Decide your risk first, and let the maths set your lot size. This is the single most important habit a trader can build.
Professional traders do not ask "how much can I make?" They ask "how much can I lose if I'm wrong?" — and they fix that number before entering. This tool does the rest: given your balance, your risk percentage, and your stop-loss distance, it tells you the largest position you may take.
Lots = (balance × risk%) ÷ (stop-loss pips × pip value per lot). Keep risk at 1–2% and a string of losses can never wipe you out. Ignore this and one bad trade can.
Risk warning. Trading forex and CFDs carries a high level of risk and may not be suitable for everyone. You can lose more than your initial deposit.
