Thank you all for your suggestions. ZN, ZB, 6E, EuroStoxx are all suggestions that I was looking for. Now, I need to SIM each product and figure out what works for my style. I am not adverse to CL and GC, I just have to adjust my style if I trade them. If anyone trades ES as a primary, I would like to know from other traders what they personally would trade to complement their ES trading. Their personal choices and why. Just curious. Thanks in advance for anyone participating. It has been a huge help.

Although multiple markets do help with this, consider also sometimes market conditions are just not ideal for our strategy and it is better to sit out and wait patiently, rather than always be putting on risk. This is a difficult skill to learn.

There are two sides: One, when you try and capitalize all the time (over trading) and at the same time you just sit and look "forever" without the ability to capitalize on anything thinking you will get a "feel" for the markets. These are two symptoms of traders who do not realize the strength or weakness of their systems and its application.

There is a substantial risk of loss in futures trading. Past performance is not indicative of future results.

Maybe you are starting off on the wrong foot, looking for another market that suits your style or strategy. I would look at any new market from a totally blank slate and try to learn what types of strategies work best in that market. There are plenty of resources out there on the web and on youtube that can get you started.
