MngUpdateOpenTrade

Description: Allows a manager to update an already open trade. Updates fields such as SL/TP, volume, price, symbol, and time. The trade must be in an open state.

Access Control

Requires set_trades for manager/dealer sessions. The target account must also match the manager groups and brand scope loaded from the cached manager record. Token payload is used only for manager id and session type.

Admission is synchronous under the cached-order lock; calculation completion remains asynchronous. Closing/finalized trades and competing in-flight requests are rejected before acknowledgment. SL/TP closing uses the same reservation: an accepted update is evaluated with its updated protection, while a close that wins admission rejects the update. Late updates cannot produce OPEN after CLOSED or recreate floating profit/margin. The same admission rule applies to MngUpdateOpenTradeSync and the open-position branch of MngUpdateTradeSync; their success responses still wait for the matching runtime event.

Copy-Follower Manual-Write Checks

For SESSION_USER or SESSION_CUSTOMER requests, this mutation applies the copy-follower manual_trading_mode after the usual account/order ownership checks. The check applies only when the target account has an enabled follower profile. Mode 0 rejects all manual writes; mode 1 permits new or non-copied orders but rejects changes to linked copied orders; mode 2 permits both. Manager/admin/dealer staff sessions bypass this follower policy.

HTTP	Error	Message
403	COPY_MANUAL_TRADING_DISABLED	Manual trading is disabled for this copy follower
403	COPY_COPIED_ORDER_MANUAL_FORBIDDEN	Manual changes to copied orders are disabled for this copy follower

The command returns the denial for its target login or order without accepting that mutation.
