To optimize resource allocation and continually enhance the trading experience, we will implement adjustments to the order entry rate limiting rules for the Perpetual Futures API, effective October 12, 2024, at 08:00 UTC.

1.Current Rate Limit Rules for Perpetual Futures

1.Requests (order placement, modification, and cancellation) Exceeding 7,200 Without Any Fills
-Condition: If a user sends over 7,200 requests within one hour without any order fills.
-Limitation: Order placement rate limit will be restricted to 20r/10s for the next hour.
2.Requests Exceeding 7,200 with Fill Ratio Below 1%
-Condition: If a user sends over 7,200 requests within one hour, and the fill ratio is below 1%.
-Limitation: Order placement rate limit will be restricted to 30r/10s for the next hour.

2.Adjustments to Rate Limit Rules

The principal adjustment entails extending the statistical period from an hourly basis to the most recent 24-hour period. The specific modifications are as follows:
1.Statistical Period
-Statistical Period: Data will be accumulated over the most recent 24 hours, with statistics updated hourly.
2.Request Types (order placement, modification, and cancellation)
-Statistics Items: All requests, including successful and failed order placements, cancellations, and modifications (e.g., passive order fills, insufficient funds)will be counted.
3.Rate Limit Rules
-Absence of Fills
-Condition: If the number of requests exceeds 86,400 within 24 hours, with no order fill in the same period.
-Limitation: Order placement rate will be restricted to 10r/10s for the next hour.
-Fill Ratio Below 1%
-Condition: If the number of requests exceeds 86,400 within 24 hours, with the fill ratio below 1%.
-Limitation: Order placement rate will be restricted to 20r/10s for the next hour.
4.Unlock Mechanism
-The system will conduct a dynamic assessment of users’ trading activities. Upon detecting that a user’s strategy has been appropriately adjusted and aligns with our efficiency standards, the imposed restrictions will be lifted.
-Explanation:
-Every hour, the system calculates the fill ratio for the past 24 hours, applying a restriction for at least one hour. If a user is restricted in the current hour as the fill ratio is recalculated hourly, the restriction will be lifted when the fill ratio exceeds the threshold.

3.Calculation of Fill Ratio

The Fill Ratio is determined using the following formula:
Fill Ratio = (Trade Volume in USDT)/ (sum of new and modification and cancellation requests)
