HTF-level Proximity Filters

What are HTF-level Proximity Filters?

An HTF-level proximity filter gates lower-timeframe signals by their distance to higher-timeframe levels. The mechanics are simple: maintain a set of levels computed on a higher timeframe, such as prior period levels, pivots, or untested zones; measure current price's distance to the nearest one, usually normalized in ATR multiples or percent; and allow or suppress the signal based on that distance. It runs in two modes: require proximity, so entries only count when they fire at a level, or require clearance, so a long triggered directly beneath higher-timeframe resistance is discarded because its room to run may be capped before it starts.

The filter turns the top-down habit, trade the lower timeframe only where the higher timeframe agrees, into checkable arithmetic. Its output is only as good as its level set: feed it too many levels and everything is near one, feed it too few and valid locations are missed. Implementations therefore tend to cap the number of active levels per side and prefer fresh, untested ones.

How traders use it

• As a veto: suppress longs within a set distance below higher-timeframe resistance and shorts just above higher-timeframe support, removing trades whose first obstacle arrives almost immediately.
• As entry qualification: the inverse mode accepts lower-timeframe reversal triggers only when they print at a higher-timeframe level, the familiar pattern of dropping down a timeframe to confirm a location before committing.
• As target logic: the same distance calculation ranks which level sits first in the trade's path, informing where targets or partial exits belong rather than whether to enter.
