Best Online Stock Trading Brokers for 2018 If you’re looking for a way to build more wealth in 2018, getting started with one of the best online brokerage accounts is a solid first step. Doing so will allow you to invest outside your traditional retirement accounts and on your own terms. The best part is, the best online brokerage firms charge little or no fees and offer excellent resources that can help you learn more about investing along the way. Of course, not all brokerage firms are created equal, and that’s why we took the time to break down each of their details and rank the top options on an array of factors. If you’re looking for a new way to invest this year and are ready to strike out on your own, the following online brokerage accounts should be at the top of your list.What Matters When You Trade Stocks on Your Own? Managing your own money can be a stressful endeavor. To minimize this, and to minimize information overload that tends to come from watching the markets 24/7, there are a few must-haves to look for in an online broker. Clean interface. When I trade, I want to be able to easily find my order entry ticket. I don’t want it buried under a number of drop downs. This interface should have intuitive access to see your balance, available cash, positions with real time P/L and all be easily navigated. Quick access to basic charting. A chart tells me where the stock has been recently. I don’t trade minute to minute anymore, so I don’t need complex tools like stochastics or retracement lines. All that’s important is that I have a basic chart on a yearly, monthly, weekly, daily and intra day time period. I use a chart to see current price relative to those time periods, mainly to avoid purchasing at a bad price. Low fees. One of the biggest roadblocks to building wealth is fees incurred to invest your hard-earned dollars. Because the fees charged by different brokerage firms vary so dramatically, it’s crucial to seek out options that charge low fees (or no fees) for account management and trades. There are over 50 online brokerages where you can open an account. Beyond the my three rules above, best online brokerage accounts aren’t just for trading stocks. Sure, many of them started as online stock trading accounts, but now they’re full-fledged trading, saving, investing, retirement planning, and banking machines. This industry is more complex than the average person thinks. You shouldn’t just pick any online broker and sign up for an account. The best online broker for one person is often completely different for the next person. Use this resource as a guide to your decision process. Figure out what features are best for you, and make your selection. What Makes a Great Online Broker? I analyzed a number of elements to come to my decision on which brokers are the best. Later in this post, I provide full details on how I selected the best online brokerages. When you take all the features, resources, trading platforms, and technology into account (while also considering every type of trader), the full-service brokers, like E*TRADE and TD Ameritrade are the best for the largest number of people. For those simply looking to make cheap trades, I would recommend going with Optionshouse. If you’re a very advanced trader, high-volume trader, or a professional who manages money, I recommend going with Interactive Brokers. However, I didn’t include Interactive Brokers on my list because they’re best for a very small group of traders and the platform is very complex. Top Qualities of Standout Online Trading Platforms Quality trading tools and technology Multiple trading platforms for all levels of traders Excellent mobile trading features Solid navigation that displays the relevant information where you want it Quality educational resources and research for trader development There’s more to selecting an online broker than price. You have to consider the resources you’re getting for the cost you pay per trade. For example, my colleague, who is also an ex-trader, likes to use a combination of stock and options trade in his longer-term trading. He recently switched over to Fidelity because he really liked the cash management features, but was very disappointed by complex order entry, sub-par options execution and frustrating navigation. He’s currently making the switch to one of the brokers I profile here.

Matahari Sebagai Pusat Tata Surya



Matahari merupakan salah satu bintang di dalam Galaksi Bima Sakti yang memiliki fungsi dan peranan paling penting di dalam struktur tata surya. Matahari merupakan kepingan dari tata surya yang memiliki ukuran, massa, volume, temperatur, dan gravitasi yang paling besar sehingga matahari memiliki imbas yang sangat besar pula terhadap bendabenda angkasa yang beredar mengelilinginya.

Matahari memiliki garis tengah sekitar 1.392.000 km atau sekitar 109 kali garis tengah bumi. Massa atau berat totalnya sekitar 332.000 kali dari berat bumi, volumenya diperkirakan 1.300.000 kali volume bumi, dan temperatur di permukaannya sekitar mencapai 5.000° C, sedangkan temperatur di pusatnya sekitar 15.000.000° C.

Temperatur matahari yang sangat tinggi menurut Dr. Bethe (1938) disebabkan oleh adanya reaksi inti di dalam tubuh matahari. Ia ber pendapat bahwa dalam keadaan panas dan tekanan yang sangat tinggi, atom-atom di dalam tubuh matahari akan kehilangan elektronelektronnya sehingga kemudian menjadi inti atom yang bergerak ke aneka macam arah dengan kecepatan yang sangat tinggi, dan mengakibatkan tumbukan antarinti atom dan penghancuran sebagian massanya (massa defect), kemudian berkembang menjadi energi panas dan cahaya yang dipancarkan ke aneka macam arah.

A. Struktur Matahari


Secara garis besar, struktur matahari dibagi menjadi tiga, yaitu atmosfer, fotosfer dan barisfer.

1. Atmosfer Matahari

Atmosfer matahari adalah lapisan paling luar dari matahari yang berbentuk gas, terdiri atas dua lapisan, yaitu kromosfer dan korona.

