Advanced Scripting – MTF Data, Sessions & Hover Collisions

Multi-Timeframe Data (ctx.get_timeframe_data)

Requests and matches technical indicator series calculated on higher resolutions (MTF) aligned to the current chart timeframe.

const dailyEma = ctx.get_timeframe_data(syminfo.ticker, '1D', 'ema', 200);

Trading Sessions (ctx.session.in_range)

Validates if a specific unix milliseconds timestamp falls within a target trading session range (e.g. Regular Trading Hours).

const nycSession = ctx.session.in_range(bar.time, "0930-1600:23456");
bgcolor(nycSession ? color.new(color.blue, 90) : na);

Collision & Hover Checks (ctx.is_hovered)

Returns true if the user's cursor currently floats over a bounding rectangle defined around a specific bar index and price level.

if (ctx.is_hovered(bar_index, close, 15, 15)) {
  // Render interactive tooltips, highlights, or overlays
}

Indicator Panes (ctx.pane)

Setting this variable to 'new' forces the script indicator to render in an isolated horizontal pane below the main grid (like standard oscillators: RSI, MACD). This is transpiled automatically when utilizing study declarations with overlay=false.

ctx.pane = 'new'; // Oscillates on its own chart pane

Alerts (ctx.alert)

Triggers custom interactive toast alerts and logs conditions during real-time loops. This wrapper is capped internally to execute only once per bar update to prevent duplicate flood.

ctx.alert("Bullish Breakout!", close > resistanceLevel);

Helper Variables & Functions

Pine Script-style helper variables and safety functions natively mapped inside the custom transpiler:

na(val)

Returns true if a value is null, undefined, or NaN.

nz(val, replacement)

Safely returns the value if defined and valid, otherwise returns the replacement (defaults to 0).

hour(time, timezone)

Extracts the hour component (0-23) from a timestamp in a specific timezone context (e.g. 'local' or 'UTC').
