* port orderbook binance management from draft singular asset (spot) processing add additional updates to buffer management * integrate port * shifted burden of proof to exchange and remove repairing techniques that obfuscate issues and could caause artifacts * WIP * Update exchanges, update tests, update configuration so we can default off on buffer util. * Add buffer enabled switching to all exchanges and some that are missing, default to off. * lbtc set not aggregate books * Addr linter issues * EOD wip * optimization and bug fix pass * clean before test and benchmarking * add testing/benchmarks to sorting/reversing functions, dropped pointer to slice as we aren't changing slice len or cap * Add tests and removed ptr for main book as we just ammend amount * addr exchange test issues * ci issues * addr glorious issues * Addr MCB nits, fixed funding rate book for bitfinex and fixed potential panic on nil book return * addr linter issues * updated mistakes * Fix more tests * revert bypass * Addr mcb nits * fix zero price bug caused by exchange. Filted out bid result rather then unsubscribing. Updated orderbook to L2 so there is no aggregation. * Allow for zero bid and ask books to be loaded and warn if found. * remove authentication subscription conflicts as they do not have a channel ID return * WIP - Batching outbound requests for kraken as they do not give you the partial if you subscribe to do many things. * finalised outbound request for kraken * filter zero value due to invalid returned data from exchange, add in max subscription amount and increased outbound batch limit * expand to max allowed book length & fix issue where they were sending a zero length ask side when we sent a depth of zero * Updated function comments and added in more realistic book sizing for sort cases * change map ordering * amalgamate maps in buffer * Rm ln * fix kraken linter issues * add in buffer initialisation * increase timout by 30seconds * Coinbene: Add websocket orderbook length check. * Engine: Improve switch statement for orderbook summary dissplay. * Binance: Added tests, remove deadlock * Exchanges: Change orderbook field -> IsFundingRate * Orderbook Buffer: Added method to orderbookHolder * Kraken: removed superfluous integer for sleep * Bitmex: fixed error return * cmd/gctcli: force 8 decimal place usage for orderbook streaming * Kraken: Add checksum and fix bug where we were dropping returned data which was causing artifacts * Kraken: As per orderbook documentation added in maxdepth field to update to filter depth that goes beyond current scope * Bitfinex: Tracking down bug on margin-funding, added sequence and checksum validation websocket config on connect (WIP) * Bitfinex: Complete implementation of checksum * Bitfinex: Fix funding book insertion and checksum - Dropped updates and deleting items not on book are continuously occuring from stream * Bitfinex: Fix linter issues * Bitfinex: Fix even more linter issues. * Bitmex: Populate orderbook base identification fields to be passed back when error occurrs * OkGroup: Populate orderbook base identification fields to be passed back when error occurrs * BTSE: Change string check to 'connect success' to capture multiple user successful strings * Bitfinex: Updated handling of funding tickers * Bitfinex: Fix undocumented alignment bug for funding rates * Bitfinex: Updated error return with more information * Bitfinex: Change REST fetching to Raw book to keep it in line with websocket implementation. Fix woopsy. * Localbitcoins: Had to impose a rate limiter to stop errors, fixed return for easier error identification. * Exchanges: Update failing tests * LocalBitcoins: Addr nit and bumped time by 1 second for fetching books * Kraken: Dynamically scale precision based on str return for checksum calculations * Kraken: Add pair and asset type to validateCRC32 error reponse * BTSE: Filter out zero amount orderbook price levels in websocket return * Exchanges: Update orderbook functions to return orderbook base to differentiate errors. * BTSE: Fix spelling * Bitmex: Fix error return string * BTSE: Add orderbook filtering function * Coinbene: Change wording * BTSE: Add test for filtering * Binance: Addr nits, added in variables for buffers and worker amounts and fixed error log messages * GolangCI: Remove excess 0 * Binance: Reduces double ups on asset and pair in errors * Binance: Fix error checking

BTCMarkets Exchange
Current Features
- REST Support
- Websocket Support
How to enable
-
Individual package example below:
// Exchanges will be abstracted out in further updates and examples will be
// supplied then
How to do REST public/private calls
- If enabled via "configuration".json file the exchange will be added to the
IBotExchange array in the
go var bot Botand you will only be able to use the wrapper interface functions for accessing exchange data. View routines.go for an example of integration usage with GoCryptoTrader. Rudimentary example below:
main.go
var b exchange.IBotExchange
for i := range bot.Exchanges {
if bot.Exchanges[i].GetName() == "BTSE" {
b = bot.Exchanges[i]
}
}
// Public calls - wrapper functions
// Fetches current ticker information
tick, err := b.FetchTicker()
if err != nil {
// Handle error
}
// Fetches current orderbook information
ob, err := b.FetchOrderbook()
if err != nil {
// Handle error
}
// Private calls - wrapper functions - make sure your APIKEY and APISECRET are
// set and AuthenticatedAPISupport is set to true
// Fetches current account information
accountInfo, err := b.GetAccountInfo()
if err != nil {
// Handle error
}
- If enabled via individually importing package, rudimentary example below:
// Public calls
// Fetches current ticker information
ticker, err := b.GetTicker()
if err != nil {
// Handle error
}
// Fetches current orderbook information
ob, err := b.GetOrderBook()
if err != nil {
// Handle error
}
// Private calls - make sure your APIKEY and APISECRET are set and
// AuthenticatedAPISupport is set to true
// GetUserInfo returns account info
accountInfo, err := b.GetUserInfo(...)
if err != nil {
// Handle error
}
// Submits an order and the exchange and returns its tradeID
tradeID, err := b.Trade(...)
if err != nil {
// Handle error
}
