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.

Just got your new Supply/Demand Discovery and it is truly a great improvement over everything else on the market. It will take me days to determine the best values for the variables for my different charts, but it will be worth the effort.

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.
