Use currentSymbol and currentExchange instead of hardcoding values for maximum flexibility.
// Good: source("ohlcv", currentSymbol, currentExchange)Cache Expensive Operations
Store references to commonly used data sources to improve performance.
timeseries ohlcv = source("ohlcv", currentSymbol, currentExchange);Array Variables
Core variables that handle collections of data for multi-dimensional analysis.
colorcolorThe color to use for plotting (e.g., 'red', 'blue')
Example:
plotLine(ema20, ["blue"], 2);color[]color[]Storing an array of color
