The formula for calculating the ESMA is as follows:
ESMA = pESMA - ( Smoothing Constant X ( pESMA - PRICE ) )
In the above formula:
ESMA is the new Exponentially Smoothed Moving Average.
pESMA is the Previous ESMA value.
PRICE is the value of the PRICE used for each bar, e.g. CLOSE

Note: A decimal value Smoothing Constant equal to 0.0 stops the ESMA from being displayed,
however, an ESMA will appear if the integer 0 is entered without the decimal point.
Weighted Moving Average Calculation
The CQG weighted moving average assigns weights linearly, assigning greater weights to more
recent data points.
Example:
A 21 period weighted moving average would be calculated as follows:
[21 * Close (0)] + [20 * Close (-1)] + [19 * Close (-2)] +…….[1 * Close (-20)]
