Dear developer, I have purchased and install this indicator Seasonality MT4 Version 1.00 on my MT4, but nothing is displayed on the sub window except the product name. I am using MT4 Build 1401, which is the most updated version provided by the broker I am using, so update of the MT4 build is not the solution. If there is any additional settings required such as history data download or library files, please provide guidance, or consider to debug for use on other build of MT4. I hope for your reply, and support. Thank you.
