big gaps in EURUSD history chart

 

I am looking at EURUSD chart. There are big gaps of uncharted data. For example: There is data for 10th of Dec 2010. Next block is for 17th of Dec.

This is just one example.. I have already found a few cases of missing history data.

How can construction and optimization of models be done with faulty data?

Does anyone know where did 7 days of data go?

Thanks
