An order’s status is part of the evidence

A trade idea can look complete in a note even when the order never filled. The order status is the missing fact.

Submitted, partially filled, cancelled, and rejected orders represent different exposures and different lessons.

Record the state transitions

Save the requested side and size, the time submitted, each fill, the remaining quantity, and the final status. Do not turn an intention into a position in your journal.

A cancelled order can show that the price moved, the rule changed, or your time limit worked. It is not a zero-value event.

Separate exposure from attention

Track filled size as exposure and unfilled size as a plan that may still need action. A partial fill can leave a directional position that the original thesis did not size for.

If the order was rejected, review the reason before changing the strategy. The failure may be operational rather than informational.

Review outcomes by status

Compare filled and unfilled orders separately. This reveals whether the idea worked when executable or only when a convenient quote appeared on the screen.

The useful question is not how many orders you sent. It is what each final status says about the market and the process you actually ran.
