R-Multiple Calculator
Enter your entry price, stop loss, and exit price to express the trade outcome in R — the universal unit for comparing risk-adjusted results across any market, timeframe, or position size.
What R-multiples are
R stands for risk. Before you enter a trade, the distance from your entry to your stop loss defines one R: the maximum loss you have accepted for this particular trade. When the trade closes, the profit or loss expressed as a multiple of that initial risk is the R-multiple. A trade that made twice the initial risk is +2R. A trade that was stopped out for a quarter of the risk is −0.25R.
The value of R-multiples is that they strip away the dollar amounts and the position sizes, leaving you with a number that describes the quality of a trade independent of how much money was at stake. A +3R on a ten-dollar trade and a +3R on a ten-thousand-dollar trade represent the same quality of outcome. This makes it possible to compare trades across completely different instruments, account sizes, and timeframes on an equal footing.
Why R-multiples are used
The most direct use of R is calculating expectancy. Expectancy is the average R-multiple across all of your trades. If your trades average +0.4R, you make forty cents for every dollar you risk over a large sample. A positive average R means you have an edge; a negative one means you do not, regardless of how high your win rate is. This is what makes R-multiples more informative than win rate alone.
R-multiples also make the relationship between win rate and required reward concrete. To break even with a 1:1 reward-to-risk ratio, you need a 50% win rate. At 2R average win, you only need to be right 34% of the time. Framing trades in R makes these trade-offs visible before you put on a position.
These are descriptive figures calculated from past trades. How you interpret them and whether you trade based on them is entirely your own decision.
What are TradingView and Pine Script?
TradingView is one of the most widely used charting and market-analysis platforms, where traders and analysts study price movement across stocks, crypto, forex, and futures on interactive charts. Pine Script is TradingView's own lightweight programming language, created so anyone can build custom tools that run directly on those charts.
People use Pine Script to build four main kinds of tools. Indicators calculate and plot values on the chart, exactly like the calculation above, but recomputed automatically on every bar. Strategies add explicit entry and exit rules and can be backtested against historical data in TradingView's Strategy Tester to see how they would have behaved. Screeners scan many symbols at once for conditions you define. Alerts notify you the moment a condition you specified occurs, so you do not have to watch the screen.
The value is precision and automation. Instead of eyeballing a chart, you describe exactly what you want measured, visualized, or notified about, and TradingView runs it consistently across any market and timeframe. That is why traders, analysts, and developers write Pine Script: it turns a manual charting idea into a repeatable tool. These tools are for tracking, visualizing, and testing market ideas; they do not tell you what to trade, and that decision always remains yours.
Writing that code by hand means learning Pine Script's syntax, its type system, and the exact names of hundreds of built-in functions. It is a real programming language, and small mistakes stop a script from compiling in the Pine Editor.
Turn this into Pine Script
You calculated this R-multiple from individual prices. When a strategy is running in TradingView, Pine Script gives you access to closed-trade details through the strategy.closedtrades.* built-ins, so you can compute R-multiples automatically for every trade the strategy has taken and display them as labels or a table on the chart. The work is getting your entry, stop, and exit logic into that strategy in the first place.
//@version=6
strategy("R-Multiple Tracker", overlay=true)
// ... your entry and exit conditions here ...
// After each trade closes, the R-multiple is: profit divided by initial risk.
// Replace stopDistance with the actual stop you used on entry.
stopDistance = ta.atr(14) * 1.5
if strategy.closedtrades > 0
lastPnl = strategy.closedtrades.profit(strategy.closedtrades - 1)
lastEntry = strategy.closedtrades.entry_price(strategy.closedtrades - 1)
lastR = stopDistance[strategy.closedtrades.entry_bar_index(strategy.closedtrades - 1)]
rValue = lastEntry != 0 and lastR != 0 ? lastPnl / lastR : na
label.new(bar_index, high, "R: " + str.tostring(rValue, "#.##"), style=label.style_label_down)PineScripter is an AI built specifically for Pine Script. You describe what you want in plain English and it writes TradingView-ready v6 code. Because it is specialized on the Pine Script language and its exact function signatures, it tends to produce code that compiles far more reliably than general-purpose models like ChatGPT, which often invent functions that do not exist in Pine Script.
