Dear All,
This problem was introduced on December 15 2016 and went undetected . ChaikinAD was only returning either 0 or 100 instead of a range of numbers from -100 to 100. ChaikinMFP was also affected since it uses ChaikinAD
The problem has been fixed.
Please re-run your portfolio rebalances or simulations if you use these functions in the rules or ranking.
We’re very sorry about this.
