UltraFatl - MetaTrader 5 Script | Forex Indicator Download - MT4/MT5 Resources

The indicator is based on the Fatl indicator value and its signal line analysis. The signal line calculation algorithm is as follows. The period of each signal line is calculated by the arithmetic sequence formula:

Signal period (number) = starting length + number * step size

The value of the numeric variable ranges from 0 to StepsTotal. The Fatl indicator values ​​for different periods are used to calculate the average value of the Fatl indicator. The calculation of the current trend direction is based on the average trend value of all signal lines.

Finally, the positive and negative values ​​of the trend are averaged and used as indicator lines, displayed as a color histogram, using the DRAW_COLOR_HISTOGRAM2 painting style. The histogram color depends on the trend direction and the histogram width depends on the trend strength.

For each trend direction, 4 colors are used in the histogram. For indicator values ​​outside overbought and oversold levels, dark colors are used. For overbought/oversold values, use lighter colors.

The indicator can be smoothed by choosing from a dozen possible versions:

It should be noted that the Phase1 and Phase2 parameters have completely different meanings for different smoothing algorithms. For JMA, it is an external phase variable that varies from -100 to +100. For T3, it is the smoothed ratio multiplied by 100 for better visualization; for VIDYA, it is the CMO oscillation period; for AMA, it is the slow EMA period. In other algorithms, these parameters do not affect smoothing. For AMA the fast EMA period is a fixed value, equal to 2 by default. For AMA, the ratio of raised powers is also equal to 2.

The indicator uses the SmoothAlgorithms.mqh library class (must be copied to terminal_data_folder\MQL5\Include). The use of the class "Average price series for intermediate calculations without using additional buffers" is described in detail in the article.
