Crypto Position Size Calculator (ATR-Based)
What is ATR-Based Position Sizing?
ATR (Average True Range) position sizing uses market volatility to determine position size. Instead of fixed dollar amounts, you risk a percentage of your account based on how volatile the asset is right now. This is how dMoERA's trading bots size every trade.
How It Works
- Enter your account size in USD
- Enter your risk per trade as a percentage (1-2% is standard)
- Enter the ATR value for your asset (14-period ATR is common)
- Enter the current price of the asset
- The calculator shows your position size in USD and in units
Why ATR Instead of Fixed Stop Loss?
Fixed stop losses (e.g., "stop at $40,000") don't account for volatility. When BTC is volatile, a tight stop gets hit by noise. When it's calm, a wide stop wastes risk budget. ATR-based stops adapt: wider when volatile, tighter when calm. This is the approach used by every bot in dMoERA's 80-bot roster.
The Formula
Position Size (USD) = (Account Size × Risk %) / (ATR × ATR Multiplier)
The ATR multiplier (typically 1.5-3.0) determines how many ATRs your stop is from entry. A multiplier of 2.0 means your stop is 2 ATRs away.
Frequently Asked Questions
- What ATR multiplier should I use for crypto?
- For crypto, 1.5-2.0 ATR is common for shorter-term strategies, while 2.5-3.0 ATR works for swing trading. dMoERA's bots use strategy-specific multipliers validated through walk-forward testing.
- How much should I risk per trade in crypto?
- Professional crypto traders typically risk 0.5-2% of their account per trade. Risking more than 2% per trade can lead to significant drawdowns during losing streaks.
- What is ATR in crypto trading?
- Average True Range (ATR) measures the average price range of an asset over a given period (usually 14 bars). It accounts for gaps and limits, making it a more realistic volatility measure than simple price range.
- How does dMoERA use ATR sizing?
- Every bot in dMoERA's roster uses ATR-based stops and position sizing. The ATR multiplier is part of each strategy's metadata and is validated through the 7-stage validation pipeline before the bot goes live.
