to perform backtesting with Range bar Data Series and Historical fill processing High and 1 tick value.
Everything works fine so far.
I want to add and purchase more historical tick data that is older than 10 years.
However this is only available in Tick Format (Second Granularity) yyyyMMdd HHmmss;price;volume .
Can I expect the same accurate range bars and backtesting results in NT8 with Tick Format (Second Granularity) data for the time period before 2011 or are there any disadvantages?
