He's (Kaigee) has been busy lately, so he hasn't been able to update the bond charts as much as he'd like, but the charts give you an idea of when the bonds are adjusing, how much they'll adjust, and the profit you make - takes the guess work out of it for you & easy $$. Just make sure you know HOW starbonds adjust before you jump in buying them.
If you're not playing openers each week, you should be. Sure, it's tricky to try and guess how to hold them, but you have a 50/50 chance of picking it right, and playing openers is probably one of the fastest ways to build your port. You can either short them, or long them, but play them. With a port of $100M, there's no reason you shouldn't be taking advantage of this. Sure, you can lose $$ if you pick'em wrong (which I've done plenty of times - I shorted Spiderman 2!!) but playing openers is still one of the most fun aspects of HSX for me.
Other than that, sounds like you're doing well with your current strategies, so continued good luck!!!
