True Fourier

True Fourier indicator is a powerful tool of technical analysis of financial markets at any time frame. It can be labeled to wave analysis which is realized by approximation of a given chart by Fourier series in this case. It should be noted that the classical Fourier expansion let one to perfectly approximate the chart but have no predictive force at all. The algorithm of True Fourier indicator is developed especially for financial market analysis and forecasting of price behavior.

A list of settings with particular recommendations is discussed in the manual which can be downloaded from the first message in comments.


  • Very simple in operation.
  • Lack of retardation: the indicator predicts price moving for long time in future and doesn't repaint.
  • Lack of artificial goals: we buy at minimums and sell at maximums. All the time in market.
  • The indicator determines time of trade instead of price. Thus you always know when the next signal will be.
  • Full manual is attached.


  • Why is it so expensive?
    I have a great experience on Forex and I consider the price to be adequate for the real working indicator-predictor. Besides there is no sense to sell good indicator for less price.

  • What is the difference between this indicator and all other indicators based on Fourier expansion which include even free indicators?
    As rule the very conventional Fourier expansion is used. True Fourier indicator is specially adapted for price charts analysis and for prediction price moving in future. Firstly nonorthogonal expansion is at the heart of the indicator. It is not quite Fourier but its much more complex analogue. Secondly the algorithm of searching of harmonics with separation on modes differs radically from conventional algorithm.

  • What are the minimal system requirements?
    In principle one can make calculations at any computer. But I recommend system based on Intel Core i3 and better or AMD Phenom X4 and better for comfortable work.

  • What is the average time of calculation?
    From 5 minutes to an hour at the setting which I usually use. One has to make recalculation once at several days at H1 time frame.

Version 1.1 - 2015.01.29
DynamicApproximation mode was corrected. It is recommended to carry out calculations with UseDynamicApproximation = true for the version 1.1 of higher.
