I didn't find my doubt in the documentation, if it's there, point me please.
I'm backtesting a simple strategy, and I've found a big difference between the size in Documents\NinjaTrader 8\db\tick VS Documents\NinjaTrader 8\db\replay
With backtest, it uses db\tick, and when you run market replay uses db\replay.
The size between folder is very big, and the files are differents, db\tick contains .ncd, and db\replays contains .nrd
Could you tell me what is the purpose of each format and why the size is ten times greather? I want to understand how it can affect when I run a backtest.
Thank you.
