This article is aimed at answering common questions about novices for program trading. For novices who do not know programming, quantification, or even trading, it is difficult to learn quantification at the beginning. This article will introduce some of the most basic concepts.

1. What is digital currency program trading?

Program trading is to use a program to connect with the exchange through API to automatically trade Bitcoin or achieve other functions according to the design intent. Program trading is not the same as quantitative trading. You can also realize some auxiliary functions, such as price alarm, data statistics, automatic full position, regular buying, and set price buying and selling. Obtaining profits from program trading is a more difficult task.

2. Why is it necessary to conduct program automatic trading?

  • Program unattended, it has more advantages in the face of 7 * 24 digital currency trading market.
  • Manual operation of high-frequency strategy is unrealistic, and only automatic trading procedures can be used.

3. What are API and API-KEY?

The full name of API is Application Programming Interface. You can see the words "API" in the corners of each exchange. Click it, and you can see the corresponding documents. It is clear at a glance which functions can be implemented, such as Okcoin API documents.
The apiKey and secretKey are account passwords, which are not required for all connections, such as viewing historical transaction records, obtaining tickers, in-depth data and other public information; It is necessary to view account information, order transactions, etc. Generally, keys can be applied in the user center. After the key is received, it should be saved and cannot be disclosed.
API protocols usually include REST API and WebSocket. The REST API interacts once every connection, while WebSocket can realize subscription, such as subscription account information. When account data changes, account information will be pushed, while REST needs to request it by itself. Both of them are very common and you can select according to the actual situation of the strategy.

4. In which exchange did you trade in 2019?

OKX, Huobi and Binance are generally recommended. These three exchanges are relatively good, deep and active. If other exchanges have no special needs, they will not be considered. Small platforms have high risks and poor liquidity, which is not conducive to trading. For futures trading, the risk is very high. Novice is not recommended.
