NordiqoStart with the pages nobody markets: terms of use, risk disclosure and the withdrawal policy. A platform comfortable with scrutiny publishes them in full instead of condensing them into three friendly bullet points.
Next, look at how returns are described. Wording matters: "past performance doesn't guarantee future results" is a normal disclosure, while a specific monthly percentage presented as an expectation is not.
Finally, test the support line before you deposit, not after. Ask a concrete question about withdrawal timing and see how quickly and precisely it's answered — that reply is a fair sample of what you'll get when it counts.
Reading a statement line by line
A statement is a record of movements, not a verdict. Deposits, withdrawals, positions opened and closed, and any fees each get their own line, and the balance at the bottom is simply the sum of everything above it.
The lines worth checking first
The opening and closing balance for the period, and anything you can't immediately explain. One unexplained line deserves an email; a pattern of them deserves a phone call.
Fees in plain sight
Anything deducted should show as its own labelled line. A fee that only appears as a smaller balance is a reason to ask questions.
Keeping your own record
Download each statement as it's issued rather than assuming the account will stay open forever. A folder with twelve files answers most questions faster than any support queue, and it's the record you'll want if you ever need one.
Investing involves risk, including the possible loss of some or all of the capital you invest. The value of investments can go down as well as up, and you may get back less than you originally put in. Do not invest money you cannot afford to lose.
