Dear Traders,

Announcement: Upcoming Institutional API Rate Limit Policy
Bybit will introduce a unified rate limit cap of 60,000 transactions per second (TPS) per product line (Futures, Options, Spot). This cap applies independently by business line, allowing institutions to allocate limits flexibly across all UIDs under their structure.

Features:
• Supports tier upgrades and downgrades, with proportional scaling to ensure compliance when limits are exceeded
• Backend-assisted configuration during rollout
• Custodial structures supported: institutional cap applies across all accounts (parent and sub accounts)


The new policy is expected to launch next quarter. If you have any questions or concerns, please contact your Bybit RM within two weeks.

Dear Traders,
We would like to inform you of an upcoming change to the SPOT order price logic.

Current Behavior (Before the Change):
If a user places a limit order with a price that crosses the opposite side of the order book:
• Buy order price > system calculated maximum limit price for buy orders
The system rejects the order with: "retCode": 170193, "retMsg": "Buy order price cannot be higher than XXXX USDT."
• Sell order price < system calculated minimum limit price for sell orders
The system rejects the order with: "retCode": 170194, "retMsg": "Sell order price cannot be lower than XXXX USDT."

New Behavior (After the Change):
If such orders are submitted:
• Buy order price > system calculated maximum limit price for buy orders, The system will automatically adjust the order price to that maximum limit price
• Sell order price < system calculated minimum limit price for sell orders. The system will automatically adjust the order price to that minimum limit price.
No error will be returned. The order will proceed with the adjusted price.

Deployment Schedule:
• 2025.06.02 — Rollout to Mainnet-Grayscale
• 2025.06.16 — Rollout to Mainnet-Full

Dear Traders,

Following the previous announcement: https://t.me/Bybit_API_Announcements/317, we have decided to postpone this change after receiving feedback from users. A new rollout schedule will be announced once it is confirmed.

Dear Traders,

Bybit has improved the update frequency for insurance pool balance data.
• REST API: The Get Insurance endpoint now provides isolated insurance pool balance updates every 1 minute.
• WebSocket API: A new topic has been added. Please refer to the Insurance Pool documentation for details.

We hope these enhancements provide more timely and accurate data for your trading needs.

Dear Traders,

We would like to inform you that a fix will be applied to the Open API – Get Long/Short Ratio endpoint.

Currently, the output data may slightly deviate from the actual values due to an issue in the internal calculation service. After the fix, both real-time and historical data will reflect accurate values.

Effective Date: May 29, 2025

Thank you for your continued support and understanding.

📢 Notice of Error Code Update


Please be informed of an upcoming change on June 17, 2025 (Greyscale testing) and June 24, 2025 (Live) in our spot trading system logic:

We will adjust the order verification logic for spot trading as follows:
The system will only verify the minimum order value, and will no longer verify the minimum order quantity.
As a result, the error code 170136 ("Order quantity lower than the minimum") will be replaced with error code 170140 ("Order value exceeded lower limit").


This means that for all trading scenarios, regardless of change in market price or limit buys and sells, the error code 170136 will be replaced with error code 170140. Please note on this change to avoid any technical issues, thank you for your understanding.
