Most major U.S. brokers now offer $0 commissions on online ETF trades. Confirm this so you aren’t losing money to fees on every transaction.

Most ETFs pay dividends. You can choose to have these paid out as cash or set up a DRIP (Dividend Reinvestment Plan) to automatically buy more shares.

Look at the "Bid" (the highest price a buyer is willing to pay) and the "Ask" (the lowest price a seller is willing to accept). The difference is the spread . Choose an Order Type:

Unlike mutual funds, which only price once at the end of the day, ETF prices fluctuate every second the market is open.

Buys the ETF immediately at the best available current price.

Once your account is funded, the process is similar to buying a single stock.

You set a specific maximum price you are willing to pay. This is highly recommended for ETFs to avoid "price spikes."

Again, use a Limit Order to ensure you receive the price you expect.
