MonsteadpeakStart with the pages nobody advertises: terms of use, risk disclosure and the withdrawal policy. A platform confident under scrutiny publishes these in full rather than reducing them to three friendly bullet points.
Then look at how potential returns are described. Language matters: 'past performance does not guarantee future results' is a normal disclosure, while a specific monthly percentage presented as an expectation is not.
Finally, test support before you deposit, not after. Ask a direct question about withdrawal timing and see how precisely it is answered - that reply is a fair sample of what you get when it actually matters.
Reading a statement line by line
A statement is a record of movements, not a verdict. Deposits, withdrawals, positions opened and closed, and any charges each appear on 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 any line you cannot immediately explain. One unexplained line is worth an email; a pattern of them is worth a phone call.
Fees kept visible
Any deduction should appear as its own labelled line. A charge that only shows up as a smaller balance is a reason to ask questions.
Keeping your own record
Download each statement as it is issued rather than assuming the account stays open forever. A folder of twelve files answers most questions faster than any support queue, and it is the record you will 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 fall as well as rise, and you may get back less than you originally put in. You should not invest money you cannot afford to lose.
