}Hedges
Add to a Hedge
Increases your existing open hedge on a market+side by adding notional, keeping the same maturity - the convenience form for the desk, which knows the market and side but not the hedge id. Resolves the open hedge server-side. Returns 404 no_open_hedge if you don’t have one on that side (open one instead). Pass an Idempotency-Key to make retries safe.
