Lines that connect the close of candles for a specific period with the close of the last closed candle. After this when the new candle forms , these lines can act as a sr/trendlines (but in a different way as you can see), and i think that they are more accurate than trendlines . Also another idea would be if the lines would be extended forward or lets say you add two periods and with that you see the intersection of the candle close lines for those two periods. For now some help would be nice to make the code function properly (when a new candle forms it doesn't move forward) and to add more features if possible (like extended lines, or double periods, or other ideas welcome..)
