What Is Risk Management

One trade, three numbers

Risk management is one habit: the money a trade may lose is set before the trade, and the trade's size is whatever makes that number true. Take the euro against the dollar at its 17 December 2025 close, 1.17398, on a 10,000-dollar example account. The money is set first: one per cent, 100 dollars. The distance to the stop is read off the chart — 25 pips here, as an example. One pip at one lot on the euro is 10 dollars. So the size is 100 divided by 25 times 10, which is 0.40 lot, and if the stop is hit the trade loses exactly the 100 dollars chosen. The size was never picked; it was the answer.

A ship built in compartments

Picture a ship built in watertight compartments. One compartment floods, and the ship floats, because the bulkheads keep the water where it is. Risk management is the bulkheads. Each compartment is one trade, the bulkhead is the stop, and the height of the wall is the most that trade may lose — one per cent of the account in the first drawing. A ship with no bulkheads sinks from one hole. An account with no limit per trade sinks from one trade, and it does not matter how good the other trades were, because the water does not know.
