Most retail traders know at least one approach that has positive expectancy in theory. The difference is almost always in how money is managed. Here are the rules that separate the two groups. --- ## Rule 1 - Professionals Know Their Exact Risk Per Trade Before Entering An amateur enters a trade at a lot size that "feels right" or matches their usual size. They set a stop "somewhere below support" without calculating the dollar risk. A professional calculates: account balance x risk percentage / (stop pips x pip value) = lot size. They do this before every entry without exception. The result: professionals know the maximum they can lose on any trade before entering. Amateurs find out after the trade closes. --- ## Rule 2 - Professionals Do Not Move Stops Against the Plan Every retail trader who has blown an account has moved a stop loss in the losing direction at least once during that account's life. The trades where stops are moved tend to be the largest single losses in any account history. Professional traders treat the stop loss as a commitment, not a suggestion. When price reaches the stop, the trade is over and the loss is accepted. There is no negotiation. --- ## Rule 3 - Professionals Have Daily and Weekly Loss Limits Amateur traders do not stop when they are having a bad day. They keep trading, often with larger sizes, trying to recover what they have lost. This revenge trading is responsible for the catastrophic single-day losses that appear in almost every retail account history. Professional traders have hard limits. Hit the daily limit, close the platform. Hit the weekly limit, stop until Monday. These rules are enforced unconditionally. --- ## Rule 4 - Professionals Size Positions as a Percentage of Capital, Not a Fixed Lot Amateurs trade 0.1 lots every trade, regardless of account size or stop distance. Their actual risk per trade varies from 0.1% to 5% depending entirely on where they happen to place the stop. Professionals recalculate lot size for every trade to maintain consistent risk as a percentage of the current account balance. --- ## Rule 5 - Professionals Do Not Increase Position Size During Drawdowns When an account is in a drawdown, the instinct is to increase position size to recover faster. This instinct is almost always wrong. Larger positions during a losing period amplify losses, deepen the drawdown, and make recovery harder. Professionals do the opposite: reduce size during drawdowns. The reduced position sizes mean the drawdown slows. When the strategy recovers, positions gradually return to normal size. --- ## Rule 6 - Professionals Track Their Actual Performance Amateurs have a vague sense of how they are doing. They remember their winning trades more clearly than their losing ones. Their self-assessment is optimistic. Professionals maintain a journal with precise data. They know their win rate to the decimal point, their profit factor for each setup type, their maximum drawdown for each quarter, and their average risk per trade versus their planned risk per trade. This data-driven self-awareness is not optional for professional traders - it is how they identify problems before they become catastrophic. --- ## Rule 7 - Professionals Treat Trading as a Business Amateurs focus on individual trades. "Did this trade work? Did this one?" Professionals focus on statistical outcomes across large samples. They understand that any individual trade result is nearly irrelevant. What matters is whether the system produces positive expectancy across hundreds of trades. This framing change - from individual trade outcomes to statistical performance - is what allows professionals to take losses without emotional disruption. A losing trade is just one data point in a large, ongoing experiment. --- All of these rules are measurable in a trading journal. Your journal shows you whether you are consistently calculating position sizes, how often stops were moved, and what your actual risk-adjusted performance looks like.
