Brief description

Public funding trade mapping is wrong. There is no maker column in public funding trades.

Steps to reproduce

const BFX = require('bitfinex-api-node');
const bfx = new BFX(
  {
    apiKey: 'xxxxx',
    apiSecret: 'xxxxx',
    ws: {
      autoReconnect: true,
    },
  },
);
const ws = bfx.ws(2, { transform: true });

ws.once('open', () => {
  ws.subscribeTrades(`fUSD`);
  ws.on('trades', console.log);
});

ws.open();

output:

fUSD [
  {
    id: 161367901,
    symbol: 1594289406000,
    mtsCreate: -51.4457011,
    offerID: 0.00020119,
    amount: 3,
    rate: undefined,
    period: undefined,
    maker: undefined
  }
]

Additional Notes:

I had found the same issue in 4.0.2 - 4.0.15 ;(

Hi all, (and @crazyguitar )

I can read comment about 1 year and half ago stating the issue was fixed, but in v5.0.3 the issue is still alive.

Could I please have an estimation of when the fix will be merged and published?

Thank you

Hi @vigan-abd,

I've checked the funding_trade.js file in the bfx-api-node-models package:

1. the const fields mapping respects exactly what the API documentation says;
2. with a console.log in the unserialize method, I saw the data is [ [ 267665633, 1644877838000, -0.1, 0.00002297, 2 ] ] (I would say: ID, MTS_CREATE, AMOUNT, RATE, PERIOD);

I also checked the ws2.js file in this package, and it seems the set of data is not configurable; it is as is when it arrives from the websocket: I'm afraid this needs to be escalated on BitFinex

There is a simple fix: to use PublicTrade instead of FundingTrade, since it is already designed for this, but this will be a breaking change

Public Funding trade has format

 [
    ID,
    MTS,
    AMOUNT,
    RATE,
    PERIOD
  ]

while finding trades

  [
  ID,
  CURRENCY,
  MTS_CREATE,
  OFFER_ID,
  AMOUNT,
  RATE,
  PERIOD,
  MAKER
]

and as far as I found out correctly, _handleTradeMessage receives only data from public trades channel, so FundingTrade should not be used in this case

@vigan-abd wdyt?

fixed in #578

thanks @vitaliystoliarovcc for investigating and providing a fix :)
@iccicci can you confirm that we solved the issue so we can close the ticket?
latest package release that includes the fix is https://www.npmjs.com/package/bitfinex-api-node/v/5.0.4

Sorry for my late reply @vigan-abd , I'm so busy in this period...
Yes, it seems now the fields are correct.
Thank you
