Deriv messages

Risk warning: CFDs and spread bets are complex instruments and come with a high risk of losing money rapidly due to leverage. You can lose money on these products, and each provider publishes its own loss figure under FCA rules. You should consider whether you understand how they work and whether you can afford to take the high risk of losing your money. Automated and API trading can amplify losses through bugs, connectivity failures and runaway orders.
These are messages and subscriptions carried by a connection that stays open, not HTTP endpoints: none has a method or a path. For that reason they are in no OpenAPI file on this site and the request builder does not list them. A message that is not listed is not recorded here, which is not evidence that it does not exist.
Account

Connection and subscriptions
4 messages
- forgetStops one stream at once, by the id the stream's own messages carry in subscription.id. This is how a subscription is ended.
- forget_allStops every stream of one type on the connection, or of several types at once, and returns the ids of the streams it stopped.
- pingAsks the server to answer pong. It tests that the connection is alive and is the usual way to keep an idle one open.
- timeReturns the server's clock, as Unix time in seconds. Useful for checking your own clock before working with epochs.
Market data
4 messages
- active_symbolsLists the symbols that can be traded now, with the market each belongs to and whether it is open. The symbol codes it returns are what ticks, ticks_history and proposal expect.
- contracts_forLists the contracts that can be bought on one symbol now, with the barrier, stake and duration limits of each. On a logged in connection only the contracts that account may trade are returned.
- ticksAsks for the latest price of one symbol or several. With subscribe set to 1 a new tick message follows each time the price changes, until the stream is stopped with forget.
- ticks_historyReturns past prices of one symbol, as single ticks or as candles of a chosen width. With subscribe set to 1 it then keeps sending each new tick or the candle now forming.
Trading
6 messages
- buyBuys a contract: either the one a proposal priced, by the id that proposal returned, or one described in full in parameters. price is the most you accept to pay.
- cancelCancels an open contract by its contract id. The answer is a receipt in the same shape as the one sell returns.
- contract_updateChanges the stop loss or the take profit of an open contract, or removes one by sending null for it.
- proposalAsks what one contract would cost now: the price, the payout and a description of it, with an id that buy accepts. With subscribe set to 1 the price is sent again as it changes.
- proposal_open_contractReturns the current price and state of a contract the account holds. With subscribe set to 1 an update follows each time it changes, and with no contract_id the stream covers every open contract.
- sellSells an open contract back before it ends, by its contract id. price is the least you accept, and 0 means sell at the market.
