Lot Size Calculator
Size every trade for the risk you accept.

Pick an instrument, enter your balance and stop-loss, and the calculator returns the exact position size that keeps your risk under control. Same execution rules every account on MondFx already uses.

Why use it

Risk discipline,
before every order.

The most expensive mistake in trading is sizing the next position by feel. This tool does the math so the discipline does itself.

R01

Quantified risk

Define the loss you are willing to take in absolute or percentage terms — the calculator tells you the size that respects it.

R02

Consistent sizing

Every trade is sized against your real balance, not a number you remember from last week. Sized for the account you have right now.

R03

Same rails, every account

Identical pip and contract data to what you see in MetaTrader 5 — no surprises between the planner and the platform.