Kromosfer merupakan lapisan atmosfer matahari kepingan bawah yang terdiri atas gas yang renggang berwarna merah dengan ketebalan sekitar 10.000 km. Lapisan gas ini merupakan lapisan yang paling dinamis karena seringkali muncul tonjolon cahaya berbentuk lidah api yang memancar sampai ketinggian lebih dari 200.000 km yang disebut prominensa (protuberans).

Korona adalah lapisan atmosfer matahari kepingan atas yang terdiri atas gas yang sangat renggang dan berwarna putih atau kuning kebiruan, serta memiliki ketebalan mencapai ribuan kilometer.

Kromosfer dan korona dalam keadaan normal tidak mampu terlihat terperinci dari bumi karena tingkat sinar terangnya lebih rendah dari lapisan permukaan matahari. Atmosfer matahari (kromosfer, korona, dan prominensa) mampu terlihat terperinci jikalau bulatan matahari tertutup oleh bulatan bulan pada dikala terjadi gerhana matahari total atau melalui pengamatan dengan menggunakan alat yang disebut koronagraf.

2. Fotosfer Matahari

Permukaan (kulit) matahari disebut fotosfer. Dari sinilah datangnya sinar matahari yang mampu kita lihat dari bumi. Temperatur dari lapisan ini adalah 6.000 Kelvin. Permukaan fotosfer bukan merupakan suatu bidang rata, tetapi berbintik-bintik (berbutir-butir), yang disebut granulasi fotosfer.

Fotosfer matahari adalah lapisan berupa bulatan berwarna perak kekuning-kuningan yang terdiri atas gas padat bersuhu tinggi. Pada fotosfer matahari terlihat adanya bintik atau noda hitam berdiameter sekitar 300.000 km. Bahkan ada yang berdiameter lebih besar dari diameter bumi dengan kedalaman sekitar 800 km disebut umbra. Di sekeliling umbra, biasanya terdapat lingkaran lebih terperinci disebut penumbra. Noda-noda hitam pada matahari secara keseluruhan disebut sun spots.

Pada suhu mencapai 4.000 C, noda-noda matahari tampak gelap, lebih dingin, dan kurang cerah dibandingkan dengan kepingan lain dari fotosfer. Bagian dari nida matahari yang berwarna gelap disebut umbra dan yang berwarna lebih terperinci disebut penumbra.

3. Barisfer Matahari (inti matahari)

Inti matahari adalah kepingan dari matahari yang letaknya paling dalam, berdiameter sekitar 500.000 km dengan tingkat temperatur sekitar 15.000.000° C. Pada kepingan ini berlangsung reaksi inti yang mengakibatkan terjadinya sintesis hidrogen menjadi helium dengan karbon sebagai katalisatornya.

B. Pergerakan Matahari


Matahari tidaklah berada dalam keadaan statis, akan tetapi selalu bergerak dinamis baik individu maupun secara sistem. Adapun gerakan matahari secara garis besar terdiri atas gerak rotasi dan revolusi matahari.

1. Rotasi matahari 

Rotasi matahari adalah gerakan matahari berputar pada sumbunya yang berlangsung sekitar 25,5 hari di kepingan ekuator dan sekitar 27 hari di kepingan kutub matahari untuk satu kali putaran.

2. Revolusi matahari

Revolusi Mathari adalah gerakan matahari beserta anggota-anggotanya mengelilingi pusat galaksi Bima Sakti.

C. Peranan Matahari terhadap Kehidupan di Bumi


Matahari secara pribadi atau tidak pribadi merupakan sumber energi yang bermanfaat bagi kehidupan manusia. Sinar matahari yang sampai ke bumi hanya sekitar setengah milyar dari seluruh hasil energi matahari, hal ini disebabkan letak matahari yang sangat auh dari bumi.

Pengaruh matahari terhadap kehidupan insan di bumi antara lain, sebagai berikut:

1. Pengaruh sinar inframerah

Sinar inframerah sebagai salah satu spektrum cahaya matahari yang tidak kasat mata bahwasanya memiliki potensi dan imbas panas yang terbesar. Pengaruhnya terhadap kehidupan yaitu memiliki peranan pada terbentuknya siklus air di bumi (sinar inframerah menguapkan air laut, kemudian pada saatnya air maritim akan mengembun dan turun sebagai hujan).

2. Pengaruh sinar Ultraviolet

Sinar ultraviolet sebagai salah satu spektrum cahaya matahari yang tidak kasat mata bahwasanya memiliki potensi dan imbas kimia yang terbesar. Pengaruhnya terhadap kehidupan, antara lain:
  • Memiliki daya pembasmi terhadap bibit penyakit, terutama penyakit kulit.
  • Memberikan energi kepada tanaman untuk melakukan proses asimilasi.
  • Sebagai sumber provitamin D yang berfungsi untuk membantu pertumbuhan dan kesahatan tulang manusia.

3. Energi pancaran matahari sebagai sumber listrik

Energi pancaran matahari mampu diubah pribadi menjadi energi listrik, yang mampu dimanfaatkan untuk kepentingan hidup manusia.

4. Energi pancaran matahari sebagai sumber panas

Energi pancaran matahari mampu diubah pribadi menjadi energi kalor. Energi kalor mampu digunakan untuk memanaskan air yang memiliki kegunaan untuk mandi air hangat.
