Saving & trading

Save adds a spread to your watchlist; Execute records a real trade. Why they're separate.

There are two ways to commit to a candidate, and they mean different things.

Save — add it to your watchlist

Save captures the spread as a watched idea. It records the structure and a suggested (risk-based) size as a target — but it does not create a position, and it deliberately doesn't ask for a thesis or review triggers yet. No money is at risk.

Use Save when a candidate is interesting and you want to track it without trading today. A watched idea sits in the Saved Spreads lane under "Watchlist," and you can stop watching it any time.

Execute — trade this

When you're ready to put it on, open a watched idea and choose Trade this. Execute records the real trade:

  • the final size (pre-filled from the watched target, overridable),
  • the traded price — your actual fill, not a modeled mid,
  • your thesis — why you put it on and what would change your mind,
  • your review triggerswhen something happens, then what you'll do.

Executing flips the spread from Watching to Open. From here it's a live position with a plan, and its P/L is scaled to the size and fill you entered.

Why they're separate

A free-form "looks good" note at save time is journaling, not commitment. Ideas and positions are different objects with different fields — so the thesis, the triggers, and the final size live with the trade, where they belong, not with a bookmark. It also means your watchlist stays a clean list of candidates, not a pile of half-formed plans.

| | Save | Execute (Trade this) | |---|---|---| | Creates | a watched idea | a live position | | State | Watching | Open | | Captures | structure + target size | final size, fill price, thesis, triggers | | Risk | none | real |

Once it's open, manage it: Managing a position.
