🔧 Implementation Example

// Import the library
import andre_007/VolumeIndicators/3 as VOL

// Volume Moving Average with Hull MA
vma_value = VOL.vma(20, 6) // 20-period Hull MA of volume

// Money Flow Index with custom source
mfi_value = VOL.mfi(hlc3, 14) // MFI using HLC3 instead of close

// Volume Oscillator with EMA smoothing
vo_value = VOL.vo(12, 26, 2) // Fast=12, Slow=26, EMA smoothing

// Chaikin Money Flow
cmf_value = VOL.cmf(21) // 21-period CMF

// Volume Rate of Change
vroc_value = VOL.vroc(14) // 14-period volume momentum
