Right now I've got both my personal and the CH accounts lending with auto-renew on 5 day loans with rates at or above .3%. Seems to be a sweet spot as I never see unfilled offers on either account that I have left on auto.
I do have some on my personal that don't auto as high as 1.15% but, wouldn't recommend setting and forgetting unless you can stand waiting. It only seems to jump up that high about twice a week and even then it's a short window to hit. With ETH, FCT, MAID, RADS and even some SJCX craziness the last couple of weeks there are some moments when the rates skyrocket because someone makes a 'YUGE' margin move and uses all the maker funds to that point. I may put .1 or so at 2% and see if it ever gets taken. hehe
What if any strat are you running now?
