Native features

Set top-level signals: true and read indicators[responseKey].signals. By default features are evaluated on closed bars: true is a positive result, false a valid negative result, and null unknown. These are not trade instructions.

This indicator supports include_forming: true: treat the current final OHLCV sample as complete under the same native rules, returning one set of values, features and objects. The signal table appends bar_status: closed for closed bars, forming for a trial with confirmed_at_ms=null. A trial may disappear on later updates or at close. For BYO, still set last_bar_closed: false. Close requirements below describe the default mode; trials only admit the final sample without shortening structural windows or model confirmation requirements. See forming trials.

History lengths are minimum evaluation requirements, not convergence guarantees. Comparisons use unrounded values and the exact boundaries below. Do not turn null into false on gaps, invalid dependencies or forming bars in the default mode.

Feature column	Kind	Rule	Meaning	History / validity
kst.cross_up	event	Previous kst <= kst_signal; current kst > kst_signal.	Multi-horizon weighted momentum crosses its mean.	max(roclen1+smalen1, roclen2+smalen2, roclen3+smalen3, roclen4+smalen4) + siglen contiguous bars and valid dependencies on both bars.
kst.cross_down	event	Previous kst >= kst_signal; current kst < kst_signal.	Multi-horizon weighted momentum crosses its mean.	max(roclen1+smalen1, roclen2+smalen2, roclen3+smalen3, roclen4+smalen4) + siglen contiguous bars and valid dependencies on both bars.

See feature requests for the format and examples. /api/chart also accepts signals: true, marking confirmed events by default. With include_forming, trial events also produce markers tagged bar_status=forming; states are not drawn on every bar. See feature charts.
