Position sizing & risk management guide
Whether you call it a position sizing calculator, risk per trade calculator, or swing trading risk calculator, the goal is the same: survive long enough for your edge to work. Below is a concise reference aligned with how Swing Edge plans trades.
What is position sizing?
Position sizing is how many shares you buy relative to your account and your stop loss. It is not about conviction — it is about math. You decide the maximum loss you can accept (often expressed as 1R), divide that by your risk per share (entry minus stop), and that yields share count. A good NSE position size calculator also caps how much capital sits in one stock so a single mistake cannot dominate your portfolio.
Why traders fail at risk management
Most blow-ups are not bad entries — they are oversized positions. Traders size from hope (“this one will run”), ignore allocation limits, assume stops always fill, and confuse a high win rate with safe sizing. Without a fixed process, one gap-down or one oversized name can erase months of gains. Planning risk before the order is what separates professionals from gamblers.
What is 1R?
1R is your planned loss on a trade if the stop is hit — one unit of risk. If you risk ₹5,000 on a setup, that is 1R. A +2R target means you aim for ₹10,000 profit before considering partial exits. Thinking in R-multiples keeps decisions consistent across stocks and volatility regimes — the core of an R multiple calculator mindset.
How much should you risk per trade?
Many swing traders use 0.25%–1% of deployed capital per trade, with 0.5% a common default on a ₹10L swing book (₹5,000 at risk). Lower risk (0.25%) suits uncertain or bearish environments; higher risk only when setup quality, liquidity and market tone align. The calculator above lets you stress-test risk %, allocation caps and gap scenarios before you commit.
Why gap risk matters on NSE / BSE
Your stop is a intent, not a guarantee. Overnight news, earnings or broad sell-offs can open the stock below your stop — especially in smallcaps and illiquid names. Gap-risk simulation models a worse fill than your limit price so you see potential loss in rupees and in multiples of 1R. That is why survival-focused traders plan size and gap stress, not just the ideal stop fill.
Fixed fractional risk explained
Fixed fractional sizing means you risk the same fraction of capital on each trade (e.g. 0.5%), so position size in shares automatically shrinks when the stop is wider and grows when the stop is tighter — within your allocation cap. It keeps loss magnitude stable while allowing different technical structures. Pair it with a max % per stock and you have a complete swing risk framework.
