Please read Trader Manual to understand how this indicator works.
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 in order flow analysis by successful trading professionals, and it can be a great fit for any trading system.

More wonderfully, ninZa.co's Volume Delta indicator for NinjaTrader 8 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 – an essential signal for those relying on trading volume analysis.

If you'd like to explore further, we have a wide range of NinjaTrader 8 indicators that may be a good fit for your trading approach.

Indicators Improved My Charts. Hannah's Help And Great Customer Service. Will Buy Again.

I have been using the ninZa.co indicators for several months now and am very happy with what a valuable addition they have been to my charts. I recently decided to add one of the recently released indicators from ninZa.co. But after using for a few days, it wasn’t quite what I had been looking for. I contacted ninZa.co and had the pleasure of working with Hannah for an exchange to a different one of the many available indicators. At the time, the indicator I wanted to purchase to replace the one I had recently bought was on sale. Hannah put through an exchange and without my having to ask, gave me the advantage of the sale price. She also included a pdf that provided education about the indicator I chose to switch to. Any time I have had contact with one of the associates from ninZa.co, I have received excellent customer service, and will not hesitate to purchase from them again.

Awesome Indicator And Pi Rocks

This is my story, I ordered the Day Range indicator for NIFTY India. To my dismay, it didn't work well as it calculated ranges in ticks. I asked Larry Pi if there was a workaround, and he created a new version with all the choices for range unit: points, ticks, pips. He was with me all through the process, with very short turnaround cycles. So don't hesitate at all to pick what you want! You won't regret.

Futures, foreign currency, and options trading contains substantial risk and is not for every investor. An investor could potentially lose all or more than the initial investment. Risk capital is money that can be lost without jeopardizing one's financial security or lifestyle. Only risk capital should be used for trading and only those with sufficient risk capital should consider trading. Past performance is not necessarily indicative of future results.

Hypothetical performance results have many inherent limitations, some of which are described below. No representation is being made that any account will or is likely to achieve profits or losses similar to those shown; in fact, there are frequently sharp differences between hypothetical performance results and the actual results subsequently achieved by any particular trading program. One of the limitations of hypothetical performance results is that they are generally prepared with the benefit of hindsight. In addition, hypothetical trading does not involve financial risk, and no hypothetical trading record can completely account for the impact of financial risk of actual trading. For example, the ability to withstand losses or to adhere to a particular trading program in spite of trading losses are material points which can also adversely affect actual trading results. There are numerous other factors related to the markets in general or to the implementation of any specific trading program which cannot be fully accounted for in the preparation of hypothetical performance results and all which can adversely affect trading results.
