ticker

The ticker namespace creates identifiers for use with request.security(). Standard ticker identifiers use EXCHANGE:SYMBOL form. PyneCore supports Heikin Ashi requests; other synthetic chart types require tick-derived data and are not available.

Quick Example 

from pynecore.lib import close, request, script, ticker

@script.indicator("Heikin Ashi close")
def main():
    ha_symbol = ticker.heikinashi("BINANCE:BTCUSDT")
    ha_close = request.security(ha_symbol, "60", close)

Identifier Functions

new()

Creates an exchange-qualified identifier.

symbol = ticker.new("BINANCE", "BTCUSDT")  # "BINANCE:BTCUSDT"

If ticker already contains :, it is returned unchanged. The optional session, adjustment, backadjustment, and settlement_as_close arguments are accepted for Pine compatibility but do not alter PyneCore identifiers.

modify()

Returns the supplied identifier. Its optional session and adjustment arguments are accepted for Pine compatibility, but PyneCore data feeds do not expose per-request variants.

standard()

Returns the standard-chart identifier. With no argument it returns syminfo.tickerid; otherwise it returns the provided identifier.

inherit()

Builds an identifier for symbol using the exchange prefix from from_tickerid when symbol is not already qualified.

eth = ticker.inherit("BINANCE:BTCUSDT", "ETHUSDT")  # "BINANCE:ETHUSDT"

Chart Types

heikinashi()

Creates an identifier that request.security() evaluates as Heikin Ashi bars. The transform runs in the security context, after higher-timeframe aggregation. It works in historical and live mode. request.security_lower_tf() does not support synthetic chart types.

Unsupported synthetic chart types

ticker.renko(), ticker.pointfigure(), ticker.kagi(), and ticker.linebreak() raise NotImplementedError. These chart types require tick data that standard OHLCV inputs do not contain.

Compatibility

new(), modify(), standard(), inherit(), and heikinashi() are supported. Session and adjustment modifiers are intentionally no-ops; PyneCore has one data variant per supplied symbol and timeframe.
