How it works

We calculate the lot size so that if price moves 20 pips against you, you will lose exactly $100.00 (1% of balance).

How to use the MT4 Position Size Calculator

  1. Currency & Balance: Select your account currency (USD supported) and enter your current balance.
  2. Risk Percentage: Choose how much of your account you are willing to risk on this trade (e.g., 1%).
  3. Select Pair: Choose the currency pair you are trading (e.g., EUR/USD).
  4. Stop Loss (Pips): Enter the distance in pips from your entry price to your stop loss.

Why Position Sizing Matters in Forex

In Forex trading, managing lot sizes is the single most important factor for long-term survival. The Pineify MT4 Position Size Calculator helps you adhere to the "1% Rule" or "2% Rule" seamlessly.

By calculating the exact lot size for every trade based on your stop loss distance, you ensure that a losing trade never impacts your account more than you planned. Whether your stop loss is 10 pips or 100 pips, your dollar risk remains constant.

A Mini Lot is 10,000 units (0.10 Standard Lots). It is worth approximately $1 per pip on major pairs.

Do I need to enter the Current Price?

Only for pairs where the US Dollar is not the quote currency (like USD/JPY or USD/CAD), as the pip value changes with the exchange rate.
