Differences between oanda and metatrader data about oanda-api-v20

[hootnot]

hi @vtandrea , during the transition from v1 to v20 I saw differences in streamingquotes. too. I asked them about this and it had to do with aggregating prices over 0.25 of a second in v20 vs. no aggregating in v1. V20 gives a lot less ticks compared to v1.
You talk historical data here. I would say that it should be equal. The impression I have from it is that there are different datasources. Questions that rise: which one is right ? or are both wrong?

Since this is not a question regarding my code, you really should drop it at OANDA. If they gave you the answer, pls. post it here too
