New data is indeed available by FXCM, and the problem only appeared in the data files downloaded 2011 or earlier with their old API. We'll download and replace the files in the next days. As to my knowledge, the issue has no practical effect on backtesting normal systems, so it is not a matter of urgency.
Probably the impact to 1h and 4h timeframes is negligible. But it is paramount on 1m and 5m. Don't know how many people look for market inefficiencies on such low timeframe, but I was guilty doing that in the past, and intend in the future.
Please just leave a note when updated history files are in place, so we can download and replace the old ones. Thanks!
