capitalcom

Capital.com plugin for PyneCore.

Provides historical OHLCV and live WebSocket market data, and live order execution over the Capital.com REST v1 API. Data ingest and trading share a single REST session, so one credential block serves both roles.

Both account position modes are supported. A one-way (netting) account uses the direct execute path; on a hedging-mode account connect() opts into core one-way emulation (position_port = self) and the Order Sync Engine drives close/reversal/bracket through the PositionPort primitives, presenting Pine one-way semantics over the multi-row book. Stop orders and server-side trailing stops are supported. A both-set Pine entry (limit and stop) is not a stop-limit order: the sync engine rests the limit leg natively and fires a market order on the stop side via a software price-watch, so the plugin only ever sees plain market / limit / stop entries. Partial closes are emulated via opposite-direction posts on a netting account; on a hedging account a partial close is a loud non-halting skip (DELETE /positions/{dealId} is full-row only). Size changes require cancel-and-recreate — order size is not amendable.

Idempotency is software-upheld via the unified BrokerStore — the generic order_refs table indexes each server-side dealReference / dealId so the plugin can resolve an activity tail entry back to the originating client_order_id with a single indexed SELECT. Execution events are polled from REST (/positions, /workingorders, /history/activity) since there is no WebSocket order channel.
