I’m sure the huge spike of 01-03-19 will have a bearing on this as bucket shops brokers all had different levels of trickery; feel sorry for those USA traders that have to use OANDA, holey moley!!
Moving Average is derived from price, if the price is WAY lower, the MA will be lower, best to ignore strict technical analysis about MA until those numbers are in the way past, and out of the calculations, which means anything beyond the 200 period
Google around the internet, there are many many discussions about this, probably even here on BP
Good luck for the next flash crash / black swan / bank intervention / JPY news / etc.
