getDailyClose(offset)
  Returns the daily close for a specific offset.
For each offset value (from 1 to 21), the function uses a static request.security() call
to retrieve the daily close from the previous day at the specified offset.
  Parameters:
    offset (int): (int) The offset value (from 1 to 21) representing the desired close value.
  Returns: (float) The daily close for the specified offset or na if offset is out of range.

isVolumeAboveThreshold(vol, mediaPeriod, thresholdPercent)
  Checks if the current volume is above the threshold based on its moving average.
The threshold is calculated as the average volume plus a percentage increment.
  Parameters:
    vol (float): (series float) The volume series (e.g. the chart volume).
    mediaPeriod (int): (int) The period for calculating the moving average.
    thresholdPercent (float): (float) The percentage to add to the average for the threshold.
  Returns: (bool) True if the volume exceeds the threshold, false otherwise.

calcPvsra(pvsraVolume, pvsraHigh, pvsraLow, pvsraClose, pvsraOpen, redVectorColor, greenVectorColor, violetVectorColor, blueVectorColor, darkGreyCandleColor, lightGrayCandleColor)
  Calculates the PVSRA candle color, determines if a vector candle has appeared,
and returns additional support parameters (average volume, volume spread, highest volume spread).
- "High" (Climax): volume >= 200% of the average OR (volume * candle spread) >= highest spread over the previous 10 bars.
-> Bull candle: green; Bear candle: red.
- "Medium": volume >= 150% of the average.
-> Bull candle: blue; Bear candle: violet.
- Otherwise, default (non-vector) candle colors are used.
  Parameters:
    pvsraVolume (float): (series float) Volume series.
    pvsraHigh (float): (series float) High price series.
    pvsraLow (float): (series float) Low price series.
    pvsraClose (float): (series float) Close price series.
    pvsraOpen (float): (series float) Open price series.
    redVectorColor (simple color): (simple color) Color for bearish candle in high scenario.
    greenVectorColor (simple color): (simple color) Color for bullish candle in high scenario.
    violetVectorColor (simple color): (simple color) Color for bearish candle in medium scenario.
    blueVectorColor (simple color): (simple color) Color for bullish candle in medium scenario.
    darkGreyCandleColor (simple color): (simple color) Color for bearish candle in non-vector situation.
    lightGrayCandleColor (simple color): (simple color) Color for bullish candle in non-vector situation.
  Returns: (tuple) A tuple containing: [pvsraColor (color), alertFlag (bool), averageVolume (float),
volumeSpread (float), highestVolumeSpread (float)].
