This update is a correction on the way the Fib Zero line is calculated. Previously it was just based on the source of the previous day, which is Ok as long as the Fiblength was set to 2. The new version calculates the Fib Zero from the average of the specified source over the Fiblength, so if Fiblength is now something other than 2 the Fibonacci Zero and other support and resistant levels should calculate correctly.
