This indicator beautifully plots the volume delta of each bar, which is the difference between the total buy volume & the total sell volume of a bar. This is a SUPER IMPORTANT indicator used by successful trading professionals, and it can be a great fit for any trading system.

More wonderfully, ninZa.co's Volume Delta indicator allows you to filter volumes by specifying a preferred range of volume sizes, so that you can track the footprints and know the behaviors of a special group of traders. Here are some sample volume filters that you can set up:

• Volumes from 1 to 5: Retail traders
• Volumes from 6 to 19: Big professional traders
• Volumes from 20 to 999999: Banks & hedge funds

The indicator lets you define 4 thresholds for strong & moderate volume delta. For example, you can set them as:

• Strong positive delta: 150
• Moderate positive delta: 50
• Moderate negative delta: -50
• Strong negative delta: -150

Then the indicator will print markers and trigger alerts to notify you of important shifts in volume delta.

• Display volume delta of each bar as an elastic ribbon at chart bottom (automatically adjusts to fit your bar spacing)
• Offer 3 modes of volume base for selection: BidAskPrice_RealVolume, UpDownTick_RealVolume, UpDownTick_UnitVolume
