Identify source and target from the label
The view can add the other market’s call wall, put wall and zero gamma. Labels identify their origin, such as “SPX Call Wall → NQ”. Distinguish these additional references from the active market’s own levels. A call wall from a different source does not answer the same question.
Use the additional context deliberately
Start with the market you trade and add the other market’s references when useful. Check whether an observable response occurs there. An overlaid level is an additional reference point; it is neither an order nor a promise that price will reach or reverse at that area.
ES and NQ have different compositions and can respond differently. Do not compare absolute index points as if both markets used the same scale. For your review, record which reference you saw before entry and its role in your setup.
Keep the timestamp with the trade evidence
Check the displayed data timestamps and selected view, especially when reviewing an earlier session. A current chart and older options information do not describe the same moment. Missing data should not be interpreted as missing market interest.
Record source, active market, time and your observation in the journal. Assess the additional market context separately from trade execution quality. A decision can follow the plan and still lose; the later move alone does not establish whether you recorded the entry-time context correctly.
