Halt trading

The kill switch. Refuses new orders from this moment and deals with the resting ones by policy.

POST/haltself-hosted · access token · trade

Self-hosted. Served by synpath serve on your own machine or host, which must be running; the engine and its order types live there. Nothing on this page runs on Synpath's servers.

cancel calls each venue's cancel-all, reads the book back and cancels anything still resting one by one. hold leaves resting orders and refuses new ones. rearm refuses, then lifts itself after rearm_after_s.
