text: Title: VWMA calculation is werid
  Body: I think VWMA calculation is werid, since it does not take the **weighted by recent value** into consideration.
  It uses
  
  ```python
  pv = close * volume
  vwma = sma(close=pv, length=length) / sma(close=volume, length=length)
  ```
  
  for wma calculation [check out this](https://www.fidelity.com/learning-center/trading-investing/technical-analysis/technical-indicator-guide/wma), it should use the same with adding volume as an additional parameter
  
  ```python
  WMA = (P1 * 5) + (P2 * 4) + (P3 * 3) + (P4 * 2) + (P5 * 1) / (5 + 4+ 3 + 2 + 1)
  VWMA = ?
  ```
  right? what do you think?
  
  
  TradingView is using the same as the current calculation https://www.tradingview.com/pine-script-reference/v3/#fun_vwma
  
  Maybe:
  WMA is weighted by recent value
  VWMA is weighted by volume without of recent value
  
  if that is the case. then please feel free to close this
