The data is bid-ask(ticks) and stems from a retail fx broker(gain capital) ,but the frequency is lower than Olsen data's of course and there are a few bad ticks ,therefore Quoteif you are going to create a program that compresses the tick data into a higher time frame you would want to make sure that you have a filter in your code that takes these bad ticks out.
