Chart It. Validate It. Ship the Code.
Configure any OHLC query visually, see the real data in the chart, then copy the generated request straight into your trading algorithm, backtesting script, or data pipeline.
Three OHLC chart styles for every market data workflow
Candlestick
Line Chart
Area Chart
Live Streaming
Flexible Intervals
Date Range Control
The chart tells you the code is right
Unlike a plain API explorer, the Chart Builder lets you see the OHLC data before you write anything. Adjust the symbol, date window, and interval until the chart looks exactly right — then copy the generated request and integrate it into your application with confidence. Full API reference in the docs.
The generated OHLC API request reflects exactly what you configured in the chart — symbol, resolution, start, and end timestamps. Copy it once and it runs. No parameter mapping, no docs diving. If you want to dig deeper, the full OHLC endpoint reference is in the documentation.
Pull the exact OHLC window your strategy needs. Validate the data visually in the chart, then feed the same request into your backtest engine.
df = pd.DataFrame(data["items"])
# run your strategy on confirmed OHLC data
signals = strategy.backtest(df)
Use the 1-minute or 1-hour OHLC stream as the data source for your execution logic. The chart lets you eyeball the signal quality before going live.
while True:
candles = fetch_ohlc("GBPCHF", resolution=3600)
if signal(candles):
execute_trade()
Drop the OHLC endpoint into any frontend chart library. The Chart Builder gives you the exact URL and headers your component needs to render the same data.
const data = await fetch(
"…/currencies/GBPCHF/ohlc?…",
{ headers: { "api-key": key } }
)
<Chart data={data.items} />
Everything you need to visualize and integrate OHLC market data
The TradeWatch Chart Builder combines a query panel, a live OHLC chart, and production-ready API code generation in one resizable workspace. Configure any forex, stock, index, or commodity query, see the real price history, and copy the request directly into your application.
Interactive Candlestick Charts
Render real OHLC data as candlestick, line, or area charts. Pan and zoom across any date range. Color-coded candles make bullish and bearish moves instantly clear.
Query Panel
Select asset class, symbol, interval, and date range from a structured panel. All options come pre-populated with sensible defaults so you can start charting immediately.
Four Asset Classes
Chart stocks, forex pairs, global indices, and commodities from a single interface. Switch asset class and the symbol list updates instantly.
The Chart Generates Your Code
Every chart you configure produces a ready-to-copy OHLC API request in 6 languages. The symbol, resolution, start, and end timestamps are already filled in — paste it into your backtesting script, trading algorithm, or data pipeline and it runs immediately.
A focused workflow for OHLC market data analysis
Configure your forex, stock, index, or commodity query, visualize the OHLC price history, generate the API request code, and optionally stream live candles via WebSocket.
