Hold off on the double until some point when white has a blot for you to shoot at. Hitting a blot will be the type of market-loser that you're looking for.
What are market losers?

A position can be

under the doubling window
in the doubling window
above the doubling window

In the first case there is no market, no market loser either

In the second case there are 2 sorts of market losers:

For instance if white throws a double,61, 31, 42 the position might go from a double to a No Double
Or (the other sort) white might throw 62 or 51 leaving a direct shot, making it a pass.

In the third case your market can be a (back)gammon market

For example: as long as the opponent has no anchor there are (back)gammons in the air.
The position might be Too Good until he anchors.

I think "Hitting a blot will be the type of market-loser that you're looking for",
should be rephrased as: "Hitting a blot will be the type of market-winner that you're looking for"

I used the phrase "market loser" like in a cash game, where you missed your opportunity to double efficiently. You're right that for a match it's more correct to say that you "missed the doubling window."

Edit: Actually, it looks like the phrase can be used in both cases.
