RSI Calculator
Calculate Relative Strength Index from sequential closing prices.
Compute RSI deterministically by deriving average gains and losses from close-to-close price changes.
Results
RSI
80.00
RSI is 80.00 using average gain 1.6000 and average loss 0.4000.
- Average gain
- 1.6000
- Average loss
- 0.4000
- RS
- 4.0000
- RSI
- 80.00
Formula
RSI = 100 - (100 / (1 + RS)), where RS = Average Gain / Average Loss
Example
- Close 1: 100
- Close 2: 102
- Close 3: 101
- Close 4: 104
- Close 5: 103
- Close 6: 106
What does this mean?
- •RSI above 70 can indicate overbought conditions.
- •RSI below 30 can indicate oversold conditions.
- •RSI works best with trend and volume confirmation.

RSI helps frame overbought/oversold zones with deterministic math.
What is a rsi?
Compute RSI deterministically by deriving average gains and losses from close-to-close price changes. In practice, this means you can quantify rsi using close 1, close 2, close 3, close 4, close 5, and close 6 without relying on hidden assumptions or black-box scoring.
Primary input set for this calculator: Close 1, Close 2, Close 3, Close 4, Close 5, Close 6.
How to calculate rsi
- 1.Step 1: Enter close 1 with the timeframe/context you want to evaluate.
- 2.Step 2: Enter close 2 with the timeframe/context you want to evaluate.
- 3.Step 3: Enter close 3 with the timeframe/context you want to evaluate.
- 4.Step 4: Enter close 4 with the timeframe/context you want to evaluate.
- 5.Step 5: Enter close 5 with the timeframe/context you want to evaluate.
- 6.Step 6: Enter close 6 with the timeframe/context you want to evaluate.
- 7.Step 7: Apply formula RSI = 100 - (100 / (1 + RS)), where RS = Average Gain / Average Loss.
- 8.Step 8: Interpret output together with risk, liquidity, and catalyst context.
Why this metric matters
This metric helps convert raw time-series data into consistent signals for momentum, mean-reversion, and volatility context.
Pair this calculator with catalyst context from headlines, filings, and options flow to avoid relying on isolated numbers.
When to use this calculator
- ✓Before opening a new position where rsi impacts sizing or risk.
- ✓After a catalyst to quantify how much conditions changed versus your baseline.
- ✓When comparing setups across multiple tickers with one consistent formula.
- ✓During weekly review to keep decision-making tied to measurable inputs.
Common scenarios
RSI above 70 can indicate overbought conditions
Use this rsi workflow to quantify this scenario with deterministic inputs.
RSI below 30 can indicate oversold conditions
Use this rsi workflow to quantify this scenario with deterministic inputs.
RSI works best with trend and volume confirmation
Use this rsi workflow to quantify this scenario with deterministic inputs.
Event reaction review
Recalculate rsi immediately after earnings, filings, or macro headlines.
Interpretation tips
- •Re-run rsi whenever key inputs change materially, not only when price moves.
- •Document assumptions so the same methodology can be repeated across watchlist names.
- •Use this metric as one layer in the decision stack, not as a standalone trade trigger.
Data caveats
- –Outputs are deterministic from your inputs; input quality determines output quality.
- –This page does not auto-adjust for broker fees, taxes, or slippage unless you include them in your assumptions.
- –Validate corporate action details, filing dates, and data freshness before acting on results.
FAQ
How does the rsi calculator work?
RSI Calculator is deterministic and uses only your inputs (close 1, close 2, close 3, close 4, close 5, close 6). Formula: RSI = 100 - (100 / (1 + RS)), where RS = Average Gain / Average Loss.
What does this output tell me in practice?
Calculate Relative Strength Index from sequential closing prices. Technical indicators are context tools, so combine them with trend, liquidity, and catalyst awareness.
Does the rsi calculator use real-time market feeds?
No. This page does not auto-pull live data. You control all inputs and can rerun instantly as market conditions change.
Can I use this result directly for trading decisions?
Use it as a planning layer. Combine with position sizing, liquidity, and catalyst context before any execution.
