The number one reason traders blow their accounts is not picking the wrong coins — it's trading too large. Position sizing is the discipline of deciding exactly how much to put on each trade based on your stop loss distance.
Formula: Position Size = (Account × Risk%) ÷ (Entry − Stop Loss). Example: $10,000 account, 2% risk = $200 max loss. If your stop is $500 away from entry, you buy $200 ÷ $500 = 0.4 coins. This caps your loss at exactly $200.
Even with a 40% win rate, proper position sizing with 2:1 risk-reward keeps you profitable. Most failed traders simply skipped this step. Use this calculator on every trade before you enter.
Position sizing is deciding how large a trade to take. The goal is to risk a fixed % of your account on each trade so that no single loss is catastrophic.
Most professional traders risk 1–2% of their account per trade. Risking more than 5% per trade is considered high-risk and can blow accounts quickly during losing streaks.
Position Size = (Account Size × Risk %) ÷ (Entry Price − Stop Loss Price). This gives you the number of coins to buy so your loss is capped at your defined risk amount.
Without a stop loss you have no defined risk. Your position size becomes arbitrary. Always set a stop loss first, then calculate your position size around it.
Yes. With leverage your position size in the market increases but your margin requirement decreases. The risk calculator still shows your dollar risk — leverage amplifies both profits and losses from that base.
