I created an indicator which suits my scalping needs.
First it calculates the mid point of every candle, then it calculates where the closing price is in the candle and converts that to a percentage from the mid point. Then it looks at volume and calculates the difference (Positive/negative) from the previous volume bar and converts that to a percentage. These 2 factors are summed together to give a percentage number (positive or negative) then highlights the positive value. Bullish volume and price action turn to gold.
I use this for scalping to great effect. Enjoy.
