Supported indicators, anchors, and rule primitives.

Trend indicators help describe whether price is above, below, reclaiming, rejecting, or holding around a directional reference. In the current public language surface, that includes moving-average and related trend-style references traders already recognize.

These are useful when combined with anchors, comparators, sequence, and persistence rather than treated as a one-line signal by themselves.

Momentum indicators can help express whether a move is strengthening, weakening, stretching, or reverting. Examples already consistent with the current page include RSI, DMI/ADX-style momentum context, stochastic conditions, and related directional-strength checks.

Volatility indicators matter when a rule depends on range expansion, contraction, band interaction, or a change in trading conditions rather than just directional bias.

Public-facing examples here include Bollinger Bands, ATR, Keltner-style envelopes, and band-state language that can be combined with sequence and persistence rules.

Volume-oriented language helps describe whether participation is increasing, fading, or behaving unusually relative to recent context.

This stays in the language surface as supporting context, not as fake proof or a promise that one volume read can decide a setup by itself.

VWAP is one of the most important intraday references in the Lexicon QDL language surface because traders often use it together with anchors, sequence, and persistence rather than as a standalone line.

A rule may use structures such as CLOSE CROSSUP VWAP for reclaim or cross-up behaviour, CLOSE CROSSDOWN VWAP for rejection or cross-back-below behaviour, and CLOSE > VWAP FOR 5 BARS for hold-above or persistence behaviour. Traders may still describe reclaim, reject, or hold behaviour in normal prose, but those behaviours should not be presented here as official V1 token chips.

Lexicon can express rule logic around price-reference and structure concepts, but raw OHLC fields are not the public feature pillar of this page. The main point is how price references interact with indicators, anchors, comparators, and sequence.

That means structure-aware conditions can support setup definition without turning raw OHLC into the headline story.

Anchor families are central to the language surface because many setups depend on prior levels, opening structure, session ranges, and time-window references rather than on indicators alone.

In plain language, that includes prior-day levels, current-day levels, prior-day close, current-day open, opening print, first 5-minute highs and lows, first 15-minute highs and lows, opening range highs and lows, custom window levels, session highs and lows, Asia/London/New York levels, NY AM / NY PM levels, 90-minute cycle levels, and open-price anchors.

Comparator and qualifier families let a trader express whether something was greater than, less than, equal, not equal, crossing, holding, stretching, fading, or breaking for the first time.

This is what helps Lexicon describe setup behaviour more precisely than a single above/below test.

Sequence and persistence tools help a trader express that one condition happened, another condition followed, and the combined setup needed to persist long enough to matter before an entry is allowed.

These primitives are part of why the language surface is about structured setup definitions rather than one signal firing in isolation.
