Overview

Supply/demand is a very famous trading method that helps traders gauge & takes advantage of trading actions made by BIG PLAYERS (like banks or funds), whose heavy positions seriously impact the market.

Unfortunately, each trader draws supply/demand zones differently. And ironically: when asked how they draw supply zones or demand zones, what their rules are - they even cannot answer with certainty and clarity. This makes it nearly impossible to code a great NinjaTrader 8 supply and demand indicator.

That's why ninZa.co set a quest to develop this challenging indicator for the NinjaTrader community. Supply/Demand Discovery, our success & pride, is one of the very rare supply and demand indicators for NinjaTrader 8, and perhaps the most accurate version! 

Why is our NinjaTrader 8 supply and demand indicator the superior version?

Because it does NOT repeat the mistake of most existing NinjaTrader supply and demand indicators: they all just draw supply/demand zones from market tops/bottoms. This mistake makes supply/demand nothing but support/resistance (we already have Market Extremes for support/resistance). However, a critical thing traders must understand is that: supply/demand and support/resistance are 2 different things, not one! 

Our NinjaTrader 8 supply and demand indicator truly reflects the mechanism of supply & demand - the 2 forces behind price discovery in all markets. Here are the correct definitions:

  • A supply zone is where the supply overwhelms the demand (sellers dominate). This makes the price PLUMMET.
  • A demand zone is where the demand overwhelms the supply (buyers dominate). This makes the price ROCKET.

As you see, supply/demand zones do not just show up at tops/bottoms. They may occur somewhere in the MIDDLE, which is the key difference to support/resistance.

Our awesome NinjaTrader 8 supply and demand indicator discovers supply/demand zones by searching for large moves happening within a very short period (on chart: you see the price rocket/plummet). It allows you to fully define the criteria of a large move (example: at least 3 ninZaATR within 3 bars, or at least 10 ninZaATR within 7 bars...).

Trading styles

Supply/Demand Discovery is extremely helpful for many common trading styles:

  • Reversal trading: If a false breakout occurs, the odd for seeing a successful reversal is very high.
  • Support and resistance: Supply and demand zones are natural support and resistance levels.
  • Stop loss and take profit: Always place your profit target ahead of a zone and set your stop order behind a zone.

To dig further on this important topic, please read the following great article → 6 Secrets for Supply/Demand Trading.

In this indicator, ninZaATR is used (instead of regular ATR) for better performance. For your information, ninZaATR is ninZa.co's special ATR version that helps improve indicator performance significantly on intraday charts. It is also a standalone FREE indicator for ninZaFamily → https://ninza.co/product/ninzaatr.

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.
