Stochastic API — %K and %D Crossovers
Get both %K and %D lines as JSON. Detect bullish and bearish crossovers in overbought (>80) or oversold (<20) territory programmatically.
No credit card. $2.50 PAYG credit on sign up.
What is the Stochastic Oscillator API?
The Stochastic Oscillator compares the closing price to its price range over a given period, producing %K (fast line) and %D (3-period SMA of %K, slow line). Values above 80 indicate overbought; below 20, oversold. When %K crosses above %D inside an oversold zone, it's a classic long entry signal. TickAtlas pre-calculates both lines from live broker data, so your strategy gets the crossover signal without any raw candle processing.

Credits, Not Minutes
WebSocket streaming is billed per price push, not per connection minute. Each time the server sends you a quote, it deducts credits from your daily quota:
- Starter: 5 credits per price push. Subscribe to 5 symbols updating every 60s = ~7,200 credits/day.
- Pro: 4 credits per push. 20 symbols = ~57,600 credits/day. Lower per-push cost rewards higher volume.
- Enterprise: 3 credits per push. Unlimited symbols. Lowest cost per data point.
Daily quotas reset at midnight UTC. If your quota runs out, the server stops pushing data but keeps the connection open. You resume receiving quotes when your quota resets or you upgrade.
Code Examples
Python — websocket-client
import json, websocket
def on_open(ws):
ws.send(json.dumps({"action": "auth", "key": "YOUR_API_KEY"}))
def on_message(ws, raw):
msg = json.loads(raw)
if msg["type"] == "authenticated":
ws.send(json.dumps({"action": "subscribe",
"symbols": ["EURUSD", "XAUUSD"]}))
elif msg["type"] == "quote":
q = msg["data"]
print(q["symbol"], "bid", q["bid"], "ask", q["ask"])
ws = websocket.WebSocketApp(
"wss://tickatlas.com/ws/v1/quotes",
on_open=on_open, on_message=on_message,
)
ws.run_forever()JavaScript — Browser / Node.js
const ws = new WebSocket("wss://tickatlas.com/ws/v1/quotes");
ws.onopen = () => {
ws.send(JSON.stringify({ action: "auth", key: "YOUR_API_KEY" }));
};
ws.onmessage = (event) => {
const msg = JSON.parse(event.data);
if (msg.type === "authenticated") {
ws.send(JSON.stringify({
action: "subscribe",
symbols: ["EURUSD", "XAUUSD"],
}));
} else if (msg.type === "quote") {
const q = msg.data;
console.log(q.symbol, "bid=" + q.bid, "ask=" + q.ask);
}

Get StartedFrequently Asked Questions
What Stochastic parameters does the API use?
The fast Stochastic (5,3,3) — a 5-period %K, smoothed to 3 periods for the displayed %K, and a 3-period SMA for %D. This is a common short-term momentum setting, faster than the slow Stochastic (14,3,3).
What's the difference between Stochastic_K and Stochastic_D?
Stochastic_K is the fast line — it reacts quickly to price. Stochastic_D is the 3-period moving average of %K — smoother and slower. Crossovers in overbought/oversold zones are the classic entry signals.
Can I use Stochastic with RSI for confluence?
Yes — both are on the same API. A common setup: Stochastic %K below 20 AND RSI below 30 = double-confirmed oversold. Both signals fire from the same endpoint with a different indicator name parameter.
Does Stochastic work well on M1 timeframes?
It produces more false signals on M1 due to noise. H1 and H4 are where Stochastic oversold/overbought levels are most reliable. M5 can work for scalpers who use additional filters like ADX.
