bitmexr 0.3.0 - Whats new?

The latest CRAN release of bitmexr supports placing, editing and cancelling orders on the BitMEX exchange. These actions are supported by the following functions:

See the package documentation or the BitMEX website for details on what arguments can be used with each function.

Practice on the Testnet

BitMEX has a fully functional Testnet exchange that lets you use a “practice” version of the live exchange. This is great for trying out a new trading idea or using trying these functions out in a risk free environment that is identical to the real thing. Every function in bitmexr has a Testnet equivalent - simply use the “tn_” prefix to access the Testnet version of the function. For example:


place_order(symbol = "XBTUSD", price = 5000, orderQty = 100)

Will place an order on the live exchange, whereas:


tn_place_order(symbol = "XBTUSD", price = 5000, orderQty = 100)

Will place the order on the Testnet exchange.

Authentication needed!

In order to use these new functions you must first obtain an API key and secret for the account you wish to use with bitmexr. With API key and secret in hand, you can add these to your ~/.Renviron file using:


bitmex_apikey = "api key"
bitmex_apisecret = "api secret"

for the live exchange or


testnet_bitmex_apikey = "testnet api key"
testnet_bitmex_apisecret = "tetsnet api secret"

for the Testnet exchange.

See the Authentication vignette for more details.

Extras

Speed boost

With authentication set up, map_trades() and map_bucket_trades() get a speed boost due to increased API limit when using authentication. Simply set use_auth = TRUE to get these functions running at 60 API call per minute .

Additional API endpoints

For additional API endpoints that don’t have a dedicated API wrapper in bitmexr, it is possible use either:

and

These functions just need the path to the API endpoint and a named list of valid parameters for that endpoint. For example, you could use:


chat <- get_bitmex(path = "/chat", 
                   args = list(channelID = 1, 
                              reverse = "true"))

To get the latest English trollbox chat data (not sure why anyone would want this, but it is possible!).

What next?
