  1. // Using pivots, counters and arrays to determine 'long-term' highs & lows (those nested between Intermediate term highs&lows, which themselves are nested between short term highs&lows)
  2. // Applying 'Spikeyness' filter to filter out weak Pivot highs/lows (default toggled ON)
  3. // Added Alerts; added display table.
  4. // Added optional Lines (self-terminating when hit by price)
