Demand > supply = price increases, demand < supply = price decreases. We all know that the laws of supply and demand set prices. This rule also applies to stock trading; however, there is a high probability of error when using this rule to judge the volume balance of buy/sell stocks in the limit order book. The key factor is the ‘remaining volume (balance).’ The volumes of stocks listed on the limit order book are meant for trading, but traders can manipulate some of the specified prices for illegal purposes. Additionally, in an uptrend, the seller submits a higher price, and the transaction is not executed immediately. Conversely, in a downtrend, the buyer sets a price to buy at a lower price, allowing the unsold balance to accumulate. In the limit order book, the principle works in reverse. Of course, it cannot be applied 100% in every case. - Joseph’s “just my thoughts”

Vaccines have allowed people to travel worldwide. Migration and population density are benefits of vaccines. When vaccines failed to curb the epidemic, the “space” ultimately addressed the epidemic. This history is why maintaining “social distance” is essential. Hunting requires one million square meters to secure a person’s livelihood, but urbanization restricts many individuals from accessing such vast spaces. On the other hand, if agriculture can address livelihood needs with just 500 square meters, and its efficiency can increase by 2,000 times, then the perspective on the epidemic reveals insights about civilization. - Joseph’s “just my thoughts”

Architecture has developed in response to the epidemic. The city was designed to mitigate the risk of outbreaks. However, its high population density renders it susceptible to epidemics. A potential solution to this issue involves the construction of a water supply and sewage system, which safeguards individuals from waterborne infectious diseases (e.g., cholera) by effectively separating and burying water and sewage underground. Nonetheless, the advent of vaccines has facilitated the existence of megacities with populations exceeding 10 million people. Indeed, microorganisms predominantly populate the Earth. - Joseph’s “just my thoughts”
