Added:
Calc_vw_omega(rets, vols, L)
  Computes the Volume-Weighted Omega Ratio over historical return & volume arrays
  Parameters:
    rets (array<float>): Array of period returns
    vols (array<float>): Array of period volumes (or dollar volume weights)
    L (simple float): Threshold/hurdle return (e.g., 0.0 or risk-free rate per period)
  Returns: Volume-weighted Omega ratio

Calc_vw_cvar(rets, vols, a)
  Computes Volume-Weighted Conditional Value-at-Risk (Expected Shortfall)
  Parameters:
    rets (array<float>): Array of period returns
    vols (array<float>): Array of period volumes (or dollar volume weights)
    a (simple float): Tail risk alpha level (e.g., 0.05 for 95% CVaR)
  Returns: Volume-weighted average loss in the left alpha tail

Get_history_arrays(sym, len)
  Fetches synchronized historical returns and volumes into fixed-length arrays
  Parameters:
    sym (simple string): Security ticker string (e.g., "AMEX:SPY")
    len (simple int): Rolling window length
  Returns: [returns_array, volumes_array]
