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”
In business, capital means business funds. A successful entrepreneur often says, "I started my business without any capital". It's partly true, but it's a lie. The entrepreneur just said that capital means only cash. However, all kinds of businesses need to be fundamentally business funds in any even not cash. The entrepreneur didn't count the founder's labor cost. No inputs, no outcomes. The uncounted labor costs are called "alternative costs" or "opportunity costs". This comes from comparative advantage. If the entrepreneur doesn't accept the uncounted labor cost as a debt, the entrepreneur is equivalent to losing the profit due to opportunity costs. Please always remember this. There is no free lunch in this world. - Joseph’s “just my thoughts”
