You mention daily entry and close, but what's the primary timeframe you're basing the trade analysis on?
The trade signal analysis is primarily based on the daily, "regular session" price action for each instrument.
My initial gut reaction to the daily stop losses is that for some instruments I could see you getting stopped out over and over on some of these unless your entries are perfect (e.g. KC, GC). Also, since you're trading a basket of commodities you have to keep in mind that they can still be generally correlated and there may be days where you get killed on every position due to overall moves within the commodity space, e.g. dollar, rates, etc.
Yes, setting daily stop losses will result in some bad runs in each instrument. That is a cost of doing business for using rigid stop loss money management, IMO. But using no stops, discretionary approaches to "close positions on feel", or trailing stops all have their pros and cons. I just personally prefer rigid stop losses. When I'm wrong, I'm wrong and just move on to the next trade.
Yes, there are general correlation issues on some of the pairs. HO is hyper correlated to CL of course, but on CL I do keep a higher stop loss than HO purposely so their fnial trade results are not synchronized all the time. NQ at times can be negatively correlated with GC, but not all the time - look at the past 20 trading sessions in Gold and NQ. GC is much more negatively correlated with the Dollar (DX). NG is like a crazy ex-girlfriend, it just does whatever it wants. KC doesn't seem too correlated to anything in the group. Hogs and Cattle don't share as much correlation as one would think either.
It is futures trading, so no doubt there are days when you get killed on everything at once. I try to measure the ups and downs over weeks and months at a time and look for the profitability / loss curve of the entire basket to smooth out over time.
