Position Sizing Basics – Bittime

How to Control Risk Per Trade

1. What Is Position Sizing?

Position sizing means deciding how large a position to open based on your account balance, the distance to your stop-loss, and the amount of capital you are willing to risk on that single trade.

It is not the same as choosing leverage. Leverage determines how much margin is required; position sizing determines how much of your account is effectively at risk.

2. Why Position Sizing Matters

A trader who risks 10% of their account on every trade only needs a short series of losses to suffer severe damage. A trader who consistently risks 1–2% per trade can withstand many consecutive losses and still remain in the game long enough to improve.

On Bittime USDT-margined perpetual futures, the combination of leverage (up to 25x) and position size determines both your potential profit and your liquidation distance.

3. A Simple Risk-Based Approach

One practical method used by many traders is:

Risk Amount = Account Balance × Risk Percentage

Then calculate position size so that if the stop-loss is hit, the loss approximately equals the Risk Amount.

Example:

Account balance: 1,000 USDT

Risk per trade: 2% → Risk Amount = 20 USDT

You plan to buy (long) with a stop-loss 2% below entry price.

Approximate position value you can take ≈ 20 USDT ÷ 2% = 1,000 USDT

If you use 5x leverage, the margin required would be roughly 200 USDT.

This is a simplified illustration. Always verify the actual liquidation price and fees on the platform.

4. Practical Guidelines for Beginners

Start by risking a very small percentage (0.5%–1%) while learning.
Never risk more than you can emotionally accept losing on a single trade.
Prefer Isolated Margin so that risk is limited to the margin allocated to that position.
Reduce size when market volatility is high.
Increase size only after you have demonstrated consistent risk control over many trades.

5. Position Sizing vs Leverage

Concept	What It Controls	Beginner Recommendation
Leverage	Margin required & liquidation distance	Start 2x–5x, max platform 25x
Position Size	How much capital is at risk	Risk only small % of total balance
Stop-Loss Distance	Where you exit if wrong	Always define before entry

All three must work together. High leverage + large position size + no stop-loss is the most common path to rapid account loss.

6. Key Takeaways

Position sizing is the primary tool for controlling risk. Focus first on surviving and staying consistent. Profitability comes later. On Bittime, always confirm the liquidation price after setting your desired size and leverage.
