Market data

A NeuroScript indicator runs candle by candle over the market data. On every candle, the variables below point to the value of that candle, and the script is re-evaluated from the start.

OHLCV

The five base series of the current candle, all series<float>:

//@version=6
indicator("Candle body", overlay=false)
corpo = close - open
plot(corpo, "Body", color=corpo >= 0 ? color.green : color.red)

Historical series

Every series keeps the values of previous candles. Use [n] to look n candles back ([0] is the current candle, same as using no index):

anterior = close[1]          // close of the previous candle
variacao = close - close[1]  // change from the previous one
ha10 = close[10]             // close 10 candles back

Derived prices

Common shortcuts, already computed on every candle (series<float>):

// moving average over the typical price instead of the close
avg = ta.sma(hlc3, 20)

Time and bar index

// highlights the first 50 candles of the chart
inicio = bar_index < 50
plot(inicio ? high : na, "Start", color=color.orange)

Missing values (na)

na represents "no value" — it shows up in lookback beyond the available history or in calculations that aren't ready yet. Plotting na simply draws nothing on that candle, which is useful for conditional signals:

// only marks when it closes above the previous high
rompimento = close > high[1] ? high : na
plot(rompimento, "Breakout", color=color.green, style="circles")

Timeframe and symbol

Information about the chart's timeframe and the asset lives in the timeframe.* and syminfo.* namespaces. The details go into the reference along with the other namespaces.
