No there isnt. I had taken the first screen shot then clicked into the market, then opened paint and pasted the first screenshot then took the second screen shot. so in all maybe 30 seconds and the traders were already back when I had clicked into the market. This isnt the first time I have had the same thing happen either. Just remembered to get screenshots of it before I clicked to go into the market this time since when i back out it corrects itself. Also I did say it messes up MOST of the time for me not ALL of the time. You also might be using a different browser then me. No clue why the market is messing up could be any number of things
Remember that this is a 10x world so resources build up quickly especially when they are nearly maxed out. at the time I took the screen shots my wood & clay pits were around lvl 28/29 each and iron at 22. and have the 20% bounus thingy on all 3 pists. so was getting close to 20k for wood & clay & a little over 8k for iron and when you have that much coming in an hour you can gain 300+ in just a few seconds
