CryptoVN - HawkEye Volume Indicator

This is HawkEye volume clone by @LazyBear:


I've modified:
- Use ema instead of sma
- Added plot name and vol MA
- Used to Pine Script version 3

(*)Volume bars:

• Green bars: Signify BUYER (Bullish)
  
• Red bars: Signify SELLER (Bearish)
  
• White bars: Signify BUYERS = SELLERS (neutral)
