Common ScriptBase Reference

Indicators and strategies inherit common behavior from the HyperionX script base. This page covers the shared members used by both.

Primary Series

Member	Type	Description
`Open`	`ISeries<double>`	Current input open prices.
`High`	`ISeries<double>`	Current input high prices.
`Low`	`ISeries<double>`	Current input low prices.
`Close`	`ISeries<double>`	Current input close prices.
`Volume`	`ISeries<double>`	Current input volume values.
`DateTime`	`ISeries<System.DateTime>`	Current input bar timestamps.
`Input`	`ISeries<double>`	Selected input series.

Use System.DateTime.Now or System.DateTime.UtcNow for clock time. In script context, DateTime is the bar timestamp series.

Member	Description
`Opens`	Open series list by data series index.
`Highs`	High series list by data series index.
`Lows`	Low series list by data series index.
`Closes`	Close series list by data series index.
`Volumes`	Volume series list by data series index.
`DateTimes`	Timestamp series list by data series index.
`CurrentBars`	Bar count by data series index.

Primary data is index 0. Extra series are index 1 and above.

Member	Description
`Instrument`	Current instrument object.
`Connection`	Current connection object.
`ConnectionName`	Display name of the active connection.
`TickSize`	Instrument price increment.
`Multiplier`	Instrument multiplier.
`DataSeries`	Display data series string.

Member	Description
`Draw`	Built-in drawing helper.
`Ctx`	Structured script context.
`Plots`	Runtime plot collection.
`IsAutoscale`	Applies autoscale behavior to script plots.
`BarBrush`	Sets current bar color.
`BackBrushAll`	Sets current bar background color.

BarBrush and BackBrushAll are protected, so they are used from inside derived scripts.

Method	Purpose
`AddDataSeries(DataSeriesType type, int value, string symbol = "")`	Adds a secondary series or instrument.
`AddSeries(ISeries<double> series)`	Registers a custom output series.
`AddPane(string paneName = "")`	Creates a chart pane.
`AddPanePlot(Plot plot)`	Adds a plot, normally to a pane.
`AddPanePlot(PaneControl pane, Plot plot)`	Adds a plot to a specific pane.
`RemovePlots()`	Removes plots owned by the script.
`RemovePanes()`	Removes panes owned by the script.
`InvalidateChart()`	Recalculates chart extremes and redraws.
`InvalidateChartVisual()`	Redraws without recalculating candle or indicator scale state.
`Print(object message)`	Writes to debug output.
`Log(object message)`	Writes to platform log output.
`ClearDebug()`	Clears debug messages.
`SendMail(string to, string subject, string body)`	Sends email through configured email service.
`ToTime(System.DateTime time)`	Converts time to integer time format.

Use [HyperionXProperty] for editable parameters.

[HyperionXProperty]
[Display(Name = "Period", GroupName = "Parameters", Order = 1)]
public int Period { get; set; }

The runtime tracks:

These are mostly used by property grids, optimizers, validation workflows, and AI tooling.

Ctx is the newer structured API. It groups script capabilities by intent:

Context	Purpose
`Ctx.Chart`	Visible range, price range, coordinate transforms, chart invalidation.
`Ctx.MarketData`	Symbol, candles, depth, bid, ask, spread, bar timing.
`Ctx.Drawing`	Fixed HUD text, drawing existence checks, drawing removal.
`Ctx.Orders`	Strategy order helpers.
`Ctx.Account`	Account balances, orders, positions.
`Ctx.Position`	Current position state.
`Ctx.Log`	Print, info, debug, and error output.
`Ctx.Runtime`	State, current bar, bars in progress, calculate mode, optimization flag.
