What does the chart say?
- Technical Indicators
Moving Average (SMA)
Average of the last N closing prices — a smoothing line that filters out day-to-day noise so the trend shows up.
- Technical Indicators
Exponential Moving Average (EMA)
A moving average that weights recent prices more heavily — reacts faster than a simple moving average.
- Technical Indicators
Relative Strength Index (RSI)
A momentum gauge from 0 to 100 — how much the recent gains weigh against the recent losses.
- Technical Indicators
MACD (Moving Average Convergence Divergence)
Twelve-day EMA minus 26-day EMA, with a 9-day EMA signal line — built to highlight changes in trend direction.
- Technical Indicators
Support & Resistance
Price levels the stock has tended to bounce up from (support) or pull back down from (resistance) in the past.
- Technical Indicators
Fibonacci Retracement
Horizontal lines drawn between a recent high and low at 23.6%, 38.2%, 50%, 61.8%, and 78.6% — areas chart-watchers expect price attention to return to.
