@Gentso- do you believe there is any such thing as a perfectly accurate price? What's the spread at btc38? 1%? 0.5%? Which price is the price you think is "correct?" The bid or ask? The price of the last trade? I think you'll agree with me that none of those are quite right; you'd almost always be more interested in something between the bid and ask. So what do you pick? The average? A recent moving average of market prices? Those sound better, but they're still only estimates. Maybe I'm being long-winded, but I'm trying to make the point that there isn't ever 1 price and the best you can ever do is estimate it. So adding in 0.2% noise will still give an accurate price feed, especially if everybody is doing it and all the noise averages out.

@Xeroc, I haven't actually designed a manipulation algorithm to exploit feed price prediction, but isn't it obvious that a noisy feed would be better than a predictable one? I'm working from this principle: if I can execute trades on btc38 and predict exactly what that will do to the price feed, then I can make money moving the price feed around. Probably a fraction of a percent per trade, but the fact is I'll be taking money from the system without providing any benefit. Doesn't that sound like something we should try to prevent?

maybe we can find a compromise and have a randomness in-line with the lowest spread of your exchanges .. if btc38 says 1% you may add randomness with a spread of less than 1% with confidence >90% or so ..

So now onto the main question. I need delegates that (upon receiving my stake), will reward me with part of their profits.

There aren't any I think.

Last week I'm quite sure I sent a deposit of 13,396 to Bter. I have screenshots of my client with all the "btercom" transactions filtered out, and my deposit shows up in that list.

However, Bter tech support tells me it's not showing up in the Bter wallet! Does anybody have any idea what this could mean? The txid prefix is 142a3e31, and you can see it's a transaction in this block: http://bitsharesblocks.com/blocks/block?id=1575565

Is there anywhere my deposit could have gone except to Bter? Does Bter need to re-scan? This happened around the time 0.5.0 came out; maybe the deposit came in while they were updating and somehow didn't get scanned properly by their wallet?

Is there a way they could scan my transaction in particular to verify that it's to them?

Please verify from your transaction history that the receiver is indeed "btercom"

I am confident that bter.com already knows how to handle theses issues.
They have two options:

- rescan 1575565 .. which contains the transaction
- wallet_verify_titan_deposit 142a3e31

the first one should make the transaction appear while the second one would tell them if the transactions is redeemable by them (read: you indeed sent to btercom).

From the observerspoint of view there is no way to figure out where the tx went to and who can redeem the funds. but btercom should be able to check if THEY can ..

I run the market maker bot on bter to make money. It provides liquidity but it trades on a spread against bitstamp's BTC price. It has the side effect of also supporting the peg. This isn't false volume in IMHO as even non Bitshares supporters would do this to make money.

Changes I just submitted:

1) config.json now supports new parameters MinBal_Quote, MinOrder, and Base.

2) Logic changed to use all funds in your account up to the MaxOrder parameter with an order no smaller than MinOrder that also does not put the account below MinBal_Quote.

For example if you set MinBal_Quote to 1 and MinOrder to 0.5 and MaxOrder to 5 it would use all the funds in both bitUSD and BTC to submit orders of value 0.5 BTC or greater up to 5 BTC that still leaves 1 BTC of value in both BTC and bitUSD.
