Position Sizing Based on Account Equity
Introduction to Position Sizing and Simple Hedging
Welcome to trading. This guide focuses on how to manage the size of your trades, especially when you hold assets in the Spot market and decide to use Futures contracts for protection or speculation. For beginners, the most important takeaway is this: Start small, never risk more than you can afford to lose, and use futures primarily to protect what you already own before trying to amplify gains. Understanding Risk Sizing for a First Futures Trade is more critical than chasing large profits immediately.
Balancing Spot Holdings with Partial Futures Hedges
Many new traders confuse Spot Trading Versus Futures Trading. Spot trading involves buying and holding the actual asset. Futures trading involves contracts whose value is derived from the underlying asset, often using leverage.
When you own assets on the spot market, you face the risk of price drops. A simple, safe way to start using futures is through partial hedging. This means using a short futures position to offset only a portion of your spot risk, not all of it. This strategy aims to reduce volatility rather than eliminate profit potential entirely.
Steps for Partial Hedging:
1. Determine Total Spot Value: Know exactly how much crypto you currently hold. 2. Decide on Hedge Ratio: For a beginner, start with a 25% or 50% hedge. If you hold $1000 worth of Bitcoin, a 50% hedge means opening a short futures position worth $500. This protects you against a downside move while allowing you to benefit partially if the price rises. This is often covered in When to Use Full Versus Partial Hedges. 3. Set Leverage Cautiously: If you are hedging, you do not need high leverage. Excessive leverage magnifies liquidation risk, which is a major danger, as detailed in Understanding Liquidation Price Levels. For hedging, keep leverage low (e.g., 2x or 3x) to ensure your hedge position remains open without immediate threat of liquidation. Review Avoiding Overleverage in New Accounts.
Remember that funding rates and trading fees will impact your net results, regardless of price movement. Also, when you close the hedge, you must plan your exit carefully, as discussed in When to Close a Protective Hedge.

Using Indicators for Timing Entries and Exits
Technical indicators can help time when to open or close your spot positions or your protective hedges. However, indicators are not crystal balls; they should be used for confluence, not as absolute buy/sell signals. Never trade based on a single indicator reading.
Momentum and Volatility Indicators:
- RSI (Relative Strength Index): This shows if an asset is potentially overbought (often above 70) or oversold (often below 30). In a strong uptrend, the RSI can stay overbought for a long time, so context is vital. Use RSI readings to confirm a potential reversal point for closing a spot buy, or to time a Spot Buying Entry with Futures Protection.
- MACD (Moving Average Convergence Divergence): This compares two moving averages to show momentum changes. A bullish crossover (MACD line crossing above the signal line) suggests increasing buying pressure. Be aware of MACD Lag and Whipsaw Risks; crossovers can be delayed or give false signals in choppy markets. Interpreting MACD Crossovers Simply is a good starting point.
- Bollinger Bands: These bands show volatility. When bands tighten, volatility is low, often preceding a large move. When the price touches the upper band, it suggests relative strength, but not necessarily a guaranteed top. Use Bollinger Bands and Volatility Context to gauge the market environment.
Always validate signals using Validating Volume Data. High volume confirms significant market interest behind a price move or indicator signal.
Position Sizing Based on Account Equity
Position sizing is the process of determining how much capital to commit to a single trade. The core principle is risk management: size your position based on the percentage of your total trading equity you are willing to risk on that trade, not just the dollar amount you want to buy.
A common conservative rule is risking only 1% to 2% of your total account equity on any single trade.
Example Calculation:
Assume your total trading account equity is $5,000. You decide you will risk a maximum of 2% per trade.
Risk Amount = $5,000 * 0.02 = $100.
This $100 is the maximum loss you will accept before your stop-loss is hit.
Next, you need to determine where your stop-loss will be placed based on your entry criteria (e.g., technical analysis or indicator signals). If you enter a spot trade at $50,000, and your planned stop-loss is $48,000 (a $2,000 difference per coin), you can calculate the maximum number of units you can buy:
Position Size (Units) = Risk Amount / (Entry Price - Stop Loss Price) Position Size (Units) = $100 / ($50,000 - $48,000) = $100 / $2,000 = 0.05 units.
If you are using futures, this calculation determines the notional value of your futures position. For more detailed formulas, see How to calculate position size in crypto trading. This method ensures that a string of bad luck does not wipe out your account.
Risk/Reward Scenario Table (Spot Trade Sizing Example)
| Parameter | Value ($) |
|---|---|
| Total Equity | 5000 |
| Max Risk % | 2.0% |
| Max Dollar Risk | 100 |
| Entry Price | 50000 |
| Stop Loss Price | 48000 |
| Calculated Position Size (Units) | 0.05 |
When using futures, remember that leverage changes the dollar risk relative to the margin required, but the underlying equity risk (the $100 in this example) should remain fixed based on your stop-loss distance. If you use high leverage, the margin requirement is lower, but the distance to the Liquidation Price Levels becomes much tighter.
Even with perfect sizing, poor psychology can destroy an account. Beginners often fall prey to common emotional traps:
- Fear of Missing Out (FOMO): Buying simply because a price is rising rapidly, often ignoring established entry rules or indicator signals. This leads to buying at tops.
- Revenge Trading: Trying to immediately win back losses from a previous trade by taking an oversized or poorly planned subsequent trade. This is a direct violation of proper Entry Triggers Based on Price Action.
- Overleverage: Using excessive leverage in Futures contracts hoping for quick returns. This drastically increases the probability of forced closure of your position. Always review your settings, especially if your exchange defaults to a high Position Mode.
To counteract these, stick rigidly to your predetermined position size and stop-loss levels. If a trade hits your stop-loss, accept the small, planned loss and move on. Do not immediately seek compensation. Reviewing your trade journal helps identify patterns in your emotional decision-making.

Conclusion
Managing position size based on account equity is the foundation of sustainable trading. For beginners, this means prioritizing the protection of your Spot market assets first, perhaps using a Selling Spot Assets Using Short Hedges strategy, before aggressively seeking leveraged gains. Always calculate your risk before you calculate your potential reward, and remember that consistency in position sizing trumps occasional large wins.
