A condition isn't watched or can't be saved

The Condition button is missing. By design for workspaces and closed trades. Conditions belong to a draft or open trade.

“Watched once the trade is open”. By design on a draft.

“Not watched: …”. The reason follows: IB or thinkorswim is disconnected, waiting for quotes, the trade holds stock or futures beside its options, its options are on more than one underlying, or the trade holds no open option.

“No data: no fresh SPX price”. The condition needs a quote and has none. After 5 minutes of missing data the mark resets.

“No longer held”. A price level measured from a leg works only while the trade holds that leg. Edit the condition to pick another.

Save is disabled in the dialog. Hover Save to read why, such as a price of zero or a missing leg.
