Chaikin Oscillator - indicator for MetaTrader 5

Chaikin Oscillator is named after its author Marc Chaikin and based on the Accumulation/Distribution indicator and a number of Joe Granville and Larry Williams works.

The presented variant of this popular indicator allows to select the smoothing algorithm out of ten possible variants:

1. SMA - simple moving average;
2. EMA - exponential moving average;
3. SMMA - smoothed moving average;
4. LWMA - linear weighted moving average;
5. JJMA - JMA adaptive average;
6. JurX - ultralinear smoothing;
7. ParMA - parabolic smoothing;
8. T3 - Tillson's multiple exponential smoothing;
9. VIDYA - smoothing with the use of Tushar Chande's algorithm;
10. AMA - smoothing with the use of Perry Kaufman's algorithm.

It should be noted that Phase parameter has completely different meaning for different smoothing algorithms.

• For JMA it is an external Phase variable changing from -100 to +100.
  
• For T3 it is a smoothing ratio multiplied by 100 for better visualization;
  
• For VIDYA it is a CMO period, for AMA it is a slow EMA period;
  
• For AMA fast EMA period is a fixed value and is equal to 2 by default. The ratio of raising to the power is also equal to 2 for AMA.

The indicator uses SmoothAlgorithms.mqh library classes (must be copied to the terminal_data_folder\MQL5\Include). The use of the classes was thoroughly described in the article "Averaging Price Series for Intermediate Calculations Without Using Additional Buffers".
