Hi Petko,

Thanks for your reply well, these days I discovered that the historical data must match the broker both in Time and specifications for the particular currency pair.

I am reloading the data for 4 brokers at the moment which are IC Markets, JFD, Dukascopy and Blueberry Markets I want to test them all to see what outputs they will give me. Do you think this is a good idea?

I had two question about the times in GMT which I posted in another topic,

-Do we need to constantly update this data periodically (Say every 6 months or so)?

-Do we need to update the data for the broker when winter time comes due to the daylight savings?

Thanks again
