Key strategies

Five strategies to start with — crossovers, bands, composition, position size, and candlestick patterns.

New to strategies? Read Strategies overview first. All 11 keys: Strategy catalog. Series wiring: Series and panels.

CROSS​

  • Key: CROSS
  • Pane behavior: renders on the main chart (newPane: false)
  • Default inputs: LINE = MACDLine, SIGNAL = MACDSignal, ONDN = Buy, ONUP = Sell
  • Output: one CROSS strategy series with field CrossValue
chart.addScript("CROSS");

Current definition notes:

  • the strategy checks whether two series crossed after resolving flat-equality runs backwards
  • the default input wiring makes it a practical MACD crossover strategy out of the box
  • the plotter uses a StrategyObject, so the result renders as signal markers rather than as a plain line

Use CROSS when you need a first signal generator that works from two existing series and already has sensible defaults.

EXCEED​

  • Key: EXCEED
  • Pane behavior: renders on the main chart (newPane: false)
  • Default inputs: UPPER = BBUpper, LOWER = BBLower, HIGH = h, LOW = l, ONDN = Sell, ONUP = Buy, SINGLE = false
  • Output: one EXCEED strategy series with field ExceedValue
chart.addScript("EXCEED");

Current definition notes:

  • the current registry treats a high above the upper band and a low below the lower band as the trigger conditions
  • the defaults line up with Bollinger-band outputs, so the key is usable without custom input wiring
  • SINGLE can suppress repeated identical signals on consecutive bars

Use EXCEED when you want a fast “price moved outside the band” signal without building the comparison logic yourself.

REBOUND​

  • Key: REBOUND
  • Pane behavior: renders on the main chart (newPane: false)
  • Default inputs: UPPER, LOWER, VALUE, ONDN = Sell, ONUP = Buy
  • Output: one REBOUND strategy series with field Rebound
chart.addScript("REBOUND");

Current definition notes:

  • the current controller detects a re-entry move back inside upper or lower bounds by comparing the current bar with the previous bar
  • unlike EXCEED, the series inputs do not ship with explicit default def mappings in the current registry
  • the output still uses a StrategyObject, so it is meant as a signal stream rather than a numeric overlay

Use REBOUND when you want the opposite side of an exceed-style workflow: a signal that fires on re-entry rather than on breakout.

MIX​

  • Key: MIX
  • Pane behavior: renders on the main chart (newPane: false)
  • Default inputs: FIRST, SECOND, and an editable MATRIX = FUSION.createSelectiveSignalsMatrix()
  • Output: one MIX strategy series with field Mix
chart.addScript("MIX");

Current definition notes:

  • the strategy reads two existing strategy series, converts their numeric values back to Fusion signal names, and resolves the final output through the matrix
  • unlike JOIN and DOUBLECHECK, the matrix is not read-only in the current definition
  • this key is more of a composition tool than a turnkey signal generator, so it becomes most useful when you can control its inputs

Use MIX when you need to merge two independent strategy streams into one custom decision table.

POSITION​

  • Key: POSITION
  • Pane behavior: opens a new pane (newPane: true)
  • Default inputs: STRATEGY, WEIGHT = 1, MULTIPLIER = 1.0
  • Output: one POSITION series with field Position
chart.addScript("POSITION");

Current definition notes:

  • the controller carries the previous position forward and reacts differently to Buy, Sell, Exit long, Exit short, and Exit all
  • MULTIPLIER is a conditional input, so it can be a constant or another series
  • this script is most useful once its STRATEGY input is wired to an actual signal-producing strategy

Use POSITION when you need a running exposure series rather than just discrete signal markers.

CANDLESTICKPATTERNS​

  • Key: CANDLESTICKPATTERNS
  • Pane behavior: renders on the main chart (newPane: false)
  • Default inputs: OPEN = o, HIGH = h, LOW = l, CLOSE = c, plus a CHOSENPATTERNS boolean list with all bundled patterns enabled by default
  • Output: one tooltip series with field CANDLESTICKPATTERNS
chart.addScript("CANDLESTICKPATTERNS");

Current definition notes:

  • the current output is a tooltipSeries, not a plain strategy series
  • the plotter type is CandlestickPatternStrategyObject, which matches its marker-style rendering
  • the built-in boolean list includes patterns such as MORNINGSTAR, EVENINGSTAR, HAMMER, DOJIUP, and DOJIDOWN

Use CANDLESTICKPATTERNS when you want prebuilt pattern scanning on top of the main price series rather than a generic numeric study.

Putting them together​

This is a practical first combination:

chart.addScript("CROSS");
chart.addScript("EXCEED");
chart.addScript("CANDLESTICKPATTERNS");

That gives you a crossover strategy, a band-break strategy, and a candlestick-pattern layer without leaving the built-in registry.

If you want to wire strategy inputs to custom indicator or strategy outputs, continue with Programmatic wiring.
