Frequently Asked Questions
Q. What does RSI above 70 mean?
RSI (Relative Strength Index) above 70 indicates an overbought zone, suggesting a higher probability of a short-term price correction. It is not a definitive sell signal, but it warrants tighter risk management.
Q. How do I interpret MA7 and MA25?
When MA7 (7-day moving average) crosses above MA25 (25-day), it is called a Golden Cross — a bullish signal. When it crosses below, it is a Death Cross — a bearish signal. Price trading above MA25 suggests an uptrend; below suggests a downtrend.
Q. How are support and resistance levels calculated?
Support is a price level where the price repeatedly bounced upward; resistance is where upward momentum repeatedly stalled. This tool automatically detects these levels using a local minima/maxima algorithm.
Q. How often is the chart data updated?
Data is fetched from the CoinGecko free API each time you select a coin or timeframe. This is not real-time tick data — it uses aggregated OHLC candles (minutes to hours depending on the timeframe).
Q. Can I use this analysis for investment decisions?
This tool provides technical analysis for reference only and does not constitute investment advice. Cryptocurrency trading carries a risk of loss — always conduct your own research and apply proper risk management.

Expert Knowledge: Crypto Technical Analysis Chart — Live RSI, MA & Support/Resistance
Technical Analysis (TA) is the study of past price data to forecast future price movements. Originating from Charles Dow's Dow Theory in the 1880s, it has evolved into hundreds of indicators — RSI, MACD, Bollinger Bands, and more — widely used by professional traders today.
Moving Averages (MA) are among the most reliable indicators. MA7 captures short-term momentum, while MA25 reflects medium-term trend direction. Historically, BTC Golden Crosses (MA7 crossing above MA25) have preceded average gains of 37%, while Death Crosses have signaled major drawdowns.
RSI(14) ranges from 0 to 100. Above 70 is overbought; below 30 is oversold. However, in strong bull markets, RSI can stay above 70 for extended periods — the "overbought persistence" effect. Never rely on RSI alone; combine it with MA crossovers and support/resistance analysis for higher-confidence signals.
