Stop out

MetaTrader 5 processes stop-out closes on the server. Where FIFO closing is off, it closes the position with the largest loss first. The trigger level is part of the account's trading conditions, not a single number in the help page. UK retail accounts have a separate legal rule. COBS 22.5 requires the firm to close the relevant open positions as soon as market conditions allow, once net equity is below 50% of the margin needed to maintain them. A firm may implement that duty with its stop-out setting. The handbook text is the legal test. The platform help is the software's closing order.
