Indicator to color OHLC bars/candles based on volume and price action

Hi I need this indicator translated from pinescript (tradingview) to MQL4.

If the volume for the bar is below average the bar is GREY

if it is above average there are 4 variations:  

1. Close>Open, Close > High[1] -- Dark Green

2. Close<Open, Close < Low[1] -- Red

3. Close>Open, Close < High[1] -- Light Green

4. Close<Open, Close > Low[1] -- Orange

I need the volume histogram plotted the same colors with the SMA visible as well.
