Bot safe stop

A safe stop is a client-side workflow: cancel open orders, then stop submitting new creates and replaces. There is no server-side account cancel-only or trading-halt mode. The only cancel-only-style flag in order flow is per-order reduce_only, which constrains exposure but does not halt an account.

Raw workflow

Stop local create and replace producers.
Record a cutoff max_ts.
Send cancel-all with that cutoff.
Keep the order-control or orders WebSocket open until terminal events arrive.
Re-fetch complete account state and reconcile.

curl -X DELETE "https://oms.tplus.cx/orders/cancel-all?max_ts=$STOP_TS_NS" \
  -H "Authorization: Bearer $TOKEN" \
  -H "User-Id: $USER_ID"

In-flight creates or replaces that were already accepted before max_ts can still race with the cancel. Watch the orders stream and refetch:

curl -H "Authorization: Bearer $TOKEN" -H "User-Id: $USER_ID" \
  "https://oms.tplus.cx/orders/user/$USER_ID?page=0&limit=100"

curl -H "Authorization: Bearer $TOKEN" -H "User-Id: $USER_ID" \
  "https://oms.tplus.cx/inventory/user/$USER_ID"

tpluspy

import time

stop_ts = time.time_ns()
disable_strategy_writes()

await client._request("DELETE", "/orders/cancel-all", params={"max_ts": stop_ts})

open_orders, raw_orders = await client.get_user_orders()
inventory = await client.get_user_inventory()
margin = await client.get_user_margin_info(include_positions=True)

If using OrderBookClient(use_ws_control=True), send create, replace, and cancel through the same /control channel so responses carry the same connection context. On reconnect, do not resume from memory: fetch open orders, positions, inventory, margin, and recent user trades before restarting quoting. The /control channel also accepts CancelAllOrdersRequest, CancelAllOrdersForAssetRequest, and BatchCancelRequest raw messages, or v1 envelopes with request_id. Bulk cancel messages are acknowledged as submitted; reconcile individual order state through the orders stream and REST snapshots.

Reconciliation checklist

Surface	Use
`/orders/user/{user_id}`	Remaining open or in-flight orders
`/trades/user/{user_id}`	Recent confirmed fills
`/positions/{user_id}`	Open margin positions
`/inventory/user/{user_id}`	Spot and margin balances
`/margin/user/{user_id}`	IM/MM state after stop
`/account/events/{user_id}`	Deposits, withdrawals, transfers, position clears

For market makers on sync books, also watch /sync/pending_settlements; a stopped quoting loop can still have settlement obligations for fills that already happened.
