FAQ for dummies



This product is much less complicated and sophisticated than your other products. 

Have you got a more advanced version of this for expert traders? 














I have provided a simple product to satisfy the customers who are learning. This does not mean an expert cannot profit from it.


A very famous trader featured in Market Wizards No1 used a similar method with exceptional results and his name was Martin Schwartz, a man who was just about as far from being a beginner as any man could be.


I recall he won the New York Times trading championship a few times in a row and made more money than all the other contestants combined.





The wheel:

A simple invention from 5,500 years ago




Surprisingly wheels are used on the Airbus A 380 the worlds most sophisticated passenger jet today.




Do you have instructions for the Percent Asymmetrical Indicator?








Yes, they are here, reading them slowly will enhance your knowledge --------->










Does Percent Asymmetric Stop work with Kagi, Renko and tick charts?






Yes it works with any type of charts in MultiCharts ---->




It works fine on any charts in MultiCharts



I wonder if you can tell me the best time frame chart to use Percent Asymmetric Method?







As this product uses percentages to activate trades it is not relevant what time frame chart is used.


If you use a 1 minute chart set to 2% it will give the same signals on a 30 minute chart set to 2%


Looking for the holy grail?    Its turns out to be a stopwatch ( sometimes )---->

....But in this case it does not matter



When will Percent Asymmetric for MetaTrader 4 be released?








I am currently porting Pi-Osc over to MT4 and Percent Asymmetric will follow shortly after.


I guess around March 2016 but please check the home page for exact release dates..



The Pi-Osc for MT4 is shown here


Piosc MT4







How do I find my MultiCharts customer details?









Open MultiCharts, click on help, about, and your details are shown there. Please copy and paste this into your Paypal order when you purchase. 




What happens when my license expires? Are there any obligations to me?







You will get a notification message like this------->

On your MultiCharts platform showing the license has expired

You can renew your license if you wish but are not obligated to do so.


Nothing bad happens, it just stops working


I day trade mostly on the 1 minute charts of ES and NQ and close out before the end of the day. Is this Percent Asymmetric suitable to use on a 1 minute time frame? I see you have some 10 minute FDAX screen shots on your site but most are longer time frames.


Yes it will work but if you are planning to use Percent Asymmetric for day trading you will likely end up in the group of the 90% of day traders who lose. (Day trading = close out all trades before the end of the day)

Such ill advised preparation and research generally results in outcomes such as shown in the video clip.

  • Futures, Forex and Stock trading contain substantial risk and are not for every investor.

  • An investor could potentially lose all or more of the initial investment.

  • Risk capital is money that can be lost without jeopardizing ones financial security or lifestyle.

  • Only risk capital should be used for trading

  • 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.
