LIMITS

Order Count Limits * To keep an orderly market, jex imposes limits on the number of open orders per account. These limits are: * Maximum 200 open orders per contract per account; * Maximum 10 stop profit or stop orders per contract per account; * When placing a new order that causes these caps to be exceeded, it will be rejected with the message “has reach max order number [200|10]”.

Other instructions The number of contract orders sells for API is uniformly negative

Endpoint security type

Security Type Description
NONE Endpoint can be accessed freely.
TRADE Endpoint requires sending a valid API-Key and signature
USER_DATA Endpoint requires sending a valid API-Key and signature.
USER_STREAM Endpoint requires sending a valid API-Key.
MARKET_DATA Endpoint requires sending a valid API-Key.

SIGNED (TRADE and USER_DATA) Endpoint security

Timing security * A SIGNED endpoint also requires a parameter, timestamp, to be sent which should be the millisecond timestamp of when the request was created and sent. * An additional parameter, recvWindow, may be sent to specify the number of milliseconds after timestamp the request is valid for. If recvWindow is not sent, it defaults to 5000. * The logic is as follows: javascript if (timestamp < (serverTime + 1000) && (serverTime - timestamp) <= recvWindow) { // process request } else { // reject request } Serious trading is about timing. Networks can be unstable and unreliable, which can lead to requests taking varying amounts of time to reach the servers. With recvWindow, you can specify that the request must be processed within a certain number of milliseconds or be rejected by the server.
