The bone knifeIn this article, we're going to talk about how to use the main function to refer to something. For example, let's say you open a contract for BTC_USDT quarterly at $30,000, how should you write it? Live to explain the main function. var info = $.OpenLong ((exchange, "quarter", 100) is the name of the So what does exchange 100 represent?
High suction low throwSlidePrice should ideally be a price-to-earnings ratio.
Inventors quantify - small dreams$0.OpenLong ((exchange, "quarter", 100) is a free exchange. The exchange is the object of this exchange, Kido, a quarterly contract, 100 pieces.
Inventors quantify - small dreamsHigh frequency suggests writing a separate trading mechanism, which has some transaction residual detection, which can be time consuming. High frequency suggests customizing the trading logic directly.
High suction low throwI'm using this OpenLong DOT ((4 knives), give me a list of 9 knives ((4+5).
Inventors quantify - small dreamsNo, it's a slip price, a little extra for one meal.
