Position Sizing for Volatile Markets: The 1R Framework

What 1R actually means

1R is the dollar amount you're willing to lose if your stop is hit. It's the unit of measurement for every trade you take — not the position size, not the leverage, not the notional.

The volatility-adjusted formula

Position size = (Account × Risk %) / (Entry − Stop)
That denominator is where volatility lives. As ATR expands, your stop widens, and your size *must* shrink to keep 1R constant. Traders who hold size constant through volatility regime changes are the ones who blow up in week three of a trending market.

Practical rules

• Risk 0.5% – 1% per trade if you take 10+ setups per week.
• Risk 1% – 2% per trade if you take 1–3 setups per week.
• Never stack correlated trades past 2R of total exposure (BTC + ETH + SOL longs = one trade, not three).
• Cut size in half after two consecutive losses. Restore after one full win.

Why this matters more than your edge

A 60% win-rate strategy sized incorrectly will still blow an account. A 45% win-rate strategy sized correctly with 2R winners is profitable in perpetuity. Sizing is the multiplier on every edge you have.

How the Trade Feeld Risk Engine helps

Every alert ships with a volatility-adjusted stop and a recommended size based on the account value you configure. You can override it, but you can't ignore it — the engine refuses to submit orders that breach your daily drawdown cap.
