First let me say this… I’ve been on NinjaTrader long before the NinjaTrader 7 version came out, so this is my personal opinion and experience of using NinjaTrade 7 and NinjaTrader 8.
Even though it was a great product when it came out I had some serious issues with version 7 when it came to using Order Flow with DELTA. NinjaTrader 7 only operates on one single core (regardless of what chip-set you have Intel or AMD) and this slows down the processing (calculating the DELTA between bars). Next, you will notice the system will hang (get slow) when new data is being added... my advice is that you DO NOT use WORKSPACES in NinjaTrader 7, this will clog (choke) the system resources and you will have multiple crashes and system freezes.
DO NOT use any WORKSPACES on NinjaTrader 7 or 8 (They are cumulative and whatever is in them will keep adding data to the file until it crashes). Trust me on this I've been using NinjaTrader for several years. DELETE ALL WORKSPACES in NINJATRADER 7 and 8, you should ONLY use templates to load your charts... yes, it is a bit more work, but your system will RUN EXCELLENT (especially if you do this listed below):
Next, you MUST do two Things in NinjaTrader daily for optimal performance:

1.) Clear the database - (First close the connection) then Go to TOOLS then select DATABASE MANAGEMENT:
https://gyazo.com/45039b35bb5834e435f5be753ac9492a these must be deleted each day (or each time you restart NinjaTrader).
2.) Clear the DB files - Go to your windows documents folder: Select NinjaTrader 8 and open the file. Next, find the folder called: DB once you have selected this open it and it will look like this: https://gyazo.com/f62d16bde196354ff803d42869d8e8fc Next, select the following folders: TICK, MINUTE, DAY, and CACHE... these must be deleted each day (or each time you restart NinjaTrader)
Now I'm going to tell you why the professional traders do not use NinjaTrader 7 or (the FREE version or the LEASED version of NinjaTrader 8. If you got to this page: https://ninjatrader.com/BuyPlatform you will notice there are three different versions of NinjaTrader 8. Notice on the one that says OWN (this package is the only one that has the built-in Order Flow included: https://ninjatrader.com/Order-Flow this is the only version the Professionals will use who are trading with DELTA or other Order flow tools. The reason is because this is the only version of NinjaTrader that has DELTA built into the program and is now NATIVE to the application. This version runs completely different than any of the others in the past. It's extremely fast when calculating the DELTA and the system NEVER CRASHES or HANGS-UP on slow data.
Bottom Line: IF you want NinjaTrader to run optimally use the steps above, if you want to use the Order Flow tools optimally use the Lifetime License version on NinjaTrader with the built-in DELTA that is native and you will experience NinjaTrader at its best. I can tell you from years of experience with NinjaTrader, the new Order Flow version is easier than any software trading platform on the market and has ZERO headaches when it comes to professional trading.
Sincere wishes for a good life
and (always!)... higher profit$,
