S027

An ohlcv subscription that inherits the chart's exchange, symbol, and timeframe defines the chart's bars and its history replay, so it cannot ask for live data only. Drop history: from it, or give the live-only subscription its own timeframe.

Failing example

script "conf"

data chart = subscribe(data.ohlcv, history: 0s)

Corrected example

script "fixed"
data chart = subscribe(data.ohlcv)
data clock = subscribe(data.ohlcv, timeframe: 1s, history: 0s)
