RSI Calculator
Calculate Relative Strength Index for technical analysis and trading signals
About this calculator
The RSI Calculator computes the Relative Strength Index, a momentum oscillator that measures the speed and change of price movements on a scale of 0 to 100. This essential technical analysis tool helps traders identify overbought conditions (typically above 70) and oversold conditions (typically below 30) in stocks, cryptocurrencies, and other securities. RSI values provide crucial insights for timing entry and exit points, making it invaluable for both day traders and long-term investors seeking to optimize their trading strategies.
How to use
Enter the closing prices for your chosen security over a specific period (typically 14 days). Input each price value in chronological order, starting with the oldest price first. The calculator will automatically compute the RSI value and display whether the asset is in overbought, oversold, or neutral territory based on standard RSI interpretation levels.
Frequently asked questions
What RSI values indicate buying or selling opportunities?
RSI values below 30 typically indicate oversold conditions (potential buying opportunity), while values above 70 suggest overbought conditions (potential selling opportunity). Values between 30-70 are considered neutral territory.
How many periods should I use for RSI calculation?
The standard RSI period is 14 days, which provides a good balance between sensitivity and reliability. Shorter periods (7-10) offer more signals but increased volatility, while longer periods (21-25) provide smoother, less frequent signals.
Can RSI be used for all types of financial instruments?
Yes, RSI works effectively across various financial instruments including stocks, forex, commodities, cryptocurrencies, and indices. The calculation method remains consistent regardless of the asset type or market being analyzed.
