RiskGuard Position Size Calculator

Drag the stop line on your chart and see the lot size update live. Sizes every trade from your own risk setting, using the broker's real contract size and lot step. It does not trade and it sends no orders.

What it does

Set the stop where you actually want it - by dragging a line on the chart, not by typing points into a box - and read the lot size straight off the panel.

The panel shows direction, entry, stop, stop distance in price and points, your risk in both percent and account currency, the lot size, margin needed, free margin afterwards, and reward-to-risk from the optional target line.

Direction is automatic. Put the stop below price and it reads BUY; above price and it reads SELL. One line covers both cases.

It tells you when the minimum lot is too big for your risk

This is the part most calculators get wrong. If your stop is tight, or your account is small, the broker's minimum lot can risk more than the amount you asked for. Most tools show the minimum lot and say nothing.

This one turns amber and shows both numbers - what you asked to risk, and what the minimum lot would actually cost you. What you do about it is your decision, but you will not make it without knowing.

Everything comes from your broker, nothing is hardcoded

Tick value, tick size, lot step, minimum and maximum volume are all read from the symbol you are on. That is why it gives correct answers on gold, indices and crypto CFDs, not only on standard FX pairs.
