Want a practical edge that isn’t another mindset tip? Size your trades by volatility. The idea is simple: when a symbol is calm, you can take more shares; when it’s wild, you take fewer. That keeps your dollar risk steady across different markets and days—stocks or crypto.
If you always buy the same number of shares, a quiet ticker barely moves your P&L while a jumpy one can wreck it. Volatility sizing evens that out so each trade risks about the same cash, no matter the chart.
Use Average True Range (ATR). In plain English, ATR tells you the typical daily move. If ATR is 1.20 on a $40 stock, it tends to swing about $1.20 per day. On a crypto pair priced at $2, an ATR of $0.08 means eight cents of usual movement.
Decide a fixed risk per trade—for example, $100. Choose a stop that makes sense on the chart (recent swing, invalidation level). Estimate the distance from entry to stop using ATR—many traders use 0.5× to 1× ATR as a guide. Position size = dollar risk ÷ stop distance.
Example (stock): Risk $100. ATR = $1.20. Your stop sits $0.60 from entry (≈0.5× ATR). Size = 100 ÷ 0.60 ≈ 166 shares.
Example (crypto): Risk $50. ATR = $0.008. Stop distance = $0.012. Size = 50 ÷ 0.012 ≈ 4,166 units.
ATR expands in fast markets and shrinks when things calm down. Recalculate before each trade or at least each session. When ATR doubles, your share count should roughly halve if you keep the same stop logic and dollar risk.
Stops belong where your idea is wrong—behind a clear level—not at a random ATR multiple. Use ATR only to estimate how far typical noise travels so normal wiggles don’t tag you out immediately.
Forcing the ratio: Don’t pick size first and squeeze the stop to fit. Set the stop logically, then size. Ignoring tick/min size: Check exchange rules so your size rounds to allowed increments. Forgetting fees or spreads: On smaller caps and illiquid coins, budget a little extra distance.
Before the open (or your crypto session), note ATR, your standard dollar risk, and expected stop distance for tickers on your watchlist. Jot the pre-calculated sizes. When the alert triggers, you already know the share or coin count—no guessing mid-move.
Volatility-based sizing is boring—in the best way. Pick a fixed cash risk, place a sensible stop, use ATR to translate that into size, and adjust as markets speed up or slow down. Your trades become consistent, and your equity curve gets smoother.
