Trading risk-management maths as an API, computed locally and deterministically — the position-sizing and money-management numbers every disciplined trader runs before a trade. The position-size endpoint is instrument-agnostic: from an account balance, the percentage of it you are willing to risk, an entry and a stop-loss it returns the position size in units (shares, contracts, lots or coins), the cash at risk and, with a target, the potential reward and the risk-reward ratio — risk 1 % of a $10,000 account on a 50-pip stop and you trade 0.2 lots, losing exactly $100 if the stop hits. The pip-value endpoint gives the forex pip value for a lot or unit size in the quote currency, with a quote-to-account rate for non-account pairs — a standard lot at a 0.0001 pip is 10 units of the quote currency. The kelly endpoint computes the Kelly criterion optimal bet fraction f* = W − (1−W)/R from a win rate and the win/loss payoff ratio (or average win and loss), plus the half-Kelly many traders prefer and the per-unit expectancy, flagging whether the edge is positive at all. Everything is computed locally and deterministically, so it is instant and private. Ideal for trading-journal, broker, prop-firm, backtesting and fintech app developers, position-sizing and risk-management tools, and trading education. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 compute endpoints. This is risk and position-sizing maths; for FX rate conversion use a currency API and for option pricing a Black-Scholes API.

SuperTrend & Trend-Folge-API
Live-Trendfolge-Indikatoren, die Händler ausführen, um einen Trend zu reiten und seine Wende zu timen, auf Abruf aus den von Ihnen übergebenen OHLC-Kerzen berechnet – kein Key, kein Cache, nichts gespeichert. Der SuperTrend-Endpunkt gibt die SuperTrend-Linie zurück, das ATR-basierte nachlaufende Niveau, das in einem Aufwärtstrend unter dem Preis liegt (als Unterstützung) und in einem Abwärtstrend darüber (als Widerstand) und umschlägt, wenn ein Schlusskurs es kreuzt, mit dem aktuellen Trend. Der Aroon-Endpunkt gibt Aroon Up, Aroon Down und den Aroon-Oszillator zurück, die messen, wie kürzlich das höchste Hoch und das tiefste Tief erreicht wurden – ein Wert von 100 bedeutet, dass es gerade passiert ist – um Ihnen zu sagen, wie frisch und stark der Trend ist. Der Vortex-Endpunkt gibt die VI+- und VI--Linien des Vortex-Indikators zurück, deren Crossover ein klassisches Trendwechsel-Signal ist. Dies sind Trendfolge-Indikatoren, die sich bewusst vom ADX-, Parabolic-SAR- und Donchian-Set sowie von Momentum-, Volatilitäts- und Volumen-Tools unterscheiden: Sie verwenden jeweils das Hoch, Tief und den Schlusskurs, um einem Trend zu folgen und seine Umkehr mit ihrer eigenen Formel zu markieren. Funktioniert für jeden Markt – Forex, Aktien, Krypto oder Rohstoffe – weil Sie die Kerzen liefern. Lokal und deterministisch berechnet, daher sofort und privat. Ideal für Trendfolge-Bots, Signal-Dashboards und Backtests. SuperTrend-Standard: Periode 10, Multiplikator 3; Aroon: 25; Vortex: 14. Live, nichts gespeichert. 3 Compute-Endpunkte. Für ADX/Parabolic-SAR/Donchian verwenden Sie eine Trend-Indikatoren-API; für RSI/MACD eine Technische-Indikatoren-API.

