Placing and managing orders with bitmexr


bitmexr now supports placing, editing and cancelling orders on both the testnet API and live API provided by BitMEX. This vignette outlines how you can use place_order(), edit_order() and cancel_order() to manage your BitMEX trading directly from R! For more information about the API please visit (

The following examples will use the tn_* varients of the managing trades functions (tn_place_order(), tn_edit_order() and tn_cancel_order()) to access the testnet API. These functions will work in exactly the same way when using the live API (without the tn_ prefix).

Placing orders

Use the following to place an order on the exchange

tn_place_order(symbol = "XBTUSD", 
               orderQty = 10, 
               price = 5000)

If price is not specified, a market order will be used.

tn_place_order(symbol = "XBTUSD", 
               orderQty = 10)

You can specific side = Sell or use a negative orderQty to initiate a sell order.

tn_place_order(symbol = "XBTUSD", 
               orderQty = -10, 
               price = 10000)

Use ?tn_place_order() or ?place_order() to see the full list of order options, or visit

Editing orders

Once an order has been placed, it is possible to edit the order using either the orderID returned when using place_order() or the custom client order id specified using clOrdID.

For example placing the following order:

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

Could be edited using:

tn_edit_order(origClOrdID = "mybigorder", 
              price = 4000)

Cancel orders

Cancelling order is very similar to editing order, simply use the orderID or clOrdID

tn_cancel_order(clOrdID = "mybigorder")

It is also possible to cancel all orders. For example cancel all sell orders using:

tn_cancel_all_orders(filter = '{"side": "Sell"')


The get_bitmex and post_bitmex functions can be used to access additional API endpoints that do not have a dedicated wrapper.

The path argument is the API endpoint and always starts with a “/” (e.g., “/chat”). The args argument is a named list of valid parameter values to pass to the API endpoint. These are well documented on

For example, to access the user information for your testnet account you can use:

tn_get_bitmex(path = "/user", use_auth = TRUE)

As this is a private API endpoint, authentication was required.

A POST example to increase the leverage on a position is:

tn_post_bitmex(path = "/position/leverage", 
               args = list("symbol" = "XBTUSD", 
                           "leverage" = 10))

Please use the to view all possible API endpoints.
