Calculation

//input = price user defined, default is close
//avPeriod = user defined, default is 28
//taiPeriod = user defined, default is 5
//sma = simple moving average, index = current bar number

av1 = sma(index, avPeriod, input);
highest = highest(index, taiPeriod, av1);
lowest = lowest(index, taiPeriod, av1);
Plot: tai = (highest - lowest) * 100 / price;
