Stock Trading: The Basics

Stock trading or share trading is a method of investment that prioritizes immediate gains over enduring profits. It can be hazardous to bump into the stock market without prior knowledge of how things work in this field.

Active trading is where a stakeholder or depositor places more than 10 trades on a monthly basis with a strategy of making a profit on a short-term or temporary basis.
