[Nubot Gateway] Poloniex @zoro (sell offset:0.25% , buy offset:5% ) - stand by

[masterOfDisaster]

@zoro, please check the price feed yout NuBot uses.
I haven’t configured one manually, but that’s not good at the moment.
It chooses bitchain.info as default, but that price is far off:

22:42:11.789 [priceTriggerTask] INFO  - New price computed [Sat May 28 22:42:11 UTC 2016,blockchain,BTC,507.0,USD,0.0019929,0.00189329,] [com.nubits.nubot.tasks.PriceMonitorTriggerTask:483]

https://bfxdata.com/orderbooks/btcusd is at 533 at the moment,
https://bitstamp.net at 524
BTC/USDT at Poloniex 519
etc.

507 is way too cheap!
We need to find a more reliable data feed.

edit:
I’m trying

  "mainfeed":"bitstamp",
  "backupfeeds": ["bitcoinaverage", "kraken"],

All three have a BTC/USD rate that is at level or slightly above Poloniex.
We’ll be better off than with blockchain.info - at least for now.

My nubot uses bitfinex. Which is currently the biggest (in volume) btc/usd exchange

Don’t all pools and gateways on the same exchange need to change feed at the same time to avoid wall collision?

[masterOfDisaster]

With a tight spread they should…

@zoro, did you check your NuBot recently?
Mine reported API errors and I had to restart it.

Maybe you want to put less funds on the order book - just in case you have a NuBot malfunction during heavy swings.
What about this suggestion?

  "bookBuywall": 750.0,
  "bookBuyOffset": 0.05,
  "bookBuyInterval": 0.01,
  "bookBuyMaxVolumeCumulative" : 2000,
  "bookBuyType": "lin",
  "bookBuySteepness": "low"

This will provide $2,000 on buyside at an offset that is below mine (which is currently at 7.5% with 1.5% increase each order, while yours are at 5%, 6%, 7%)

[zoro]

It is fine ATM. But i wil follow your suggestion, thanks

You are slowly losing BTC.
Have you considered increasing the buyside offset?
How’s your current sellside offset?

The high buyside offset derailed the NBT/BTC pair to some degree. Even with 0% sellside offset, you’d be quite far from being on top of the sell side order book.

USD rate of the NBT/BTC for the 2,994 NBT sell order: 1/0.169436 = 590

Current BTCUSD rate (bitfinex): 575

With 0% sellside offset, you’d be 2.5% more expensive than the $3k order - no chance of selling NBT even at 0% offset.
It looks like the buyside offset of 5% moved the mid price and created a “virtual” USD price in the NBT/BTC pair of $590.

“bookSellOffset”: 0.0045
"bookBuyOffset": 0.035

i can decrease sell side at 0.0025
and increase buy at 0.05 ?

[masterOfDisaster]

If we want to learn from the situation it might be better not to change the settings/offsets too often.
I don’t know. I find 3.5% buyside offset rather small for the current situation (and would indeed prefer 5%).

But let’s wait for what others, e.g. @mhps say.

[mhps]

spread 1/5 of the fund at 3.5, 2/5 4, 2/5 at 5

[zoro]

Do it!