Volume Indicators API
Live volume-based technical indicators that traders run to confirm a move with the volume behind it, computed on demand from the OHLCV candles you pass in — no key, no cache, nothing stored. The mfi endpoint returns the Money Flow Index, a volume-weighted version of RSI that swings from 0 to 100, with an overbought reading above 80 and oversold below 20. The obv endpoint returns On-Balance Volume, the running total that adds a candle's volume on an up close and subtracts it on a down close, together with whether it is rising or falling — rising OBV confirms buying pressure. The cmf endpoint returns the Chaikin Money Flow, which sums money-flow volume over the lookback to show whether buyers or sellers are in control. These indicators all need the volume of each candle, which makes them a fundamentally different tool from price-only indicators like RSI, MACD, Stochastic and ADX: they answer whether volume is confirming the price move or diverging from it. Works for any market — forex, stocks, crypto or commodities — because you supply the candles with volume. Computed locally and deterministically, so it is instant and private. Ideal for trading bots, divergence screeners, breakout confirmation and trading dashboards. Candles are open:high:low:close:volume. Live, nothing stored. 3 compute endpoints. For price-only indicators use a technical-indicators, oscillators or trend-indicators API.

Trend Indicators API
Live trend and direction indicators that traders run to gauge whether a market is trending and which way, computed on demand from the OHLC candles you pass in — no key, no cache, nothing stored. The adx endpoint returns the ADX (Average Directional Index) with the +DI and -DI lines using Wilder's method, so you get both the strength of a trend (a reading above 25 signals a real trend) and its direction. The psar endpoint returns the Parabolic SAR — the trailing stop-and-reverse level that sits below price in an uptrend and above it in a downtrend, and flips when price crosses it — together with the current trend. The donchian endpoint returns the Donchian Channel: the highest high and lowest low over the lookback with the midline, and whether the last close has broken out of the channel. These indicators all need the full high, low and close, and they answer a different question than momentum oscillators, closes-only indicators or volatility tools: is there a trend, and which way is it going. Works for any market — forex, stocks, crypto or commodities. Computed locally and deterministically, so it is instant and private. Ideal for trend-following bots, breakout screeners, trailing-stop logic and trading dashboards. ADX needs 2 x period + 1 candles. Live, nothing stored. 3 compute endpoints. For RSI/MACD use a technical-indicators API; for Stochastic/CCI use an oscillators API.

Trade Setup & R:R Planner API
Live-Trade-Planungsanalysen, basierend auf der Geometrie eines Setups, den Zahlen, die ein Trader vor dem Auslösen prüft, auf Abruf berechnet aus dem Einstieg, Stop und Ziel, die Sie übergeben — kein Key, kein Cache, nichts gespeichert. Der Plan-Endpunkt wandelt einen Einstieg, Stop-Loss und Ziel in das Risiko und die Belohnung pro Einheit, das Belohnungs-Risiko-Verhältnis und die Break-Even-Gewinnrate — die Mindestgewinnrate, die den Trade profitabel macht — und, wenn Sie eine Kontogröße und einen Risikoprozentsatz angeben, die Positionsgröße, den Risikobetrag und den Belohnungsbetrag. Der Targets-Endpunkt projiziert Zielkurse bei ausgewählten R-Vielfachen des Stop-Abstands, sodass Sie bei 1R, 2R und 3R aussteigen können. Der Expectancy-Endpunkt wandelt ein Belohnungs-Risiko-Verhältnis und eine Gewinnrate in den erwarteten Wert pro Trade in R und den Profitfaktor um und zeigt Ihnen, ob ein Edge positiv ist. Dies ist ein Trade-Geometrie-Planer, der sich grundlegend von kontobasierten Positionsgrößenrechnern, vorwärtsgerichteten Monte-Carlo-Simulationen und rückwärtsgerichteten Trade-Journal-Analysatoren unterscheidet: Er argumentiert vom Einstieg, Stop und Ziel. Funktioniert für jeden Markt — Forex, Aktien, Krypto oder Futures — und für Long oder Short. Lokal und deterministisch berechnet, daher sofort und privat. Ideal für Trade-Journale, Risikochecklisten, Broker-Tools und Trading-Dashboards. Live, nichts gespeichert. 3 Compute-Endpunkte. Für Kelly-Positionsgrößenbestimmung verwenden Sie eine Trading-Risk-API; für eine vollständige Ergebnisverteilung einen Strategie-Simulator.
