FX assumptions: 1.00 lot = 100,000 notional. For XXXUSD, $/pip = 10. USDJPY: $/pip = 1000 / price. USDCHF/USDCAD: $/pip = 10 / price. Crosses: $/pip = 10 x QUOTEUSD (or 1000 x JPYUSD for JPY quotes). Futures presets: ES $12.50/tick, NQ $5/tick, GC $10/tick, SI $25/tick, YM $5/tick, MBT $0.50/tick.

Formula: size = (account*risk% - buffer) / (stop_in_pips_or_ticks x $/pip_or_tick). Then floor to step, clamp to [min,max].


What does this calculator do?

It helps you decide how many lots/contracts to trade so that if your stop is hit, you only lose the small percent of your account you chose (many traders use 1% or less). You pick your market, type in your account size, risk%, and stop distance. We do the rest.

Quick example (Forex)

You trade EURUSD, have a $10,000 account, risk 1%, and your stop is 30 pips. The calculator suggests a lot size that keeps the loss near $100 if price tags your stop. That’s it—simple and disciplined.

Quick example (Futures)

You trade ES, account $25,000, risk 1%, and your stop is 12 ticks. We work out how many contracts fit that risk. No guesswork, no “I think it’s about right.”

Pips vs. Ticks (one-liner)

  • Pips = Forex steps (EURUSD, GBPUSD, USDJPY, etc.).
  • Ticks = Futures/CFDs steps (ES, NQ, GC, SI, YM, etc.).

Pick your symbol first—if it’s FX we use pips, if it’s futures/CFDs we use ticks.

Why position sizing matters

  • It keeps every trade small enough that one loser never ruins your week.
  • It makes your process repeatable—same rules, every time.
  • It frees your mind to focus on the setup instead of the math.

Simple tips

  • Pick a small risk (0.5%–1.0%) and stick to it.
  • Choose your stop from the chart first (structure/volatility), then size the position.
  • Use the “Fees/Slippage Buffer” if commissions or spreads add up on your broker.
  • Round down to the lot step to stay under your planned risk.

Educational use only. Trading involves risk. Always confirm symbol specs with your broker/exchange.
