📖 Risk Management Guide

POSITION SIZING

The golden rule: never risk more than 1–2% of your account on a single trade. This ensures you can survive a losing streak without being wiped out.

RISK:REWARD RATIO

Always aim for at minimum a 1:2 R:R ratio — risk $1 to make $2. A 1:3 ratio is even better. With a 50% win rate and 1:2 R:R, you still profit.

STOP LOSS RULES

Always set a stop loss before entering a trade. Place it below key support (for longs) or above resistance (for shorts). Never move SL against your position.

⚠️ Common Mistakes

MISTAKE No stop loss — "it will come back"

MISTAKE Risking 10–20% on one trade

MISTAKE Moving SL further into loss

MISTAKE Averaging down without a plan

MISTAKE Trading without a defined risk plan

CORRECT 1–2% risk, 1:2+ R:R, fixed SL

🧮 Key Formulas

Position Size ($) = (Balance × Risk%) / SL Distance% SL Distance% = |Entry - SL| / Entry × 100 R:R Ratio = |TP - Entry| / |Entry - SL| Kelly % = (W × b - L) / b where b = Avg Win / Avg Loss Expectancy = (Win% × Avg Win) - (Loss% × Avg Loss) Liq Price (Long) = Entry × (1 - 1/Leverage) Liq Price (Short) = Entry × (1 + 1/Leverage)

🏆 Professional Tips

✦ Max 2–3 open trades simultaneously

✦ Daily loss limit: max 5–6% of account

✦ After 3 consecutive losses — stop trading

✦ Scale in: enter 50%, add on confirmation

✦ Scale out: take 50% at TP1, ride to TP2

✦ Move SL to breakeven after TP1 is hit

✦ Keep a trading journal — track every trade
