략에 따라 상이하며, 옵션 계약의 이익을 최대화하거나 손실을 최소화하기 위해 결정됩니다.
시장 위험요인(Market Risk): 외국선물 거래는 시장의 변화추이에 영향을 받습니다. 가격 변화이 기대치 못한 방향으로 일어날 경우 손실이 발생할 수 있으며, 이러한 마켓 리스크를 최소화하기 위해 투자자는 계획을 구축하고 투자를 설계해야 합니다.
골드리치와 함께하는 외국선물은 안전하고 확신할 수 있는 운용을 위한 최적의 대안입니다. 고객님들의 투자를 지지하고 인도하기 위해 우리는 최선을 다하고 있습니다. 함께 더 나은 내일를 지향하여 전진하세요.
