Important
Please note that Portara does not get involved in data matching or data comparison for any reason whatsoever to any other data suppliers. This includes online charts analytics websites brokers and backtesters, whether that is via free online data, paid services or other.
It is important to realize that ALL data will vary to some degree between suppliers for very many reasons. When considering backadjusted continuous data, this can be pronounced given the cumulative effects during the backadjust calculations.
If you are a veteran trader then this will undoubtedly be understood, but if you are new to trading, a student or possibly researcher new to futures data and its many nuances, then please make sure you fully understand this policy.
