Hey,
Clear instructions. I'd be pleased to help you with this. My quote is $100 if no other complex options are added, and my turnaround between 1 and 2 business days.
The only difference in this case between before and after build 600 would be that in the prior version we cannot access the GMT time automatically, so you will need an user input for the time offset. I'm guessing the times in the CSV are GMT times. If the times match the broker's time, no problem whatsoever even on the old build.
Let me know if you're interested to talk more details.
Thanks,
Phillip,
