I recently posted an update regarding Hertz to Steemit: https://steemit.com/bitshares/@cm-steem/hertz-updates-seeking-price-feed-publishers

I'm seeking new price feed publishers, specifically Bitshares witnesses.

The smartcoin currently requires 7 price feed publishers, and we've got our first - @rolandp, thanks you very much!

I'm hopeful that we can reach 7 publishers soon.

Best regards,
CM.

Hey @Customminer great, sounds interesting, would love to learn a bit more about your thoughts behind the oscillation. Do you have some more info on the (fixed) formula and where can I learn a bit more about the Hertz asset? ... what day would be 0% etc. etc.

Hey,

Within my repo (https://github.com/BTS-CM/scripts) the following files are worth looking at:
* hertz_calculator.xlsx : A spreadsheet for evaluating the effect of different sine wave variables (amplitude, period, etc).
* hertz-verification.py : Used for verifying that the phase offset lines up appropriately.
* hertz-feed.py : What you'd use if you don't use wackou or xeroc's price feed scripts.

Within wackou's repo, here's my code entries: (Note: The pull request #36 needs implemented, or you can change 1/3 to 0.14 if using this script library)
* https://github.com/wackou/bts_tools/blob/master/bts_tools/feeds.py#L275
* https://github.com/wackou/bts_tools/blob/master/bts_tools/feeds.py#L441

And within xeroc's repo: (Issue #25 addresses the inaccurate amplitude comments)
* https://github.com/xeroc/bitshares-pricefeed/blob/master/bitshares_pricefeed/examples/hertz.yaml

Example python code snippet:
hz_reference_timestamp = pendulum.parse(reference_timestamp).timestamp() # Retrieving the Bitshares2.0 genesis block timestamp
hz_period = pendulum.SECONDS_PER_DAY * period_days
hz_phase = pendulum.SECONDS_PER_DAY * phase_days
hz_waveform = math.sin(((((current_timestamp - (hz_reference_timestamp + hz_phase))/hz_period) % 1) * hz_period) * ((2*math.pi)/hz_period)) # Only change for an alternative HERTZ ABA.
hz_value = reference_asset_value + ((amplitude * reference_asset_value) * hz_waveform)
---

So The idea is that with 14% amplitude, and a period of 28 days the value changes 2% every day. We use a phase offset (date/time) to make Wednesday (mid working week) the most important day for Hertz. On Wednesdays, Hertz price feed should be: $1.00 (start), $1.14 (first week passed), $1.00 (2nd week passed), $0.86 (3rd week), $1.00 (final week -> repeat). Check out the spreadsheet calculator to see the value through the month.

I've got some thoughts regarding how the market could potentially react: https://steemit.com/hertz/@cm-steem/what-is-the-hertz-algorithm-based-asset

Regarding oscillation, I believe that we could create phases of buying and sell pressure (through debt destruction as the price feed decreases & price appreciation as it increases), whether this will be realized and become popular is unknown. To make the first Hertz token stable, I significantly reduced the planned amplitude from 50% to 14%. A high amplitude would require high frequency price feed publishing, by decreasing the amplitude I was able to increase the maximum pricefeed lifetime from 220 to 1440 (more acceptable for publishers, hopefully).

Ideally, if this succeeds, we'll see similar algorithm based assets issued which oscillate using different wave equations (cos instead of sin) as well as different hertz parameters (within reason) and backing asset. The reason I created the spreadsheet calculator was for not just my own research but to spread the idea so that others may consider making similar ABAs.

It'd be interesting to create an opposite hertz token with the same parameters except a 2 week phase offset to produce the exact opposite price feed modification/oscillation.

Do you have any specific questions about Hertz?

@roelandp : Could you please begin publishing price feeds for the 'Hertz' asset? I would massively appreciate your support.

Hertz (Hz) is a Algorithm Based Asset (ABA) which is pegged against the USD and modified to oscillate using a sine wave, thus we are able to create potential phases of buying and selling pressure.

Important Smartcoin settings:

• Maintenance collateral ratio (MCR): 175%
• Maximum short squeeze ratio (MSSR): 150%
• Max feed lifetime: 1440
• Delay for forced settlements (minutes): 720
• Percent offset of forced settlements: 1%
• Min number of feeds: 7

Properties of Hertz (Hz):

• Amplitude: 14% (NOT 33% nor 50% - It was changed to 14% for the first HERTZ asset).
• Period: 28 days.
• Daily price feed change: 2% per day.
• Max price feed rate: $1.14
• Min price feed rate: $0.86

Price feed scripts:

• Reference scripts & calculator: https://github.com/BTS-CM/scripts
• Wackou's 'BTS_Tools' (Only use once pull request #36 is merged): https://github.com/wackou/bts_tools/pull/36
• Xeroc's 'Bitshares-PriceFeed': https://github.com/xeroc/bitshares-pricefeed

Many thanks,
CM.

Hey,

I've been working on a Google Assistant for Bitshares recently:
https://steemit.com/bitshares/@cm-steem/beyond-bitshares-google-assistant-development-update-07-jan-2017
https://steemit.com/bitshares/@cm-steem/beyond-bitshares-an-open-source-google-assistant-bot-wip

Anyone interested in Google Assistants? Interested in helping development?

Cheers

bitUSD == USD (Just different ways of referring to it).

Open.USD is real FIAT USD deposited into OpenLedger's bank & issued to the user in return. bitUSD have 2 times the amount of collateral than Open.USD & the collateral is provable on the blockchain.

But how do you do that on the exchange. I do not see any option that allows you to do that anymore

Either at the account overview page or within the exchange section for the specific trading pair you've got open orders on.

You have to cancel open orders individually.
