Adding the choice of which Moving Average to Plot on the Price Chart.

In the previous lesson we added a moving average to the chart. In lesson 3 we will provide the user of the indicator the choice of which moving average type plot in the user dialog box. This selected moving average will be plotted on the Price chart. We will learn about the enum C# function and switch statement ( which is a C# case statement). Finally, we will spend more time on the PLOT statement.

Just a note on the enum function used in NinjaScript Indicators. It is a great feature to allow the user to select from a list but internally there is a fair but going on, which will be explained in detail. If you have ever tried to save an indicator which has an enum as another name, on compilation you will get errors relating to a duplicate name. In this lesson, we will show you how to get around this problem.

Risk Disclosure: Futures and forex 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 ones’ financial security or life style. 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 Disclosure: 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.
