Calculation

//period = user defined, default is 50
//prev = previous, MT = moreThan, LT = lessThan
//index = current bar number

highest = highest(index, period, high);
lowest = lowest(index, period, low);
Plot: tl = (highest + lowest) / 2;
//Signals
prevHigh = high[index-1];
prevLow = low[index-1];
prevTl = tl[index-1];
sell = (prevTl MT prevHigh AND tl LT high );
buy = (prevTl LT prevLow AND tl MT low);
