  7. // Purpose: Draws Traditional Pivots lines at the timeframe specified.
  8. // Has logic that only displays the next pivot instead of all the pivots (for the purpose of chart de-cluttering).
  9. // TradingView has a limit of 40 security calls per script. Due to this limitation this script can only display pivots a max of 7 time periods back.
  10.  
  11. // Usage: Add indicator. Choose timeframe, number of timeframes back in the past to display, line color, line weight
