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.

Azas Black (Hukum Kekekalan Energi Untuk Kalor)

Mungkin Anda pernah menciptakan teh anggun dan terlalu panas. Agar sanggup diminum maka harus didinginkan terlebih dahulu. Untuk mendinginkan cukup menambahkan air masbodoh atau es kedalam teh tersebut. Kejadian menurunkan suhu zat yang suhunya tinggi dengan cara mencampurkan zat yang suhunya rendah ternyata sangat sesuai dengan konsep fisika.

Setiap dua benda atau lebih dengan suhu berbeda dicampurkan maka benda yang bersuhu lebih tinggi akan melepaskan kalornya, sedangkan benda yang bersuhu lebih rendah akan menyerap kalor sampai mencapai keseimbangan ialah suhunya sama. Dalam sistem terisolasi, pelepasan dan peresapan kalor ini besarnya imbang. Sejumlah kalor yang hilang dari zat yang bersuhu tinggi sama dengan kalor yang didapat oleh zat yang suhunya lebih rendah. Kalor yang dilepaskan sama dengan kalor yang diserap sehingga berlaku hukum kekekalan energi. Pada sistem tertutup, kekekalan energi panas (kalor) ini sanggup dituliskan sebagai berikut.

Qlepas = Qterima

Persamaan tersebut berlaku pada pertukaran kalor, yang selanjutnya disebut Asas Black. Hal ini sebagai penghargaan bagi seorang ilmuwan dari Inggris berjulukan Joseph Black (1728 - 1799). Pertukaran energi kalor merupakan dasar teknik yang dikenal dengan nama kalorimetri. Untuk melaksanakan pengukuran kalor yang diharapkan untuk menaikkan suhu suatu zat dipakai kalorimeter. Salah satu kegunaan yang penting dari kalorimeter yakni untuk  mengukur kalor jenis suatu zat.
Mungkin Anda pernah menciptakan teh anggun dan terlalu panas Azas Black (Hukum Kekekalan Energi Untuk Kalor)
Kalorimeter sederhana
Untuk memantapkan pemahaman Anda wacana aturan kekekalan energi untuk kalor, silahkan simak pola soal di bawah ini.

Contoh Soal 1
50 gr air dengan suhu 20°C dicampur dengan 100 gr air teh bersuhu 80°C. Berapakah suhu simpulan gabungan sesudah terjadi kesetimbangan termal?

Penyelesaian:
mair = 50 gr
Tair = 20°C
mteh = 100 gr
Tteh = 80°C

Qlepas = Qterima
mteh.cteh.ΔT = mair.cair.ΔT
karena kalor jenis air sama dengan kalor jenis air teh maka persamaannya menjadi:
mteh.(Tteh – T) = mair.(T – Tair)
100.(80 – T) = 50(T – 20)
8000 – 100T = 50T – 1000
9000 = 150T
T = 9000/150
T = 60°C

Contoh Soal 2
Air bermassa 300 gr  dengan suhu 4 °C dicelupkan besi 2000 gr dengan suhu 90 °C. Jika kalor jenis air = 1,0 kal/gr°C dan kalor jenis besi = 0,10 kal/gr°C, maka tentukan suhu kesetimbangannya!

Penyelesaian:
mair = 300 gr
Tair = 4°C
cair = 1,0 kal/gr°C
mbesi = 2000 gr
Tbesi = 90°C
cbesi = 0,10 kal/gr°C

Qlepas = Qterima
mbesi.cbesi.ΔT = mair.cair.ΔT
2000.0,1.(90 – T) = 300.1,0.(T – 4)
18000 – 200T = 300T – 1200
19200 = 500T
T = 19200/500
T = 38,4°C

Contoh Soal 3
Dalam gelas berisi 200 cc air 40 °C kemudian dimasukkan 40 gram es – 10 °C. Jika kapasitas kalor gelas = 20 kal/°C, kalor jenis air =  1 kal/gr°C, kalor jenis es = 0,5 kal/gr°C, dan kalor lebur es = 80 kal/gr, maka berapakah suhu seimbangnya?

Penyelesaian:
mair = 200 gr
Tair = 40 °C
Cgelas = 20 kal/°C
Tgelas = Tair
mes = 40 gr
cair = 1 kal/gr°C
ces = 0,5 kal/gr°C
Tes = – 10 °C
Les = 80 kal/gr

Dari massa dan suhu air dibandingkan dengan massa dan suhu es sanggup diprediksikan bahwa suhu simpulan gabungan akan melebihi 0 °C. Pada proses tersebut kalor yang diterima sebagai berikut.
Qterima = mes.ces.ΔT + mes.Les + mes.cair.ΔT
Qterima = 40.0,5.10 + 40.80 + 40.1.(T – 0)
Qterima = 200 + 3200 + 40T
Qterima = 3400 + 40T

Sedangkan kalor yang dilepaskan sebagai berikut.
Qlepas = Cgelas.ΔT + mair.cair ΔT
Qlepas = 20.(40 – T) + 200.1.(40 – T)
Qlepas = 800 – 20T + 8000 – 200T
Qlepas = 8800 – 220T

Pada proses tersebut berlaku azas Black sebagai berikut.
Qterima = Qlepas
3400 + 40T = 8800 – 220T
40T + 220T= 8800 – 3400
260T = 5400
T = 20,8°C
