Hello,
I'm from Vietnam.
I'm an experienced MT4 & MT5 Coder and Forex Trader. I was on the Market more than 6 years till now.
Regarding your project, I completely understand your problem.
Some days ago, I have corrected an FFCal Indy version and it worked well. I will correct directly on your Indy version to be sure it will work as original version.
Thank you and I'm looking forward to working with you!.
