Getting market/ticker information

[useo6]

At first: Thank you for providing us such an amazing library. I'm pretty new using this library and I'm using this library for my account created using Crypto-Bridge. Unfortunately I've some questions:

1. How to get a list of all available markets or symbols? I know there's the "BitShares.ticker" function, but it returns information for a specific market (e.g. btc/usd) only.

2. When I call something like "BitShares.ticker('btc', 'dgb')" or "BitShares.ticker('btc', 'ppo')", it throws me the following exception: "Assert Exception: assets[1]: Invalid quote asset symbol: PPO". But the PPO market is available.

I hope anyone has an idea I can retrieve these information. Thank you in advance!

1. Creating a new asset automatically creates markets for all existing assets. Most of them do not have liquidity, but any asset can be traded to any other.
   I did not find an API method for getting all assets. Maybe you need to make a list of assets and make requests for them.

2. Be careful. Crypto-Bridge create assets with the prefix BRIDGE

$ btsdex --asset ppo
Connected to API node: wss://bitshares.openledger.info/ws
Error: Not found asset PPO! Blockchain return PPP

but

$ btsdex --asset bridge.ppo
Connected to API node: wss://bitshares.openledger.info/ws
{
  "id": "1.3.4513",
  "symbol": "BRIDGE.PPO",
  "precision": 7,
  "issuer": "1.2.374566",
  "options": {
    "max_supply": "200000000000000",
    "market_fee_percent": 20,
    "max_market_fee": "400000000000",
    "issuer_permissions": 5,
    "flags": 5,
    "core_exchange_rate": {
      "base": {
        "amount": 100000,
        "asset_id": "1.3.0"
      },
      "quote": {
        "amount": 20000000,
        "asset_id": "1.3.4513"
      }
    },
    "whitelist_authorities": [],
    "blacklist_authorities": [],
    "whitelist_markets": [],
    "blacklist_markets": [],
    "description": "{\"main\":\"PICPOTO\",\"short_name\":\"PPO\",\"market\":\"BRIDGE.BTC\"}",
    "extensions": []
  },
  "dynamic_asset_data_id": "2.3.4513"
}

Try

BitShares.ticker('btc', 'bridge.ppo')

or if you need to use bitcoin from Crypto-Bridge

BitShares.ticker('bridge.btc', 'bridge.ppo')

Regarding the first topic, I decided to decode the Crypto-Bridge ticker. Regarding topic 2... this works like a perfectly.

But I've two more questions:

1. How can I catch the error-event? For example if there's no internet connection, I'm getting the ENOTFOUND-error. How to catch the error?

2. Can I disable the ws-output? When I subscribe it outputs "WebSocket status: open". Is there any way to disable this output?

[scientistnik]

For catch error, try:

process.on('unhandledRejection', (reason, p) => {
  console.error(`Unhandled Rejection at: ${p} reason: ${reason}`);
});

Currently you can not disable the ws-output.

Thank you scientistnik. This helped me a lot! One last question... do you know how I can get a list of trades, deposits or withdrawals I've done in the past?

[scientistnik]

Get history account objects:

await BitShares.history.get_account_history(<account_id>, "1.11.0", 100, "1.11.0") // last 100 operations

[useo6]

Ah, I see. Thank you scientistnik. I've two last questions... how to generate a new address for an asset and how to withdraw from an asset?

[scientistnik]

What you mean "new address"?

[useo6]

I mean on CryptoBridge I can click on "Get New Address" and I'm getting a new deposit address for the corresponding asset.

You need to ask this from CryptoBridge)
