//input = price, user defined, default is closing price
//method1 = moving average (ma), user defined, default is WMA
//method2 = moving average (ma), user defined, default is EMA
//period1 = user defined, default is 4
//period2 = user defined, default is 13
//period3 = user defined, default is 13
//prev = previous, index = current bar number

prevP = price[index-1];
diff = price - prevP;
ma1 = ma(method1, index, period1, diff);
ma2 = ma(method2, index, period2, ma1);
Plot: wami = ma(method2, index, period3, ma2);
