“The market price is an outcome of collective dynamic gaming. In the battlefield of digital finance, API quantitative skills are a weapon. Learn some quantitative investment, and only by this will you know how to shoot with a gun.”
Quantitative investment is a way of investment by which modern scientific and technological methods come into function. During this process, to complete transactions, traders apply empirical knowledge derived from the historical data analysis. At present in the crypto market, quantitative investment is one of the mainstream investment strategies. Meanwhile, programming is still an insurmountable gap for junior individual investors who would love to get started.
This course, with a way easy to understand, is designed to accustom you to the basic operations and knowledge of API Quantitative Investment within 30 days. This may bridge you both to the crypto market and API quantitative method-applied traditional stock market!
Anyway, let’s get started~
I. What is API?
No matter what you work for and where you work in, I bet that you are fairly familiar with the term API, if not an expert of it. However, many people’s understanding of the API may still be vague. How can it help us without exactly knowing its function?
Of course, you may already have a clue if you excel in Googling any stuff. Finally, you got such stuff in your eyes:
Seeing this, students in art and humanities must get rattled! (╯‵□′)
Oh, Damn! Stop being a Shelton! Would you please speak in YOUR words?
Well, no problem! ⁄(⁄ ⁄•⁄ω⁄•⁄ ⁄)⁄
Let’s take an analogy. If you think of the exchange as a restaurant, the restaurant’s chef (programmer) offers a variety of dishes: top-ups, cash withdrawals, pending orders, withdrawals, quotes, and more. The API functions like the waiter in this restaurant. You just need to tell the waiter what you want to eat. After a while, the waiter will bring you the dishes.
Let’s abstract the above-mentioned scenario in a common statement: the API can be responsible for both receiving your instructions and returning the execution results of your given instructions.
Usually, we use products by logging into a page or switching on an app. In fact, you have sent an instruction to the provider (server) of the product service through the API.
For example, look at the following login page. When you click on “Login”, it means that you may have executed an instruction through an API. The content of the instruction is: You need to log in now.
“Logging in” indicates that the login API is executing the login command you sent.
After a while, the API will return the login command execution’s final result to you ↓↓↓
On the top right corner, it displays your account information, which notices that you have finished a successful login.
However, the exchange website or mobile app you are using now appears like a restaurant menu, which is prepared for guests who have no idea about the restaurant. The financial market has a very high demand for a qualified trade execution speed. Once any price fluctuation causes a bid-ask spread, one second only may induce your profit or loss. If we have learnt how to operate API directly, you may go ahead of the others. To make an analogy, it is like telling the waiter what food you want to eat while others are still watching the menu and squandering their time in hesitation!
II. What is Quantitative Investment?
At the earliest, the concept of quantitative investment was introduced to the public by Renaissance Institutional Equities Fund (RIEF) belonging to James Simmons (the grey-hair geezer shown below). In the past 20 years, Simmons’ Renaissance Technologies LLC has invested in the global market. They developed many mathematical models for trade and analysis, which basically operate in automated ways. They adopt computer programming to model the stock price, making trading and profiting easier.
Simmons once said: “Our commence is based on historical data on the market. We don’t think market prices should somehow develop any preconceived notion.”
Unlike Buffett’s value investment, Simmons believes that a deal is like a gecko: it should usually stay undynamic on the wall. Once the mosquito appears, gecko should eat it instantly and then calm down, waiting for the next opportunity.
The speed of human operation is limited. When investment opportunities arise, you need to spend more time and energy no matter how you call the trader or how you stare at the K line by yourself. Quantitative investment, however, means that as you’ve written your investment strategy based on historical data and experience, tireless machines can help you in swift executions at lowest costs.
Just as machine production gradually replaces manual labour, learning quantitative investment means that you have entered the industrial age from the manual era.
Since the first crypto exchange’s birth, it is still less than ten years. The quantitative crypto trade applied in the market is still in its emerging stage. So now, be ready to know more and seize the opportunities right at the corner!
