Everything is possible. I've found the math on the following page: https://www.motivewave.com/studies/smi_ergodic_oscillator.htm
//price (user defined, default is closing price)
//method = moving average (user defined, default is EMA)
//prevP = previousPrice, index = current bar number
//abs = absolute value
//ma = moving average
prevP = price[index-1];
change = price - prevP;
absChange = abs(price - prevP);
tempChange = ma(method, index, fastPeriod, change);
tempAbsC = ma(method, index, fastPeriod, absChange);
tempChange = ma(method, index, slowPeriod, tempChange);
tempAbsC = ma(method, index, slowPeriod, tempAbsC);
SMI = tempChange / tempAbsC;
SIGNAL = ma(method, index, sigPeriod, SMI);
Plot: SMIEO = SMI - SIGNAL;
The difficulty may be that you need to combine multiple indicators to create the output value. But this has been done before in the ADX indicator: https://github.com/anandanand84/technicalindicators/blob/master/src/directionalmovement/ADX.ts
Is it possible to create this indicator?
If anyone knows how to create in javascript can help me?
