Position sizing refers to how much capital a trader allocates to a single trade based on their account size and risk tolerance. It ensures that each trade carries a controlled level of risk, usually expressed as a percentage of the account. Proper position sizing is a key part of risk management and helps traders stay consistent.

Profit Target

A profit target is a predefined level at which a trader plans to close a trade or complete a trading objective once a certain amount of profit is reached. It helps traders lock in gains and avoid holding positions for too long. In structured environments like prop trading, a profit target can also refer to the required return a trader must achieve during an evaluation.

Traders are given a simulated account with defined profit targets and risk parameters — such as maximum daily drawdown and overall drawdown limits — that must be met over a set period. Completing the challenge typically results in the trader receiving capital to trade with, keeping a percentage of the profits generated.
