# Hertz 71% activated! 2 more witnesses to go!

I've been posting regular updates regarding the Hertz Algorithm Based Asset & I'm happy to announce we've hit 71% activation thanks to our 4th and 5th price feed publishers!

So a massive shout out to [sc-ol](https://steemit.com/bitshares/@sc-steemit/joining-in-as-bitshares-witness) and [verbaltech2](https://bitsharestalk.org/index.php/topic,23902.0.html), today they both began publishing price feeds for Hertz, bringing us closer to an active Hertz market.

You can see the [current price feed publishers on CryptoFresh](http://cryptofresh.com/a/HERTZ) at the bottom of the page.

Don't be alarmed by the difference in price feeds being reported, as time progresses and we attract the interest of more witnesses we'll iron out the issues.

# Wackou price feed update reminder!

Wackou recently [merged pull request #36 into the master branch](https://github.com/wackou/bts_tools/pull/36#event-1420892174) of the BTS Tools repo. If you're using BTS Tools to publish price feeds, please update to the latest version.

# New Hertz developments?

## Reference Hertz price feed HUG API

No surprise here, I've continued updating the [Bitshares HUG REST API](https://github.com/BTS-CM/Bitshares-HUG-REST-API), this time adding extra unofficial reference data, updating the hertz formula in line with the reference hertz price feed script & correctly handling private price feed publishers listing hertz value of 0 (no price feeds yet, caused a crash in the API).

## [Reference Hertz price feed script]() updates

The [reference Hertz price feed script]() was updated to clean up the code & comments and fixes a couple glitches reported by [sc-ol](https://steemit.com/bitshares/@sc-steemit/joining-in-as-bitshares-witness).

## Committee request to increase max price feed publishers from 10 to 25

This was an [issue observed & reported](https://github.com/bitshares/bitshares-ui/issues/1025) last week, preventing the addition of more than 10 private price feed publishers. This will hopefully be increased by the Bitshares committee within the next week or two.

# Are you a Bitshares witness?

Please begin publishing price feeds for the [HERTZ algorithm based asset](http://open-explorer.io/#/assets/HERTZ).

I have sent private messages to most active witnesses via Bitsharestalk, or I have posted in your Bitsharestalk witness threads.

### Example Python 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)
```
