Position sizing is the process of deciding how big (or small) each trade should be. It is not about \u201chow much money I want to make\u201d \u2014 it is about \u201chow much money I am willing to lose if I am wrong.\u201d
Proper position sizing is the difference between surviving long enough to become profitable and blowing up your account in a few bad trades. This article is not financial advice or trading advice. Only an opinion on each issue.<\/p>\n\n\n\n

The Core Idea<\/h3>\n\n\n\n

You first decide how much of your total capital you are willing to risk on one trade (usually 0.5 % \u2013 2 %).
Then you adjust the number of shares, lots, or contracts so that if your stop-loss is hit, you lose exactly that pre-decided amount \u2014 no more, no less.<\/p>\n\n\n\n

Position Sizing Formula (Universal for Stocks and Forex)<\/h3>\n\n\n\n

Position Sizing in Stock<\/a>, Forex Trading<\/a>, and Commodity Trading<\/a> are working in the same way. General calculation is, Position size = (Account balance \u00d7 Risk % ) \u00f7 (Distance from entry to stop-loss in $ or pips \u00d7 Value of 1 unit)<\/p>\n\n\n\n

Real-Life Examples<\/h3>\n\n\n\n

Example 1 \u2013 Forex (EUR\/USD)<\/h4>\n\n\n\n

Account balance: $8,000
Risk per trade: 1 % = $80 maximum loss
Planned stop-loss: 35 pips<\/a> away<\/p>\n\n\n\n

$80 \u00f7 35 pips = $2.29 per pip
In EUR\/USD, $10 per pip = 1 standard lot
So you can trade approximately 0.23 standard lots (or 2.3 mini lots \/ 23 micro lots)<\/p>\n\n\n\n

Result: If price hits your stop, you lose exactly $80 (1 %).
Your account becomes $7,920 and you live to trade another day.<\/p>\n\n\n\n

Example 2 \u2013 Stock Trading (NVDA)<\/h4>\n\n\n\n

Account balance: $50,000
Risk per trade: 1 % = $500 maximum loss
NVDA current price: $135
You plan to buy and place stop at $128
Distance to stop: $7 per share<\/p>\n\n\n\n

Maximum shares = $500 \u00f7 $7 = 71.4 \u2192 71 shares
Position value = 71 \u00d7 $135 \u2248 $9,585<\/p>\n\n\n\n

Result: If NVDA drops to $128, you lose $497 (very close to 1 %).
Your account is now $49,503 \u2014 barely noticeable.<\/p>\n\n\n\n

Example 3 \u2013 Small Forex Account<\/h4>\n\n\n\n

Account balance: $1,200
Risk per trade: 2 % = $24 maximum loss
Pair: GBP\/JPY
Stop-loss: 80 pips<\/p>\n\n\n\n

$24 \u00f7 80 pips = $0.30 per pip
You trade 0.03 standard lot (3 micro lots)<\/p>\n\n\n\n

Result: Even with a tiny account, you can still follow the same rule perfectly.<\/p>\n\n\n\n

Example 4 \u2013 Futures (ES \u2013 E-mini S&P 500)<\/h4>\n\n\n\n

Account balance: $35,000
Risk per trade: 0.75 % = $262.50
Current ES price: 5,800
Stop planned at 5,770 (30 points away)
1 point = $50 per contract<\/p>\n\n\n\n

$262.50 \u00f7 (30 points \u00d7 $50) = 0.175 \u2192 1 contract (rounded down for safety)
Actual risk with 1 contract = 30 \u00d7 $50 = $1,500 \u2192 too much
So you trade 0 contracts or wait for a setup with a tighter stop.<\/p>\n\n\n\n

Common Position Sizing Methods in 2025<\/h3>\n\n\n\n
    \n
  1. Fixed Percentage Risk (most popular)
    Always risk the same % of current balance (e.g., 1 %).<\/li>\n\n\n\n
  2. Fixed Dollar Risk
    Risk the same dollar amount every trade (e.g., always $200).
    Works well when accounts are small.<\/li>\n\n\n\n
  3. Volatility-Based (ATR method)
    Stop distance = 1.5 \u00d7 ATR(14)
    Bigger stops on     volatile pairs<\/a> \u2192 automatically smaller position size.<\/li>\n\n\n\n
  4. Equity Curve Adjustment
    Risk 2 % when account is above moving average, 0.5 % when below.<\/li>\n<\/ol>\n\n\n\n

    Why Most Traders Get Position Sizing Wrong<\/h3>\n\n\n\n
      \n
    • They decide position size based on how much profit they want (\u201cI\u2019ll buy 500 shares so I can make $1,000\u201d).<\/li>\n\n\n\n
    • They use the same fixed lot size regardless of stop distance.<\/li>\n\n\n\n
    • They ignore account size changes (still trading 1 lot after the account has dropped 50 %).<\/li>\n\n\n\n
    • They mentally round up \u201cjust this once\u201d because the setup looks perfect.<\/li>\n<\/ul>\n\n\n\n

      The Math That Keeps Traders Alive<\/h3>\n\n\n\n

      If you lose 50 % of your account, you need a 100 % gain just to break even.
      If you never risk more than 1\u20132 %, even 20 losing trades in a row leave you with 80\u201365 % of your capital \u2014 completely recoverable.<\/p>\n\n\n\n

      Position sizing is boring, mathematical, and unemotional \u2014 which is exactly why it works.
      It is the one part of trading that is 100 % under your control on every single trade, regardless of market conditions. As one master it, the market can never take one out of the game.<\/p>\n","protected":false},"excerpt":{"rendered":"
