#breakout

Which markets are breaking out of their volatility-adjusted trend channel, computed live from Yahoo Finance (no key, nothing stored). Keltner Channels wrap a 20-day exponential average in bands set at two Average-True-Ranges above and below it — and unlike Bollinger Bands, whose width is statistical standard deviation, Keltner's width is the market's actual trading range. A close above the upper Keltner band is a trend-following breakout (riding strength), below the lower a breakdown, and price hugging a band signals a powerful, persistent trend. For a cross-asset, cross-sector universe — equity indices and sectors, gold, oil, commodities, bonds and crypto — this computes each asset's Keltner upper, middle and lower bands, where price sits inside the channel, and flags fresh breakouts. The screener endpoint returns the upside and downside Keltner breakouts across the board. The asset endpoint returns one market's Keltner card. The universe endpoint lists what is covered. The cross-asset Keltner-channel / volatility-trend screener cut — distinct from the Bollinger-Bands screener (standard-deviation width, mean-reversion), the bring-your-own-candle ATR API and the other indicator screeners.

Which markets are breaking out of their recent trading range, computed live from Yahoo Finance (no key, nothing stored). The Donchian channel — the highest high and lowest low of the last N days — is the breakout system the legendary Turtle traders rode: a close above the 20-day high is a classic long entry, below the 20-day low a short, and the 55-day channel is the slower, higher-conviction version. For a cross-asset, cross-sector universe — equity indices and sectors, gold, oil, commodities, bonds and crypto — this computes each asset's 20-day and 55-day Donchian channels (upper, lower and midline), where price sits inside the 20-day channel, and flags fresh breakouts above the high or below the low. The screener endpoint returns the upside and downside breakouts across the board plus the channel-position ranking. The asset endpoint returns one market's Donchian card. The universe endpoint lists what is covered. The cross-asset Donchian / channel-breakout (Turtle) screener cut — distinct from the crypto-only Donchian screener, the 52-week-range screener (a much longer window), the Bollinger-Bands screener and the bring-your-own-candle indicator APIs. It catches the range breakouts across every asset class at once.

Which markets are coiled for a breakout and which are stretched to their bands, computed live from Yahoo Finance (no key, nothing stored). Bollinger Bands wrap a 20-day average in plus/minus two standard deviations; price riding the upper band is strong, the lower band weak, and — the prized signal — when the bands pinch tight (a "squeeze"), volatility has compressed and a big move usually follows. For a cross-asset, cross-sector universe — equity indices and sectors, gold, oil, commodities, bonds and crypto — this computes each asset's bands, its %B (where price sits between the lower band at 0 and the upper at 100), the bandwidth and whether bandwidth is at a multi-month low (a squeeze, breakout pending). The screener endpoint returns the board with the markets in a squeeze, the ones breaking above the upper band and the ones breaking below the lower. The asset endpoint returns one market's Bollinger card. The universe endpoint lists what is covered. The Bollinger Bands / volatility-squeeze screener cut — distinct from the bring-your-own-candle technical-indicator APIs, the FX-only z-score API and the market-breadth API. It finds the coiled springs across the whole market.

Where every major asset sits in its one-year range — across stocks, indices, bonds, commodities, FX and crypto — computed live from Yahoo Finance (no key, nothing stored). The 52-week high/low is the single most-watched level in markets: assets breaking to new 52-week highs are in confirmed uptrends and chased by momentum, while new 52-week lows mark capitulation, and the "new highs / new lows" list is a classic breadth and momentum read. This places each instrument in its range as a 0-100 position (0 = sitting on its 52-week low, 100 = at its 52-week high), with how far it is below the high and above the low, and flags fresh new highs and new lows. The screener endpoint returns the whole multi-asset universe ranked by range position — what is breaking out at the top and breaking down at the bottom — plus the new-high and new-low lists. The asset endpoint drills into one instrument. The universe endpoint lists what is covered. The 52-week-range / new-highs-new-lows momentum cut across asset classes — distinct from the crypto Donchian-breakout screener (crypto only) and the single-quote, index, commodity and stock price feeds, which carry the 52-week high/low as a field but do not rank it across a multi-asset book.

Which coins are breaking out of their recent trading range, computed live from Binance candles — no key, nothing stored. The Donchian channel is the highest high and lowest low of the last N periods; a price above the upper band is a classic trend-following breakout (the original turtle-trading signal) and a price below the lower band a breakdown. The breakout endpoint returns, for one pair, the N-day Donchian upper and lower bands, the current price, where it sits in the channel (0% at the low, 100% at the high), the distance to each band and a status — new_high, new_low, near_high, near_low or inside. The screener endpoint scans a basket of coins and surfaces the ones currently breaking to new highs (momentum-long candidates) and to new lows (breakdowns), ranked by how decisively they have cleared the band. The symbols endpoint lists tradable pairs. This is the range-breakout / Donchian-screener cut for crypto — distinct from the generic indicator calculators (which you feed your own data), the volume-profile, the seasonality and the order-flow APIs in the catalogue. Bands use the prior completed candles, so a breakout is a genuine move beyond the established range. Pairs are Binance symbols (BTCUSDT) or a coin=BTC&quote=USDT form; lookback is 5-200 days.
