Trading Fundamentals
Practical principles for managing trading risk, including position sizing, stop-loss orders, leverage awareness, and discipline.
Risk management is an important part of trading. Markets are uncertain, and even well-researched trades can move against you. The goal of risk management is not to eliminate losses, but to define potential loss in advance and reduce the impact that any single trade, or short series of trades, may have on your account.
Position sizing determines how much of your capital is exposed to a single trade. Some traders use a fixed percentage of account equity to help define risk per position, such as 1–2%, though the appropriate amount depends on account size, market conditions, and individual risk tolerance. Smaller position sizes can help reduce the impact of individual losing trades.
A stop-loss order is designed to close a position once the market reaches a predefined price level. It can help define an exit level in advance, but it does not guarantee a maximum loss. Execution is not guaranteed at the exact stop price during fast-moving or low-liquidity market conditions, and slippage may occur.
A take-profit order is designed to close a position once a target level is reached. When used with a stop-loss order, it can help define planned exit levels before entering a trade. Some traders compare the potential loss and potential gain of a setup using a risk-to-reward ratio, but this does not guarantee the outcome of any trade or strategy.
Leverage allows traders to control a position larger than the capital required to open it, but it can also amplify both gains and losses. Higher leverage increases market exposure and may lead to rapid losses if the market moves against the position. Traders should understand margin requirements and the effect of leverage before opening leveraged trades.
Holding several positions in highly correlated instruments can increase exposure to similar market movements. Understanding correlation - for example, between major currency pairs or commodity-linked currencies - can help traders assess whether multiple positions are adding similar risks to the account.
Emotional decision-making can affect how traders enter, exit, and manage positions. Using predefined entry, exit, and risk rules, along with a trading journal, can help traders review decisions and identify patterns in their behavior over time.
