Hello everyone,
I have 2 fences(1 has 600 gold and the other 800 gold....Ongar and Dar Jee)that once they fence something from me thier money never goes down,,,,is this how its suppossed to work or am i missing something.thanks in advance,
qwert
heres an example: ongar has 600 gold to fence with and he buys 100 gold worth of silver plates and what not...however once done fencing he still has 600 gold......sounds like a bug to me.

No, that's right. You can get insanely rich in this game. The richest I've ever been on one character was well over a million septims... On the other hand, because merchants and fences have a cap on their gold, when you find that enchanted mace that is worth over 5000 septims, you will be only able to sell it for a max (Mercantile Master) of 2200. I limit my money these days by paying taxes for my house (thanks for the idea Acadian), purchasing high-end gear, and then turning around and reselling it for a loss.

Not a bug. It is how the vendors work in this game. They all have a fixed amount of gold that never goes up or down. But they won't ever offer you any more gold for your valuable goods. For instance, if you have an expensive cuirass worth 1500 gold and you try to sell it to a vendor who only has 800 gold, he will never pay more than 800 gold for the cuirass. This goes both for normal vendors and for fences too.

As Big Daddy said, if you train your mercantile skill and get to Expert, you can invest 500 gold to permanently increase the available gold of any merchant. And if you become a Master of Mercantile, all vendors will have 500 gold more to buy your goods, independent of you investing in their shop or not.

If you're on PC, there are some mods that add dynamic economy to the game, including regional prices and/or fluctuating gold.

Actually I think this makes more sense for a fence than it does for regular merchants. It's not the total amount of gold they have, it's the most they'll buy a single item (or bundle of them) for. A fence would know how expensive an item he can handle without drawing attention, so he won't offer any more than his cap. A regular vendor hasn't got that consideration, so maybe they're justing limiting their losses if an item is fake (they can tell if it's stolen!)
