Key indicators

Five indicators that cover most first integrations: moving average overlay, volatility bands, RSI, MACD, and ATR.

Pick input series and panels in the UI — Series and panels. Full registry (97 keys): Indicator catalog.

EMA​

  • Key: EMA
  • Pane behavior: overlay on the main chart (newPane: false)
  • Default inputs: CLOSE, PERIODS = 14
  • Output: one EMA series rendered as a line
chart.addScript("EMA");

Current definition notes:

  • input series defaults to close (c)
  • plotter renders a line
  • default line color in the registry is #ff9800

Use EMA when you want the fastest first trend overlay without creating a new pane.

RSI​

  • Key: RSI
  • Pane behavior: opens a new pane (newPane: true)
  • Default inputs: CLOSE, PERIOD = 14, HI_BASELINE = 70, LO_BASELINE = 30
  • Output: RSI, RSIBaseHI, and RSIBaseLO
chart.addScript("RSI");

Current definition notes:

  • the pane shows the RSI line plus the upper and lower baseline guides
  • the indicator computes against close prices by default
  • the default baselines match the standard 70/30 interpretation

Use RSI when you need a separate momentum pane with explicit overbought and oversold guides.

MACD​

  • Key: MACD
  • Pane behavior: opens a new pane (newPane: true)
  • Additional pane behavior: centered around zero (centerZero: true)
  • Default inputs: CLOSE, FPERIOD = 12, SPERIOD = 26, SGPERIOD = 9
  • Output: MACDLine, MACDSignal, and MACDHistogram
chart.addScript("MACD");

Current definition notes:

  • the histogram uses Line and Histogram rendering in the current plotter config
  • the signal and main line render separately on top
  • the default setup is the common 12/26/9 MACD configuration

Use MACD when you want a multi-part oscillator with both line crossover and histogram context.

BBAND​

  • Key: BBAND
  • Pane behavior: overlay on the main chart (newPane: false)
  • Default inputs: CLOSE, PERIODS = 15, DEVIATIONS = 2.5
  • Output: BBUpper, BBLower, and BBMiddle
chart.addScript("BBAND");

Current definition notes:

  • the plotter renders the upper/lower band as a Band
  • the middle line renders separately as a line
  • the default period/deviation values come from the current registry, not from generic TA defaults

Use BBAND when you need price envelopes directly over the main chart rather than in a separate pane.

ATR​

  • Key: ATR
  • Pane behavior: opens a new pane (newPane: true)
  • Default inputs: HIGH, LOW, CLOSE, PERIODS = 12
  • Output: ATR
chart.addScript("ATR");

Current definition notes:

  • ATR uses high, low, and close by default
  • the current registry plots it as a line in its own pane
  • the indicator is a better fit for volatility context than for directional signals on its own

Use ATR when you need a simple separate-pane volatility measure to support stop sizing or regime checks.

Putting them together​

This is a practical first combination:

chart.addScript("EMA");
chart.addScript("BBAND");
chart.addScript("RSI");
chart.addScript("MACD");

That gives you two overlays on the main panel and two separate analysis panes below it.

If you need the broader registry, go back to Indicator catalog.
