Hello traders,
This indicator shows volume changes in percentage over the past periods as well as Bollinger Bands of volume changes with +2σ band.
The formula to calculate volume changes is;
(Today’s volume / average volume of past n periods ) *100
** n is user input
Bar color changes to green if close >= open, else if red.(You can change colors.)
Bollinger band The reason I included Bollinger band here is if volume changes crosses over +2σ bands, that would suggest strong buying or selling pressure behind which might contribute price surging or dropping.
The following chart is BTCUSD daily chart.
Some correlation between volume changes and price movement can be observed. For example, when volume changes surpasses BB+2σ with green bar, bullish trend occurs while in case of red bar, bearish trend happened.
Signal/Alert Signal can be shown when volume changes cross over BB +2σ or upper band.(% changes, user input) Alert condition is same.
