SVE_TEMA_Typ TEMA Average on the typical price

Tema, Triple Exponential Moving Average was first introduced in Stocks & Commodities magazine February 1994 by Patrick Mulloy. Price is passed multiple times through the same filter and than combined.  


If you are looking for a good smoothing, but still fast reacting average on longer time periods, then the TEMA average is for you. The blue curve in the chart is a 20-period TEMA average on the typical price, using 30-minute bars. The typical price is the (High+Low+Close)/3.

for (i=limit;i>=0;i--) TemaBuffer[i]=3*Ema1[i]-3*Ema2[i]+Ema3[i];

If you create this indicator in MetaTrader, make sure you give it the name "SVE_TEMA_Typ", because we will call this function by this name from other indicators that we will present further on.

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.
