# Interface Frequency Limitations
In order to protect the server from malicious attacks, there are frequency limitations for all interfaces that need to send requests to moomoo servers. The frequency limitation rules for each API are different. For more information, please see Interface Limitations at the bottom of each API page.
Example:
The limitation rule of Get Market Snapshot is: A maximum of 60 requests every 30 seconds. You can request a uniform request every 0.5 seconds. You can also quickly request 60 times, rest for 30 seconds, and then request the next round. If the frequency limitation is exceeded, an error will be returned by the interface.
# Subscription Quota & Historical Candlestick Quota
The limitation rules of subscription quota and historical candlestick quota as follows:
| User Type | Subscription Quota | Historical Candlestick Quota |
|---|---|---|
| Finished Opening trading accounts. | 100 | 100 |
| Total asset > 10,000 HKD. | 300 | 300 |
| Satisfy 1 of the items following: 1. Total asset > 500,000 HKD; 2. The number of monthly filled orders > 200; 3. Monthly trading volume > 2 million HKD. | 1000 | 1000 |
| Satisfy 1 of the items following: 1. Total asset > 5 million HKD; 2. The number of monthly filled orders > 2000; 3. Monthly trading volume > 20 million HKD. | 2000 | 2000 |
1. Total asset
Total asset, refers to all your assets in moomoo, including HK securities accounts, US securities accounts, SG securities accounts, A-shares securities accounts, Futures accounts etc., converted into HKD according to the spot exchange rate.
2. The monthly number of filled orders
It is calculated by taking the larger value of the number of filled orders the last natural month and that of the current natural month, that is:
max (the number of filled orders of the last natural month, the number of filled orders of the current natural month)
3. Monthly Trading volume
It is calculated by taking the larger value of the total trading volume of your last natural month and that of the current natural month, which is converted into HKD according to the spot exchange rate, that is:
max (the total trading volume of the last natural month, the total trading volume of the current natural month)
The calculation of futures trading value needs to be multiplied by the adjustment factor (0.1 by default). The formula for calculating futures trading volume is as follows:
Futures trading value = ∑ (volume of a single transaction * trading price * contract multiplier * exchange rate * adjustment factor)
4. Subscription Quota
It is applicable to the real-time data interface that can only be obtained after a subscription. One type of subscription for each stock takes up 1 subscription quota, and canceling the subscription will release the occupied quota.
Example:
Suppose your Subscription Quota is 100. When you subscribe to real-time order book for HK.00700, real-time ticker for US.AAPL, and real-time quotation for SH.600519 at the same time, the Subscription Quota will occupy 3, and the remaining Subscription Quota will be 97. At this time, if you cancel the real-time order book subscription of HK.00700, your Subscription Quota will become 2, and the remaining Subscription Quota will become 98.
5. Historical Candlestick Quota
Suitable for Get Historical Candlesticks interface. In the last 30 days, requests for historical candlesticks of each stock will occupy one Historical Candlestick Quota. Repeated requests for historical candlestick of the same stock within the last 30 days will not be counted repeatedly. Meanwhile, subscribing to candlestick of different periods for the same stockonly occupies one quota and will not be accumulated repeatedly.
Example:
Suppose your Historical Candlestick Quota is 100, and today is July 5, 2020. You have requested historical candlesticks for a total of 60 stocks between June 5, 2020 and July 5, 2020. The remaining Historical Candlestick Quota is 40.
Tips
- Subscription Quota and Historical Candlestick Quota are automatically assigned and do not need to be applied manually.
- For newly deposited accounts, the quota will automatically take effect within 2 hours.
- Asset in Transitwill not be calculated in quota assign.
