Hi,

@cTrader

I have gone through Open API documentation and found that there are some limitations as it saying:

Note that there exist some limits on how many times you can perform certain requests to the cTrader backend.

You can perform a maximum of 50 requests per second per connection for any non-historical data requests.
You can perform a maximum of 5 requests per second per connection for any historical data requests.

My question is that if user A is connected to OpenAPI app X, and user B is also connected with app X, then 50 request limit would be for both users collectively or individually?

Hi there,

There limits are per connection, no matter how many users are authorized through it.

We are getting this error message:

payloadType: 'PROTO_OA_ERROR_RES',ctidTraderAccountId: '0',errorCode: 'REQUEST_FREQUENCY_EXCEEDED',description: 'You have reached the rate limit of requests',maintenanceEndTimestamp: null,clientMsgId: 'dde6ab71-0c46-11ee-bb08-13881ab8dd11'

It especially comes when you are iterating trades for a user. What could be the reason?

Hi there,

I think the message is clear. You have reached one of the above limits.

It means when we access broker accounts through Open API then we created a single connection, no matter how many users are linked with it and these limits are for this connection. Am I right?
