hi
i have a long historical data of fdax.i used kintik and other sources and corrected and amended the data for many dates.my question is if i now connect to kintetik or zenfire,will my amended historical data will be overwritten by kinetik or zenfire.if all my amendments will be overwritten ,then how can i avoid that.
pls advise

easyfying, if you reload historical data completely an overwrite could be the case - however NinjaTrader would only load data in those cases here -

What you can do is update your charts with a low lookback setting only and then disable historical data access for the connection > then reconnect for collecting the realtime data.
