I post this in case anyone else is as frustrated as I was trying to load futures data for GC 12-18 in NinjaTrader 7.
I kept receiving errors regarding the lack of historical data. The NinjaTrader forums were useless. In the end, I found the fix comparing symbols in the default instrument data versus symbols used by Kinetic.
Changes made:
Tools/Instrument Manager
Find the Name (GC)
Double-Click or Click the Edit button
Go to the Misc. Tab
Under Symbol Map, Find Kinetick
Change QGC to QMF
It then works. QGC is for pairs and should include another letter (e.g. QGCI) and this is for pairs versus strict Sweet Light Crude Oil. From the Kinetick database:
QGCIU18 GC #6 FUEL OIL 3% (PLATTS) VS BRENT CRCK SEPTEMBER 2018
QGCUZ18: GC #6 FUEL OIL 3% VS EURO 3.5% FUEL OIL DECEMBER 2018
Versus:
QMFZ18 GC #6 FUEL OIL 3% SULFUR DECEMBER 2018
Hope this helps someone else out. Keep in mind that if you reset the Instrument Database, it will likely revert to QGC unless NinjaTrader has updated it on their side.
