Investing and trading are two very different methods. Investopedia’s definition:
The goal of investing is to gradually build wealth over an extended period of time through the buying and holding of a portfolio of stocks, baskets of stocks, mutual funds, bonds and other investment instruments
Trading, on the other hand, involves the more frequent buying and selling of stock, commodities, currency pairs or other instruments
Freetrade as a name comes from the trades (orders) being free. The product is more optimised for investing.
