Yes, you are right, the Feeds were not given correctly, that's why we need to create a committee, each member of which will publish Feeds for a smart asset. Also each member of the committee will confirm (if desired) the change in the smart asset with the help of a multi-signature. Otherwise, we will be subject to manipulation in the future ....

7 members of the committee in the first stage with a vote power of 15% and a threshold of 40%.
15 members of the committee in the second stage with a 10% voting power and a threshold of 60%

Аккаунт zapata42-witness  was added to the committee, since he already publishes Ауувы for a smart asset AMAZONCOM

Please share your opinion about this idea

unfortunately, practice showed that when smart assets are managed by one or two accounts, and quotes also gives one account - this leads to manipulation with both Feeds and with the asset itself. This was done with the smart assets of FACEBOOKCOM and APPLECOM

In order to get fully reliable smart assets - we create our own committee of seven accounts (in the future it is desirable to expand it to 15 accounts), which will independently publish quotations and confirm any change in the smart asset using a multi-signature account

Become a member of the committee Smart Assets Derivatives for Nasdaq shares.
We create the comet as a committee that controls the bit of Asset, bitUSD, bitCNY ..., which will manage smart  Assets for Nasdaq shares, as well as the account, issuer of the derivative.
The account will be assigned multi-signatures, so that any action with smart assets will require the approval of the committee.
As a reward, the members of the committee will be divided by the profit from the volume of trades in Derivatives for the shares of Nasdaq.
Initially, I propose to gather a committee with 7 participants, in which there will be 3 votes to make a decision.
Initially, there will be one AMAZONCOM smart asset in the management, because Two independent accounts are publish Feeds to this smart asset.

Commission for transactions with a smart asset AMAZONCOM is 0.2%. It is she who will be divided among the members of the committee.

Obligations of the participant:
Publish Feeds for a smart asset AMAZONCOM (please., Learn how to do it yourself)
Confirm transactions (once a month to distribute profits between members of the committee)

Become a member of the committee, take part in the development of Bitshares

If you want to become a member of the committee, specify your account here and you will be added to publish the quotations and receive a share in the account of the issuer with a multi-signature

Further continuation of the topic will be here - https://bitsharestalk.org/index.php?topic=26927.0

I have updated xeroc's bitshares-pricefeed to be able to publish your assets (see this issue).

It currently support IEX, AlphaVantage, RobinHood and Google Finance as stock price sources.

When I try to publish using IEX for Stock/USD price and Bitshares DEX current feed for USD/BTS, I have a spread with your prices (see column blockchain):

Any idea why there is such a spread? As JohnR asked, could you give us some insights on your pricing mechanism?

I can setup a price feed if you white-list zapata42-witness.

The code is under MIT license so any one can use it to setup their feed, I hope this will help decentralization.

account zapata42-witness is added to the whitelist for publication of feeds by smart asset AMAZONCOM
As soon as you manage to publish the feeds for smart asset AMAZONCOM, I will add you to the white list of all smart assets
Please try...

I have the price of the stock in dollars and multiply it by the exchange rate bts/usd.
I take the course of bts from the purse of the bitshares. Those. from a usd / bts pair on the bitshares exchange.

Any idea why there is such a spread? As JohnR asked, could you give us some insights on your pricing mechanism?

I can setup a price feed if you white-list zapata42-witness.

The code is under MIT license so any one can use it to setup their feed, I hope this will help decentralization.

All smart assets derivatives for shares are launched without using donations from the community. Donations are just an extra possibility. Since there are several thousand shares in the stock market, derivatives will not be launched for all shares.

(If you want to publish feeds for smart assets - Nasdaq and NYSE shares, please specify the name of the account and you will be added to the white list for feeds.)

First of all - I think this is a great project that is not getting nearly the attention it deserves.

I would love to help arrange more price feeds for greater stability of these coins.

Is this how you've done all the other tokens you listed (with donations)?  I have associates very interested in working with you in a business capacity on this project.

At this stage of development, the project lacks only the diversification in the publication of feeds. Feeds publish only two accounts. Ideally, if the witnesses start publishing quotes.

Also, you can take part in the launch of a new derivative for the share
The cost of starting a single derivative is about 3500BTS
This includes:
Creating a Smart Asset
Dispatch smartasset 100 000 accounts of 0.00001 coins
Publication  of Feeds
Liquidity support (at present, liquidity in derivatives is temporarily not supported due to technical difficulties)
If you donate 3500 BTS, the derivative will be launched for the share that you select.
If the amount of the donation is less then the next will be the derivative for Deutsche Bank shares

If you want to support the launch of the derivative for shares - transfer BTS to "derivatives-dex" account

I have seen these on DEX and think it is a great project.  It is great to see a financial institution mixed in (maybe AliBaba has a financial arm but I did not research that).  How can we support this project?  How do you calculate price feeds?

This is an interesting idea.  I support it.  Is this the first smartcoin tracking a financial institution's equity price?

At the moment on the Bitshares Exchange traded 15 smart assets Derivatives for the shares of Nasdaq and NYSE

VISACOM
BOEINGCOM
MCDONALDSCOM
MICROSOFTCOM
STARBUCKSCOM

The feeds for smart assets - Nasdaq and NYSE shares publish two account:
nasdaq-bts
nasdaq-fb
Feeds publish every 15 minutes

The account escrow-bts sends out to 0,00001 coins of each smart asset for the promotion of derivatives trading
