Notes​

Precisions​

Paxos quantity precision is 4, price - 2

Cancel On Disconnect​

Cancel on Disconnect is an Paxos FIX API feature that will automatically submit a request to the exchange to cancel all open FIX orders whenever you disconnect from the FIX API. It is enabled by default.

Account​

Paxos customer_id is sent as Account(1), and profile_id is sent as ClientID(109). Account(1) is required for new, cancel and status requests.

Orders​

Supported order types are Limit, Market Sell, Stop Market Sell and Stop Limit Sell. Market Buy is not supported because it requires CashOrderQty(152), which this connector intentionally does not send.

Good Till Cancel, Immediate or Cancel, Fill or Kill and Good Till Date are supported according to Paxos order-type rules. Good Till Date is sent as TimeInForce(59)=6 with ExpireTime(126).

Post-only limit orders can be sent with ExecInst(18)=6.

Only Limit orders can be Post-only.

Symbology​

Schedule​

The exact time when the disconnect and reset to sequence numbers happen is discussed during the onboarding process. Clients must configure their FIX engines to expect a disconnect and sequence number reset at the agreed schedule, failure to do so will result in an invalid FIX session due to mismatching sequence numbers.
