Your first share or fund order: broker, custody, order types, costs

To buy a share or a fund, you open an account with a regulated brokerage, add money, and place an order. The broker sends your order to an exchange, and your holdings are recorded in your name with a custodian, separate from the broker's own money.

This guide walks through checking a broker, opening the account, the three order types you will meet, and what each order really costs.

Who does what when you buy

Several parties stand between you and the market. Knowing who does what tells you who to ask when something goes wrong.

Often your broker, or a bank it works with, acts as custodian. Your account agreement says who holds your assets and how dividends reach you. Read that part before you sign.

Step 1: check the broker is regulated

Every country has a securities regulator, and most keep a public register of firms allowed to deal with the public. Search it by the firm's legal name, which can differ from the app's brand name. Many regulators also publish warning lists of unlicensed firms.

Next, check whether an investor-protection scheme covers the firm. These schemes step in if a broker fails and client assets go missing. They do not cover market losses. Two examples, as of October 2026:

Your country's scheme, if it has one, will have its own limits. A broker licensed abroad may fall under that country's scheme, not yours.

Step 2: open the account

Most brokers open accounts online. Expect three parts.

1. Identity checks (KYC). An ID document, proof of address, and often your tax number.
2. Questions about you. Your income, experience and goals. Firms use them to decide which products you may trade.
3. Agreements. The terms of business, the custody terms and the fee schedule. Save copies.

Some countries offer tax-advantaged investment accounts. Ask whether the broker offers one before you open a plain taxable account.

Step 3: add money and read your balance

You transfer money from your bank. Your app will often show two kinds of cash:

• Buying power: money you can use to buy now.
• Settled or withdrawable cash: money that can go back to your bank.

After you sell, the trade must settle before the cash is fully yours. In the United States, the standard cycle for most trades moved from two business days to one (T+1) on 28 May 2024, the SEC says. Other markets differ, so check your broker's help pages.

Step 4: choose an order type

These descriptions follow FINRA's guide to order types (October 2026).

A stop-limit order turns into a limit order at the trigger instead. You control the price but may not get a fill.

Step 5: know what each order costs

Four costs can apply. Not every broker charges all of them.

Taxes on trades and gains depend on your country. Check your tax authority's guidance before you sell.

Worked example: one round trip of $2,000

All numbers here are examples, not quotes. You buy $2,000 of a fund that trades in a different currency from your account. Commission is $1 per order. The spread is 0.2%, so each side costs half of it (0.1%). The FX fee is 0.5% each way.

Check: 2,000 × 0.001 = 2, and 2,000 × 0.005 = 10. One round trip costs $26, or 1.3% of $2,000. The fund must rise 1.3% before you break even, and the FX fee is the largest part. Buying in your own currency, or in larger and rarer orders, can cut it.

Fractional shares

Some brokers let you buy part of a share, so you can invest a set amount. FINRA (June 2025) notes that you usually can't move fractional shares to another broker without selling them first. You may also get no voting rights, and some firms bundle fractional orders, which can affect your price.

Step 6: place the order and check the result

1. Search by name or ticker, and check the exchange and currency are the ones you meant.
2. Choose buy, then the amount or number of units, then the order type.
3. Read the preview: total value, estimated fees and any FX conversion.
4. Confirm, then check whether the order shows as filled, partly filled or pending.
5. Save the trade confirmation. It is your record of price, fees and date for tax.

Your plan

1. Write down why you are buying and for how long, before you open any app.
2. Check two or three brokers on your regulator's register, using their legal names.
3. Check the protection scheme that covers each one, and its limit.
4. Ask for each fee sheet and work out the cost of one $1,000 round trip, including FX.
5. Read the custody terms and note who holds your assets and how dividends are paid.
6. Start with a small limit order and see how the fill, fees and confirmation look.
7. Keep a log of every trade, with the date, price, fees and reason.

If you only want "the market", a broad index fund does that in one order.

What to watch out for

• Unregulated "brokers" and tip groups. If a firm is not on your regulator's register, don't send it money or your ID.
• Market orders in thin markets. You can pay far more than the last price you saw.
• Hidden FX costs. A small percentage on every buy and sell adds up fast.
• Margin offers. Borrowing to buy multiplies losses and can force a sale at the bottom.
• Small, frequent trades. Fees and spreads are charged on every trade, win or lose.
• Protection limits. Schemes cover a failed broker, not falling prices.
