Steem Dollars discount - why is it always below open market price?

The current liquidity provider reward does not seem to have any feedback to reward accuracy. It only rewards the amounts traded, which in the fullness of time might end up making the Steem dollar match a dollar, but I dont see any guarantee of this. Actually, the way I see it now, it appears to guarantee that the Steem dollar will trade below the implied price, or at least have a rather large spread.

The price of the Steem Dollar is set by the internal market of Steem dollar vs Steem. At any given time this is 10%+ discounted to the implied bittrex price. Usually the orderbook is pretty thin and a few hundred dollars can move the price by 50 cents or even a dollar. Occasionally, a large bid (or ask) appears that is almost always matched in a minute, so the liquidity points are earned by the "liquidity" provider. Now it is true that during this minute another party could sell into the bid so a bit of care needs to be take to put the bid below market price, that way even if it is sold into, it is no big deal.

$10 $3.00
$10 $2.90
$10 $2.80
...

then: $8000 $3.01 for 61 seconds to be filled right away earning the liquidity points according to the current system. and back to the thin orderbook.

Since there is risk of being filled for the 60 seconds, it means the current incentive is to put the bid as much below market price as possible (and asks as high above market price as possible). Now for the amount of incentives being paid, I think it is reasonable for the liquidity reward to incorporate some semblance of matching the $1 price. If it did, then people could convert to and from Steem dollars at $1 instead of at a discount.

This would require a change to the liquidity provider points to include distance from the current implied market price, which means bittrex as that is the only external price point for now. The good news is that steem has built in the ability for getting external price feed info so this should be possible to do.

I therefore suggest that distance from the price feed be a factor in the liquidity reward. Another factor that should be incorporated is the length of time a bid (or ask) is on the books. Right now it is a minimum of 60 seconds, so of course it is there for 61 seconds. While that is better than 1 second, it really isnt long enough for the community to benefit from the large liquidity that is available.

Adding the above common sense factors to the liquidity awards will reduce the domination effect possible by abit's account. If abit was providing massive liquidity at the $1 price, then I wouldnt be complaining. But the reality is that this is not being done at this point so it seems the point system needs to be tweaked.

I will be making a liquidity bot that aims to be as accurate as possible and as long as it isnt overpowered by higher capitalized bots, I will do my best to keep the peg. Based on the large upvote of my intro post, I have a bit of capital to use for this and I intend to use as much of the upvote rewards as possible for market making liquidity. Please dont get me wrong, I am very pleased that the numerical precision advantage that a large account had is now neutralized, which is fast progress to a level playing field.
