Hi, I have two questions about the period converter
1) The file format that it writes looks strange, if opened directly. Is there a guide to reading it? Is it in a language other than English, or compressed or something. Here is a brief sample from the top of the file for EURUSD 1 minute data:
Copyright © 2005, Alpari Ltd.EURUSD'Ð@ |aó?@aó?àMbó?ÀMbó?.@@'Ð@ÀMbó?åaó?À¶bó?ÀMbó?$@|'Ð@ÀMbó? Ø_ó?àMbó? Ø_ó?5@¸'Ð@€A`ó
2) While running it, how would I extract moving averages. I am only including part of the period converter, and with //** I am indicated where I think a person should be able to extract a simple moving average, for instance. If I can do this, then I could write my own file in asci and in a format I could read.
Thanks

I have one other question about the above. As I move through the loop, how can I extract the time for each trade and pass it to a variable?
Thanks
