Protective mechanism​

The Moscow Exchange may charge a bidder an additional fee and even temporarily block the bidder if a large number of erroneous transactions are executed.

To protect our clients, we have implemented a custom blocking mechanism that allows us to eliminate errors in sent requests before the exchange takes action.

New order cancellation endpoing​

All previously available order cancellation requests let you select only one order at a time, so canceling hundreds of orders meant that hundreds of requests had to be sent and processed. To change this situation, we added a new endpoint to the HTTP API that allows you to cancel all exchange or conditional orders at once:

New parameters in requests and responses​

Requests for getting candlesticks got a new parameter instrumentGroup, allowing to specify a trading mode different from the basic one. Applies to endpoints:

The Market field containing the market section to which the specified instrument belongs has been added to the responses to requests for instrument information. Applies to endpoints:

New instrument types in GraphQL API​

To make getting data about swaps, currency pairs and unknown instruments more convenient, we have added new object types to the GraphQL API:

  • type Swap
  • type Currency
  • type UnknownInstrument

More details on how to use GraphQL API available in the corresponding article.

Docs news​

We are still developing the new documentation presented in the last digest.

In the past little while, we've:

  • Added the Astras section where we describe the features of the namesake trading terminal. This is not only a convenient tool for trading, but also a good example of using API!
  • Introduced a number of small QoL improvements like search, designed to make documentation more comfortable.

And we're also excited to announce the release of new documentation!

Along with the documentation status change, the path to the documentation has also changed — it is now available at https://alor.dev/docs/.
