The Sell Flow

When SignalPipe receives a sell signal, it closes all sub-positions for the specified instrument.

Sell Execution Steps

1. Close all sub-positions -- Each open sub-position in the deal is individually closed on Capital.com. This is necessary because Capital.com manages each DCA position as a separate deal.
2. Collect profit data -- Capital.com returns profit/loss data for each closed sub-position in the confirmation response.
3. Calculate total P&L -- The realized profit or loss is summed across all closed sub-positions.
4. Mark deal as completed -- The deal status is updated to "completed" with the close timestamp and total realized P&L.
5. Log the closure -- A detailed log entry records the P&L, number of sub-positions, and ladder depth.

Example: Sell Flow

• Active deal: AAPL, 2 sub-positions (base + 1 safety order), 25 total units, avg entry $144.00
• Sub-positions closed individually on Capital.com
• Combined P&L from confirmations: +$100.00
• All sub-positions marked CLOSED
• Deal marked completed

Edge Cases

No Active Deal Found

If a sell signal arrives but there is no active deal in the database for that instrument, a warning is logged noting that no matching deal was found. This can happen if:

• The deal was already completed by a take-profit fill
• The deal was closed manually on Capital.com
• The position was opened outside of SignalPipe

Position Already Closed

If a Capital.com sub-position was already closed (for example, by a TP level being hit), the close request may return an error. SignalPipe handles this gracefully -- it logs the situation and continues processing the remaining sub-positions.
