* 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

Current Features for orderbook
-
This package facilitates orderbook generation.
-
Attaches methods to an orderbook
- To Return total Bids
- To Return total Asks
- Update orderbooks
-
Gets a loaded orderbook by exchange, asset type and currency pair.
-
This package is primarily used in conjunction with but not limited to the exchange interface system set by exchange wrapper orderbook functions in "exchange"_wrapper.go.
Examples below:
ob, err := yobitExchange.FetchOrderbook()
if err != nil {
// Handle error
}
// Find total asks which also returns total orderbook value
totalAsks, totalOrderbookVal := ob.CalculateTotalAsks()
- or if you have a routine setting an exchange orderbook you can access it via the package itself.
ob, err := orderbook.Get(...)
if err != nil {
// Handle error
}
