Most retail traders blow up not because their idea was wrong but because they sized it wrong. إدارة المخاطر is the architecture that lets a flawed idea survive طويلة enough for the good ideas to compound.
Rule 1: define risk before opportunity
Decide your risk per تداول as a percentage of equity (commonly 0.5%–1%) before أنت فتح the chart. Calculate the dollar value of that risk. Do not start hunting for setups until أنت know the size أنت are allowed to risk.
Rule 2: stop-loss is a constraint, not a suggestion
Place a stop-loss before entry, at a المستوى where the original idea is invalidated. Move it only in your favour or on time-based exits. Never widen a stop because price went against أنت. That is rule-breaking.
Rule 3: position size to fit the stop, not the أخرى way around
Given your risk dollars and your stop distance in pips, calculate position size. استخدم position size calculator; do not eyeball it. Eyeballing is how 0.5% trades become 5% losses.
Rule 4: hard يومي loss cap
Set a maximum يومي loss (e.g. 3R = three risk-units). متى أنت hit it, أنت are done for the day. Walking away after a bad سلسلة is the highest-impact discipline rule for retail traders.
Rule 5: max number of concurrent positions
Correlated positions amplify exposure. Three طويلة-EUR trades is one trade in three costumes. Cap concurrent positions, and treat correlated trades as a single risk.
Rule 6: track expectancy
Expectancy = (win % × متوسط win) − (loss % × متوسط loss). It is the average outcome per تداول. If expectancy is positive across enough trades, scale carefully. If it's negative, your priority is plugging the leak — not adding leverage.
Worked example
الحساب: $5,000. المخاطر per تداول: 1% = $50. Stop: 25 pips on EUR/USD. Pip value at 1 standard lot ≈ $10. المخاطر-dollar / (pips × pip-value) = 50 / (25 × 10) = 0.20 لوتات. استخدام 0.2 لوتات, not 1.0. The متداول who uses 1.0 because "the spread is so tight" is not trading; they are gambling 5% of equity in one click.
