Pairwise Close By Opposite Positions

A hedged book often ends up with a buy and a sell open on the same symbol at the same time - a manual hedge, a grid that filled both ways, or two EAs working the same pair. Closing both legs independently at market pays the spread twice, once on each ticket, for a position pair whose net exposure was already flat. OrderCloseBy settles two opposite tickets against each other in a single broker-side operation. The matched volume - the smaller of the two lot sizes - cancels out at the two orders' own open prices rather than at the current market price, so only the unmatched remainder, if any, ever crosses the spread. The saving is real money on a book that hedges often, and it is entirely broker-dependent: not every broker supports close-by, and some disable it per account type. This script checks by attempting it and reports the failure plainly rather than pretending every broker behaves the same way. Pairing is done by symbol and direction: any two open tickets on the same symbol with opposite market direction are eligible. By default both tickets must also share the same magic number, since pairing an EA's hedge against an unrelated manual trade can produce a result the EA does not expect - this can be relaxed with an input for a book that is deliberately managed as one unit regardless of who opened each leg. Every proposed pair is listed in the journal with both ticket numbers, symbol, direction and lot size before anything is touched, and the script asks for confirmation by default. Notes and limitations - Hedging accounts only. Close-by requires two independent opposite tickets on the same symbol, which cannot exist on a netting account - a netting account merges opposing fills into one position before this script ever sees them, so there is nothing for it to pair. - Not every broker supports OrderCloseBy. If the broker refuses it, every attempt fails with the same error code and the script reports it rather than falling back to a plain close silently. - Pairing is greedy: the first eligible opposite ticket found for a given order is the one it is paired with. On a book with several tickets per side and per symbol this may not choose the pairing that minimises the unmatched remainder - it chooses a valid one, not necessarily the optimal one. - Unequal lot sizes leave a remainder on the larger ticket after close-by. That remainder is not automatically closed separately; it stays open under its original ticket for a later run or manual action. - The script runs once. It is not a background monitor that pairs new opposite tickets as they appear.
