I found a strange behaviour with the FXCM 64bit Plugin. When I start Zorro (2.70) for trading, I get an NaD message in the LookBack run.
This behaviour I recognize especially for daily bars. In my example with asset GER30, I have historical data in the history folder available until 2008.
With the 32bit plugin I have no issue.
With the 64bit plugin:


AL09-G1-R2-1440-V1 start
Login 0 FXCM.. at UTC 01-21 19:24.
Error 047: GER30 1899-12-30 2026-01-21: 0 bars, 0 skipped, 500 needed)
Read AL09-G1-R2-1440-V1.fac
Read AL09-G1-R2-1440-V1.par......

Trade: AL09-G1-R2-1440-V1 2026-01-21
Assets AssetsStandard.csv
Lookback 500 bars, (NaD)..(NaD).

Also for other assets I can repeat this behaviour. It seems that the plugin does not collect historical data from the history folder during the LookBack period?

PRELOAD Flag is set. When I remove the PRELOAD Flag, for the shorter time frames the Broker data are loaded, but for the longer I get this error. Strange?

NaD means Not a Date, maybe it's something with the start and end date? 1899 12 30 is also an invalid date.

Start Date is 2011 and End Date 2026. Some assets work in this strategy and some not. BarPeriod=1440.
I checked the history folder, but these assets (.t6 files) are working for 32bit Zorro. Therefore the .t6 files cannot be corrupt. It seems I have an issue witch the Zorro64 and the Plugin.
But generally the most strategies under Zorro64 and FXCM-64 Plugin running, thats what is so strange.
I checked also the manual regarding error 47 and the dependency to LookBack and insufficient historical data...

If it only happens with some scripts, but not with others: Do they have something in common? Maybe some setting or a broker command?
