Heikin-Ashi Smoothed
The Heikin-Ashi Smoothed study is based upon the standard Heikin-Ashi study with additional moving average calculations. The following is the calculation formula for the bars:
1. The current bar Open, High, Low, Close values are smoothed individually by using the moving average type specified by the Moving Average Type 1 Input with a length/period specified by the Moving Average Period 1 Input.
2. The Heikin-Ashi bar Open, High, Low, Close values are set using the smoothed values from step 1. This is performed using the standard Heikin-Ashi formula.
3. The final Heikin-Ashi Open, High, Low, Close values are calculated by doing a second smoothing of the bar values from step 2 by using the moving average type specified by the Moving Average Type 2 Input with a length/period specified by the Moving Average Period 2 Input.


If you choose to tick the box where it offers to use only one smoothed HA then it skips the third/final step and you do not need to choose the second MA type for it to work.
Remember, using FRAMA, always make sure you use even number for length.

For simple Heikin-Ashi, please tick single smoothed and DEFAULT (Not smoothed as there are no MA used)

Heikin-Ashi bars are calculated:
1. Close = (Open + High + Low + Close) / 4
This is the average price of the current bar.
2. Open = (Open of Previous Bar + Close of Previous Bar) / 2
This is the midpoint of the previous bar.
3. High = Max of (High, Open, Close)
Highest value of the three.
4. Low = Min of (Low, Open, Close)
Lowest value of the three.

Any questions/suggestions/errors or spelling mistakes? Please leave a comment and let me know. I will try to fix it.
This took me few days to finish, so I hope you will find it useful.

Would you like to have more MA type choices? Please comment down with any other which aren't included in this indicator and I will research them and add.

MA included in this script:

• * Tillson Moving Average (T3)
  * Double Exponential Moving Average (DEMA)
  * Arnaud Legoux Moving Average (ALMA)
  * Least Squares Moving Average (LSMA)
  * Simple Moving Average (SMA)
  * Exponential Moving Average (EMA)
  * Weighted Moving Average (WMA)
