Introducing New API Feature: execution.fast WebSocket Push

As part of our commitment to continuously improving user experience and trading efficiency, we are pleased to announce a new feature for API trading. The execution.fast topic in our API WebSocket push will be available from June 6, 2024, at 08:00 UTC.

What is execution.fast?
execution.fast is our latest enhancement to the API WebSocket push, designed to minimize the delay in obtaining execution data, thereby allowing traders to receive data in real-time. Compared to original execution data feeds, execution.fast significantly reduces Data Latency.

Supported Products:
• Contracts: for all contract trading including Perpetual and Futures

Launch Schedule:
To ensure a smooth rollout, we will open access to execution.fast in phases for specific trading pairs:
- June 4, 2024, at 08:00 UTC: All USDC Perps & Futures , All Inverse Perps & Futures
- June 5, 2024, at 08:00 UTC: All USDT Perps excluded BTCUSDT
- June 6, 2024, at 08:00 UTC: BTCUSDT

Prior to the official launch, we invite you to join us on Testnet to familiarize yourself with the execution.fast feature.

DCP (Disconnect Cancel All) will soon support Spot in addition to Contracts. As a result, Bybit will make the following API changes.

Before:
1. Get Account Info returns DCP configuration (Options), fields dcpStatus and timeWindow.

2. Set Disconnect Cancel All only supports Options.

After:
1. The Get Account Info field dcpStatus is always set to OFF and timeWindow is always set to 0.

2. A new endpoint released to query the DCP configuration: Get DCP Info. Please read the instructions carefully.

3. You can set timeWindow for each product with Set Disconnect Cancel All endpoint. A new request parameter, product, that can have the following values: SPOT, DERIVATIVES and OPTIONS (default). New error (3500716, "DCP of this UID is inactive") occurs when using not configured master account, or sub account calls the api or setting not configured product.

Make sure you submit the master account to INS manager to enable DCP on the backend first.

Scope:
* Once the master account has enabled DCP, all its subaccounts will have the same DCP by default;
* DCP is only triggered for UTA account (USDT, USDC Perp, USDC Futures, Spot and Options); classic account and inverse contract orders will not be cancelled when disconnected.
* Only the master account can call Get DCP Info and Set Disconnect Cancel All.

The above change will be implemented at 8am UTC, 4 June 2024.

Dear exchange broker users,

To fix timeout issue, Bybit will implement a change.

Before, you can query the past 6 months data

After, you can only query the past 1 month data

Affected API: Get Exchange Broker Earning

The implementation time will be started from 8am UTC, 13 June.
