#hint: <b>Fibonacci Fan lines</b>
Fibonacci Fan lines are trend lines based on Fibonacci retracement points. Rising fan lines extend up from a trough and pass through retracement based on the advance (lowest low to highest high or on the falling fan lines: highest high to lowest low). These fan lines can then be used to estimate support levels or potential reversal zones. Falling fan lines can then be used to estimate resistance levels or potential reversal zones.
#hint Price: Price used in the alerts on crossing of the fans. <b>(Default is Close)</b>
#hint onExpansion: Determines if the fan lines are projected past the current bar into the right side expansion <b>(Default is Yes)</b>
#hint Coefficient1: Fan Line 1: Trough to 38.2% retracement on rising fans.
Peak to 38.2% Coefficient on falling fans. <b>(Default is 38.2%)</b>
#hint Coefficient_2: Fan Line 2:

Above what you see is an aggregate version of auto Fib Fans that measures the high and low of price of the previous aggregation be it the month quarter year etc. I have found it to be an amazing indicator but my only problem is that the code is not inputting the correct highs and lows of the previous aggregation due to incorporating "highestall" and "barnumber" as part of the code. Been trying to find a workaround this but everytime I mess with the code it goes form angled to horizontal lines. Was hoping the community would be able to assist in this. The Fibs shown are what I found to so far be the best lines to use, but if anyone finds a better set of lines then by all means would love to hear it.

Also as a side note from my experience is that aggregations of quarters like the quarter and yearly seem to be the best aggregations since I personally believe and from what I have read is that the quarterly is when algos and hedge funds seem to reset or adjust positions. May be totally wrong but from what I have seen it seems to be logical.

Hey Ben, Can you please create a shareable link for this study: The Fibonacci Fan Lines. I keep receiving an error message showing two invalid statements; see attached picture...Thanks

Rich (BB code):`#hint: <b>Fibonacci Fan lines</b> Fibonacci Fan lines are trend lines based on Fibonacci retracement points. Rising fan lines extend up from a trough and pass through retracement based on the advance (lowest low to highest high or on the falling fan lines: highest high to lowest low). These fan lines can then be used to estimate support levels or potential reversal zones. Falling fan lines can then be used to estimate resistance levels or potential reversal zones. #hint Price: Price used in the alerts on crossing of the fans. <b>(Default is Close)</b> #hint onExpansion: Determines if the fan lines are projected past the current bar into the right side expansion <b>(Default is Yes)</b> #hint Coefficient1: Fan Line 1: Trough to 38.2% retracement on rising fans. Peak to 38.2% Coefficient on falling fans. <b>(Default is 38.2%)</b> #hint Coefficient_2: Fan Line 2: Trough to 50% retracement on rising fans. Peak to 50% Coefficient on falling fans. <b>(Default is 50%)</b> #hint Coefficient_3: Fan Line 3: Trough to 61.8% retracement on rising fans.
