summary: Live technical signal
description: 'Current technical-analysis signal for a stock, FX pair, crypto asset, or commodity: a decision-ready summary (strong_sell to strong_buy) with a score from -1 to +1, plus the oscillator and moving-average indicators behind it, each with its value(s) and vote. Indicators still in warmup are omitted, so the vote counts sum to the rows returned. `price.bar_status` is `forming` when a live tick is folded into the current bar, `closed` when the last settled bar is used.'

summary: Historical technical-signal series
description: 'The technical-analysis signal as a time series, one point per bar: summary, score, close, and any discrete events (golden_cross, death_cross, macd_cross_up, macd_cross_down) that fired on that bar. Same computation as the live signal, so a historical point is identical to the one that fired live. `t` is the bar-open time in Unix epoch milliseconds, the same as the `/v1/hist/*` bars routes.'
